conventional unit in the 136 to 174 MHz frequency band. There are two versions, Scan and System, with the System Version having a DTMF keypad. Up to sixteen (16) RF channels may be pre-programmed into the radio using a personal computer. Power output on each channel can be programmed for either high power (5 watts) or low power (1 watt). The power output on each channel can be toggled between high or low depended upon the pre-programmed setting with High/Low button on the left side panel. Each radio is capable of operation in 12.5 kHz or 25/30 kHz channel spacing systems. Rated system deviation for 12.5 kHz channel spacing is 2.5 kHz and 5 kHz for 25/30 kHz channel spacings. The KPC-300 radio contains three (3) buttons on the front panel. The KPC-400 contains three (3) buttons along with a twelve (12) button DTMF pad on the front panel. The scan function allows monitoring of any or all channels. Any channel may be scanned with or without a priority level. One channel can be programmed for Priority 1 (P1) and another for Priority 2 (P2), with any or all remaining channels programmed as non-priority channels (S). There is also Emergency mode transmission capability. A LCD display provides status display of the radio functions along with the display of the selected channel number. The Universal Device Connector (UDC), located on the side of the radio, provides connections for external audio accessories. This connector also allows the radio system personnel to connect programming equipment and program the per-channel and overall radio features.

trol, PTT button, MONITOR button, Channel Select switch, EMERgency button and a High/Low button. ON/OFF/VOLUME Turns radio on and off and adjusts audio listening level. When the radio is turned on, it will resume operation at the last operating state (channel, etc.) and the power-up alert tones will be sounded. Three (3) beeps indicate the radio is in the normal (receive mode); four (4) beeps indicates the radio is scanning. The operat- ing status of the radio will be dis- played in the Liquid Crystal Display (LCD) window. PTT BUTTON Pressing the PTT button on the side of the radio will key the radio transmitter. If the radio is not scanning, it will transmit on the selected (dis- played) channel. If the radio is scanning when the PTT button is pressed, the radio may be pro- grammed to transmit on the se- lected channel or on the current receive scan channel if the PTT is pressed during the scan hang time. If the selected channel is pro- grammed with Type 99 Tone De- code enabled, pressing the PTT button will disable Type 99 Tone Decode by switching the radio from the Selective mode to the Monitor mode. The PTT button must be released and then pressed a second time to key the radio. MONITOR The Monitor button has several functions. Its operation will vary depending upon programming. When the Monitor button is pressed and held down, all trans- missions will be heard even if Channel Guard protected. This permits channel monitoring be- fore transmitting. If the button is held for more than one (1) second, Channel Guard decode will tog- gle ON or OFF (if it is pro- grammed on the selected chan- nel). The Monitor button is also used to reset the radio after a Type 99 call is received. Quickly press and re- lease the button to reset the radio to receive the next Type 99 call. CHANNEL SELECT A rotary switch permits selection of channels. Rotating the switch clockwise increases the channels and counterclockwise decreases the channels. The channel is vis- ible by looking at the channel switch from the top or viewing the LCD display. EMERgency Pressing for at least one (1) sec- ond will transmit the emergency ANI code on the selected channel or pre-programmed HOME chan- nel. H/L Pressing for at least one (1) sec- ond selects the transmit power output by toggling from high-low or low-high. Three (3) buttons below the LCD display are used to control a vari- ety of operations when used alone and to control scan operations when used in conjunction with the S button. S Toggles the scan feature on and off. + Used in conjunction with the S button to add channels to the scan list or increase the channel’s pri- ority status. Used in conjunction with the Monitor button to enter the squelch adjust mode; then used to increase the level of squelch. - Used in conjunction with the S button to erase the selected chan- nel from the scan list. Used to decrease the level during squelch adjust mode. AE/LZB 119 1874 R2A 6

phone interconnect calls on radio systems equipped with this op- tion. The top row of buttons (1, 2, 3) provide access to up to three pre-programmed tele- phone interconnect numbers (see Telephone Interconnect Calls section). INDICATORS The Liquid Crystal Display (LCD) indicates the channel number. In addition there are seven (7) status indicators (flags) which show scan status, Type 99 Tone Decode status, transmit High/Low power status and Channel Guard status. The LCD backlighting will turn on anytime a control button is pressed. It will remain on for five (5) seconds after the button is released. If a control button is pressed while the backlight is on, the backlight remains on for another five (5) seconds. Backlighting may be programmed to remain off at all times. CHANNEL 12 The selected channel number is displayed in the LCD window.. When data is written into or read from the radio during PC pro- gramming, a P is displayed. STATUS TX/CAS LED Red light on steady - transmitter is active or keyed. Red light blinking - low battery voltage, recharge or replace bat- tery. Green on steady - channel busy indication, radio has detected a carrier on selected channel. SCN This status indicator turns on when the scan function of the ra- dio has been enabled. S When this indicator is on, the se- lected channel is a non-priority scan channel. P1 When this indicator is on, the se- lected channel is a Priority 1 scan channel. P2 When this indicator is on, the se- lected channel is a Priority 2 scan channel. PG When this indicator is on, the se- lected channel is programmed as a paging channel (Type 99 Tone Decode). The indicator will blink when the selected channel is placed in the monitor mode or the reception of a call. CG When this indicator is on, Chan- nel Guard is enabled on the se- lected channel. The indicator will go out when the selected channel is placed in the monitor mode. HI When this indicator is on, the se- lected channel is enabled for transmit high power. OPERATION Detail operating procedures are found in Operator’s Man- ual AE/LZT 123 1898. THEORY OF OPERATION Refer to the Block Diagram during the following expla- nations. TRANSMITTER The transmitter consists of an exciter Q201, PA module U201, auto power control (APC) U202 with Q202 and Q203, directional coupler Z201 and associated components. The local signal input of approximately 0 dBm to the transmitter is provided by the synthesizer to the exciter. An amplifier provides 17 dB of gain to produce +17 dBm (50 mW) of drive level to the PA module. During the receive mode, a band switch diode, D202, attenuates the receive first local oscilla- tor signal at the exciter input to reduce LO leakage at the antenna connector. The PA module is a 3-stage amplifier that provides a minimum RF power output of 7.0 watts at a battery voltage of 7.2 VDC. The RF power output is fed through the directional coupler Z201 to the antenna. A Schot- tky diode D201 converts the detected RF signal in the direc- tional coupler to a DC voltage to feed the auto power control circuitry.

The low pass filter Z101 and PI low pass filter, consisting of L121, C171 and C172, are provided to prevent excessive transmitter harmonics during the transmit function. TX/RX Antenna Switch The TX/RX antenna switch, consisting of D101, D102 and associated circuitry, provides the switching of RF output to the antenna and the receive signal to the receiver. During the receive function, the diodes are cut off, isolating the transmit circuit from the antenna. During the transmit func- tion, +5 volts is supplied to both diodes, turning them on and feeding the RF output from the transmitter PA module through the low pass filters via D101 to the antenna. The RF output is suppressed at the receiver RF front end filter by D102. RF Power Control The DC voltage detected by the directional coupler Z201 is supplied to comparator U202 where it is compared with the power reference voltage PWR_REF. This comparison voltage controls the bias voltage to the PA module by drive transistor Q202, and the output power is stabilized by the auto power control circuitry. PWR_REF is provided by the central processing unit (CPU) from information pro- grammed into the EEPROM. The PWR_REF voltage con- sists of six reference voltages: low frequency, middle frequency and high frequency band in both the high and low power modes. This power control provides the flatness of the RF output under varied temperature, voltage supply and frequency bandwidth conditions. RECEIVER The receiver has a dual conversion circuitry consisting of a receiver front end, RF amplifier Q101, 1st mixer Q102, 1st IF 45 MHz Monolithic Crystal Filter (MCF) Z102, IF ampli- fier/limiter/discriminator U101, 2nd IF 455 kHz ceramic filters Z107, Z104, Z105 and ceramic discriminator Z106. Receiver IF selectivity for 25/30 or 12.5 kHz channel spacing is determined by selecting the 455 kHz ceramic filter Z104 for 25/30 kHz spacing or Z105 for 12.5 kHz spacing. The demodulated receive audio at the AF OUT port of U101 is adjusted by Q104, R113 and R114 to produce a constant demodulated audio level input into the Audio Speech Processor (ASP) regardless of the receiver channel spacing mode, 12.5 or 25/30 kHz. The receive audio gain controlled by Q104, R113 and R114 is increased by 6 dB when the receiver is switched from 25/30 kHz to 12.5 kHz channel spacing. Received audio signals and beep tones are amplified by audio frequency power amplifier U407 to achieve the rated 0.5 W audio output power to speaker SP1. Short circuit protection for U407 consists of U416 and Q416. When AF PA AMP outputs, SP+ and SP-, are shorted together or shorted to ground, an excessive current will be sourced through transistor Q407 which is the pass transistor that provides bias to U407. This voltage drop across pass transistor Q407 will be compared in differential amplifier U416 and fed to voltage level translator Q416 which sends the excessive current status state information to the CPU. The CPU then sends a signal to Q407, turning it off and removing bias from U407. The software in the CPU assumes the short circuit is an intermittent short and resets for the excessive current state approximately six (6) seconds later. If the ex- cessive current state still exists, the CPU again turns Q407 off. After five retries, the CPU assumes the short circuit is not intermittent and keeps Q407 turned off. The short circuit condition must be removed before the radio is turned off and then back on to reset the CPU. Receiver Front End And Mixer The receive signal is fed from the antenna to a bandpass filter, a RF amplifier and an additional bandpass filter to remove the 1st IF image (Frx +90 MHz) and 1st IF/2 (Frx +22.5 MHz) and other out-of-band spurious responses. Total gain is approximately 8 dB with the first IF image rejection more than 68 dB. To achieve the required RF bandpass filtering charac- teristics across the frequency band, the first front end filter is electronically turned by changes in the BAND_SW volt- age which is fed to varactor diode D104. This voltage is generated by the D/A converter U421 from the CPU input. The frequency band is divided into three sub-split bands, one at the low end, one in the middle and one at the upper end of the band. The CPU determines which sub-split the desired receive frequency is in and provides the appropriate digital input to U421 to generate the correct BAND_SW signal for RF passband tuning. The receive signal is applied to dual gate GaAsFET mixer Q102 and mixed with the 0 dBm local oscillator injection from the synthesizer section to produce the 45 MHz first IF signal. 45 MHz Filter The mixer output is connected to the matching circuit and provided to the four pole 45 MHz MCF Z102. The 45 MHz crystal filter reduces the second IF image response (Frx -910 kHz) to meet spurious response specification. The output of Z102 is applied to the 2nd mixer in the IF IC U101 through the matching circuitry. U101 consists of the second mixer, two IF amplifi- ers/limiters, a quadrature detector and a noise filter amplifier. The second mixer downconverts the first IF 45 MHz signal to the second IF frequency of 455 kHz. Crystal resonator Y101 and associated components provide a 44.545 MHz second IF local oscillator signal. Y101 operated in the third overtone mode. AE/LZB 119 1874 R2A 8

ramic filter Z107 and then to the first IF amplifier/limiter. The first IF amplifier/limiter output is provide to either 455 kHz ceramic filter Z104 (for 25/30 kHz channel space mode) or Z105 (for 12.5 kHz channel space mode). These filters are switched by analog switches U102, U103, U107 and U108 depending on the desired channel spacing mode. Ceramic discriminator Z106 and internal quadrature detector provide the demodulated audio output signal at AF OUT. The de- modulated audio signal, filtered with an internal low pass filter (fc ≅47 kHz) is then routed to the baseband audio signal processor U401 and a noise squelch circuit. The noise squelch circuit consists of slow and fast squelch time constants and an additional high pass filter (fc ≅4.0 kHz). The slow squelch time constant is around 70 ms and is provided to U404-2. The fast squelch time constant is around 8 ms and is provided to U404-3. During scanning mode, only the fast squelch is monitored by the CPU. In all other modes, the slow squelch is monitored. Synthesizer The synthesizer circuit generates all transmit and receive RF frequencies. This circuit consists of synthesizer IC U302, temperature compensated crystal oscillator (TCXO) U303, voltage controlled oscillator (VCO) U301 and associated loop filter circuitry. The VCO operates at the transmitter frequency during transmit function and 45 MHz above the receive frequency during the receive function. The synthesizer is controlled by the CPU. Frequency stability is maintained by the TCXO module. A portion of the VCO output is applied to the synthesizer IC and divided by 64/65 dual modulus prescaler, which is set by pulse swallow counter A and programmable counter B to provide a 5 kHz or 6.25 kHz output for comparison with a reference signal. The reference signal is derived from the 12.8 MHz TCXO module. The synthesizer IC divides the 12.8 MHz signal down to the 5 or 6.25 kHz signal. (The KPC-300/400 PC Programming Software will only permit synthesis of transmit or receive frequencies that are integer multiples of 5 or 6.25 kHz. Other frequencies cannot be input into the radio’s personality. The synthesizer’s default phase lock frequency is 5.0 kHz. If the frequency to be synthesized is not an integer multiple of 5 kHz, the synthesizer’s phase lock frequency will be 6.25 kHz.) An unlock detector is used to prevent transmission when the frequency synthesizer is unlocked. Audio modulation from the Audio Signal Processor (ASP) IC U401 is applied to the VCO modulation input via amplifier U402 and the TCXO modulation input via ampli- fier U403. The gain of U402 is adjusted dependent upon the channel spacing mode of the radio. In the 25/30 kHz channel space mode, U418 is open-circuited, removing R453 from being in parallel with R411. In the 12.5 kHz channel space mode, U418 is short-circuited, placing R453 in parallel with R411 and reducing the transmitter audio gain by a factor of two. (This establishes the 5 kHz maximum frequency devia- tion for 25/30 kHz channel spacing and the 2.5 kHz maxi- mum frequency deviation for 12.5 kHz channel spacing.) VR403 and VR402 are adjustable to provide a constant modulation flatness for voice audio and Channel Guard (CG) and Digital Channel Guard (DCG) sub-audible modulation. MOSFET transistor Q316 is turned on during the transmit mode to change the loop gain in order to get lower modula- tion frequency response. A ripple filter, consisting of Q312, C312 and R331, provides a filtered 4.7 VDC to the VCO to improve the phase noise characteristic of the receiver local injection signal for enhanced receiver performance for adja- cent channel selectivity, intermodulation and FM hum and noise. Audio Logic The audio logic section consists of CPU U404, Audio Signal Processor (ASP) IC U401, EEPROM U406 and asso- ciated components. The CPU controls all radio operations. The EEPROM contains the personality data and the align- ment data. CPU The CPU contains the LCD controller, LED controls, 32k bytes of ROM, 1k byte of RAM, an 8-channel A/D converter and a 2-channel D/A converter. The CPU generates DTMF tones, alert tones, beep tones, GE-STAR (ANI) codes and Digital Channel Guard (DCG) encode codewords. The DCG encode codeword from the CPU is applied to a low pass filter in the ASP IC U401 and summed with the voice signal at U402. Received DCG codewords and Type 99 tones from the ASP U401 are supplied and decoded by the CPU. AUDIO SIGNAL PROCESSOR U401 The ASP IC U401 contains the CG encoder and decoder, pre-emphasis audio shaping filters, de-emphasis audio shap- ing filters, limiter, post-limiter filter (i.e., splatter filter) and various Switched Capacitor Filters (SCF). U401 generates CG tones controlled by the CPU. CG and DCG sub-audible modulation signals are summed with the voice audio signal at op-amp U402 and supplied to the VCO and TCXO modu- lation inputs. The demodulated audio signal from IF IC U101 can provide voice signal information, CG tones, DCG codewords and Type 99 two-tone sequential information. CG tones are filtered by a tone filter and decoded in the ASP. DCG code- words are filtered by the tone filter and input to multiplexer U417. Type 99 tones are filtered by a bandpass filter and also input to U417. Multiplexer U417 selects either the DCG or Type 99 signals, outputs the signal to a comparator to “square” the signal to a TTL level digital waveform and then sends the digitized signal to the CPU for detection. AE/LZB 119 1874 R2A 10

it can be optionally mixed with DTMF or GE-STAR (ANI) encode signals. These baseband signals are bandpass filtered, run through a post-limiter filter (splatter filter) and then summed at op-amp U402 with CG tones or DCG codewords. CLOCK SHIFT The CPU uses a nominal 7.3728 MHz clock frequency, which is divided down to 3.6864 MHz to become the clock frequency input provided to the ASP IC U401. Harmonics of this clock frequency can potentially interfere with the per- formance of the transmitter and receiver, producing self-qui- eting “beat” notes at specific receiver frequencies or producing an audio whine at specific transmitter frequencies. A clock shift can be programmed for each channel’s receive and/or transmit frequency to move the potentially interfering harmonics of the microprocessor clock frequency. The mi- croprocessor clock frequency is shifted more than +100 ppm, effectively moving potentially interfering clock harmonics off-channel. POWER SUPPLY The battery voltage, provided by six nickel cadmium cells, is a nominal 7.5 volts. This voltage is provided to the series regulators via a 4 amp fuse F401. The regulated supply provides +5 volts for the logic section, the analog section, receiver and transmitter sections. The +5.5 volts for the PLL frequency synthesizer section is also provided. RADIO PROGRAMMING PC PROGRAMMING The KPC-300/400 Portable Radio is programmed using an IBM compatible personal computer equipped with a RS- 232 serial port. Adapter TQ-3370 provides the RS-232 serial interface and the cable between the PC and the adapter box. Programming Cable RPM 113 2472/1 provides the connec- tion from the adapter box to the radio’s Universal Device Connector (UDC). The programming software is AE/LZY 213 761. PROGRAMMABLE FEATURES The following features are programmable on a per-chan- nel basis: • Receive Frequency • Transmit Frequency • Channel Busy Lock-Out • Squelch Tail Elimination (STE) • Channel Guard Encode/Decode (Tone or Digital) • Type 99 Tone Decode • Automatic Number Identification (ANI) • Telephone Interconnect DTMF Keypad Enable (KPC-400 only) • RF Power (Hi or Low) • Rx Frequency µP oscillator shift • Tx Frequency µP oscillator shift • Channel Spacing (either 12.5 kHz or 25/30 kHz) The following features are programmable on an overall radio basis: • Display Backlighting • Alert Tones • Emergency Home Channel • • Three (3) Auto-Dial Telephone Numbers (KPC-400 only) • Carrier Control Timer • Hi/Low RF Power Button Enable/Disable • Scan Options CHANNEL BUSY LOCK-OUT If channel busy lock-out has been programmed on the selected channel, the transmit function will be inhibited when the operator presses the PTT button while the radio detects a carrier on the channel unless the carrier is modu- lated with the corresponding Channel Guard tone or code for that selected channel. The radio will immediately begin transmitting when the carrier disappears. Channel busy lock- out continues to function if Channel Guard decode is dis- abled with the MONITOR button. The channel-busy feature is programmable on a per-channel basis. Type 99 cannot be programmed on a channel with channel busy lock-out. CHANNEL GUARD Channel Guard (CG) provides a means of restricting calls to specific radios through the use of Continuous Tone Coded Squelch System (CTCSS) tone frequencies ranging from 67.0 Hz to 250.3 Hz. Digital Channel Guard (DCG) also can provide a means of restricting calls through the use of 104 Continuous Digital Coded Squelch System (CDCSS) codes. [There are 83 standard TIA/EIA and 21 unique Ericsson DCG codewords.] Each channel may be programmed for encode/decode, encode only, decode only or for no CG or DCG. Both tone frequencies and digital codes may be used. The tones and codes are listed in Tables 1 and 2. SQUELCH TAIL ELIMINATION (STE) STE is used with tone and Digital Channel Guard to eliminate squelch tails. The STE burst is transmitted when the microphone PTT is released. The receiving radio decodes the burst and mutes the receiver audio for 250 ms. This mute time allows the transmission to end and to eliminate the squelch tail. STE is enabled for transmit and/or receive through PC programming. AUTOMATIC NUMBER IDENTIFICATION (ANI) Automatic Number Identification is a 320 ms burst of code (GE-STAR) that is generated at the beginning of each transmission to identify the radio unit to the dispatcher. If AE/LZB 119 1874 R2A 11

sion to indicate when conversation can begin as the micro- phone is disabled until the ANI transmission is completed. Systems with CG require that ANI be delayed long enough for the system to respond before ANI can be decoded. A programmable delay is provided to meet this requirement. For example, a delay of 350 ms requires the operator to wait for 670 ms after pressing the PTT before conversation can be started. If desired, the ANI message can be programmed to be sent at the end of a transmission. CARRIER CONTROL TIMER This feature, programmable on a per-radio basis, prevents unnecessary channel traffic and radio damage if the transmit timer limit is exceeded. If the programmed timer times-out during a transmission, the radio will beep and stop transmit- ting. The beeping tone will continue until the operator re- leases the PTT button. Releasing the PTT button resets the timer. TYPE 99 TONE DECODE The radio is programmable to power-up in either Selec- tive (Type 99) or Monitor mode for channels programmed for Type 99 decode. When Selective mode is chosen, the radio operates as a tone and voice receiver and allows only those calls that are tone coded for the radio to be heard. Selecting Monitor mode allows all calls with the correct Channel Guard (if pro- grammed) on the channel to be heard. In either mode, when a correct T99 and Channel Guard (if programmed and enabled) have been decoded, a series of intermittent beeps will be heard to alert the operator of an incoming call. The PG status flag will blink in the display to indicate that a call has been received. If the Selective mode was chosen, the radio switches automatically to Monitor mode. At the end of the message, if Selective mode is desired, press and release the MONITOR button to reset the Type 99 tone signalling function. The PG status flag will cease blink- ing. While in Selective mode, the radio can be put in Monitor mode by pressing and releasing the PTT. A series of beeps is sounded whle the PTT is pressed to indicate that no transmission has occured and the monitor mode has been selected as indicated by with the blinking of the PG status flag. A second press of the PTT will result in normal transmission. The radio is programmable to decode any Ericsson or Motorola decode combinations from any one of two T99 tone tables on a per-channel basis. Transmit and/or receive Chan- nel Guard can be programmed to any channel with Type 99. Type 99 receive Channel Guard (if programmed) can be disabled by pressing the MONITOR button for more than three (3) seconds. If a Type 99 channel is in the scan list and scan is enabled, Type 99 tones are ignored. Scanning is provided on a carrier and Channel Guard basis only. TELEPHONE INTERCONNECT (DTMF) (KPC-400 ONLY) The operator may make telephone interconnection calls on radio systems equipped for this option. Specific proce- dures for placing these calls are determined by the operating system. There are two methods to make telephone interconnect calls. One method uses the top three keys ( 1,2,3) to send one of three pre-programmed numbers. The other method is to use the keypad ( 0-9) to manually enter the telephone number. The keypad is not active until the PTT button is pressed. Therefore, the PTT button must be pressed at all times when operating any button on the DTMF keypad. Communications takes place in a simplex mode. You cannot talk and listen at the same time. The PTT button must be pressed each time you wish to talk and, released when you wish to listen. SCAN The scan feature permits monitoring of up to 16 receive channels. The scanned channels can be any frequency within the frequency band limits of the radio and can be Channel Guard protected (tone or digital). Any channel can be scanned with or without a priority level. One channel can be programmed for Priority 1 (P1), another for Priority 2 (P2) or any or all remaining channels programmed as Non-Priority (S). The radio can be pre-pro- grammed to permit an operator front panel selectable scan list, a fixed Priority 1 channel or a selected Priority 1 channel using the channel select switch. If the radio’s personality was programmed to power up in the Selective mode, the Type 99 decoder will automatically reset when the channel is changed. If, however, the radio’s personality was programmed to power up in the Monitor mode, the Type 99 decoder will NOT automatically reset when the channel is changed, and the user must manually key the MONITOR button to reset the Type 99 decoder. NOTE Resetting Type 99 from Monitor to Selective mode does not affect Channel Guard switch setting. NOTE AE/LZB 119 1874 R2A 12

Hum modulation of co-channel stations may "false" Channel Guard decoders. 2. Do not use adjacent Channel Guard tone frequencies in systems employing multiple Channel Guard tones. Avoid same-areas co-channel use of adjacent Channel Guard tones whenever possible. As stated in TIA/EIA-603, there is a possibility of decoder falsing. 3. To minimize receiver turn-on time delay, especially in system using Channel Guard repeaters or receiver voting, choose the highest usable Channel Guard tone frequency. Do not use tones below 100 Hz when it is necessary to meet the receiver response time requirements as specified in TIA/EIA-603.

description. • Simple Scan - describes the condition when scan is enabled and there is no activity on any channel in the scan list. • Priority Scan - describes the condition when scan is enabled and the priority scan channel is sampled during the scanning of the channels on the scan list. • Channel Guard Scan - describes the condition when scan is enabled and tone or digital Channel Guard must also be detected before locking on any chan- nel. • Selected Channel - indicates that this is the last channel that the operator selected with the channel select switch. This channel is displayed unless scan is enabled and activity is detected on another chan- nel being scanned. • Receive Channel - indicates the channel that has been detected and identified with the correct carrier and Channel Guard (if enabled). The receive chan- nel number will be shown in the display. • Scan List - indicates an internal list either pre-pro- grammed or programmed from the front panel that includes each channel status that will be scanned when the scan mode is enabled. • Non-Scan Channel - indicates a channel that is not in the scan list and will not be scanned when scan is enabled. • Non-Priority Channel - indicates that this channel is on the scan list. Activity on this channel will be interrupted by activity on either the Priority 1 or Priority 2 channel. • Priority 2 Channel - indicates that this channel is also on the scan list. Activity on this channel will interrupt any activity on any non-priority channel. However, activity on this channel will be inter- rupted only by activity on the Priority 1 channel (if on scan list). • Priority 1 Channel - indicates that this channel is also on the scan list. Activity on this channel will interrupt and supercede any other channel activity. • Channel Activity - indicates the presence of a cor- rect carrier with correct Channel Guard (if pro- grammed). • Hang Time - describes the time interval (pre-pro- grammable) that a channel remains locked to a frequency although no channel activity is present. This condition arises after channel activity has stopped or the PTT button has been released. • Fixed Priority 1 Channel - indicates that the channel has been pre-programmed as the Priority 1 scan channel and cannot be changed by the operator. • Selected Priority 1 Channel - indicates that the channel selected by the channel select switch will be the Priority 1 scan channel. The operator can still select the Non-Priority and Priority 2 channels. Pre-Scan Operation A scan list must be created before scan operation can be used. The scan list can be created in several ways. The radio will not go into the scan mode when no channel are pro- grammed or in a scan list. • Fixed Programmable - the scan list is pre-pro- grammed using the PC programming softwaare and cannot be changed by the operator. • Front Panel Programmable - the scan list is created by the operator using the front panel controls. • Selected Channel Programmable - the operator cre- ates the scan list for all Non-Priority and Priority 2 channels. The Priority 1 channel is selected by the channel select switch. This is also pre-programma- ble using the PC programming software. ALERT TONES Alert tones or “beeps” are sounded when a button is pressed and when the operating status of the radio changes. All alert tones may be programmed to be remain off. POWER-UP SELF-TEST Each time the radio is turned on, it will perform power-up self-test. All display segments will turn on, and after success- ful completion of the test, the radio will change to the last operating state (channel, etc.) and sound three (3) or four (4) beeps. Three (3) beeps sound if the radio is operating in the normal (not scan) state. Four (4) beeps will sound if the radio is scanning. The status will be indicated in the LCD. If the radio fails the self-test, no beeps will be sounded. TYPE 99 ALERT TONE The Type 99 alert tones, indicating a received Type 99 call, may be enabled or disabled by programming. If the programmed tone sequence is detected, the radio will pro- duce an intermittent series of beeps. If the alert tones are disabled, no alert tones will be present when a Type 99 call is received. The Type 99 alert tones can only be disabled by disabling ALL alert tones. ANI ALERT TONE The Automatic Number Identification (ANI) alert tone beep can be enabled or disabled by programming. If the alert tone is enabled, a beep will sound after the PTT is pressed to indicate to the operator to begin voice transmission. Some communication systems require a time delay before voice transmission begins. If the alert tone is disabled, no beep will sound. AE/LZB 119 1874 R2A 14

Similar to the ANI alert tone, the EMERGENCY GE- STAR alert tone can be enabled or disabled by programming. If enabled, a beep will be heard after each EMERGENCY transmission. SCAN ALERT TONE The radio will sound a beep when the S button is pressed. PRIORITY-ONE (P1) SCAN If the Priority 1 alert tone is enabled by programming and the radio receives a signal on the Priority 1 channel when scanning, the radio will sound a beep. RADIO/CHANNEL FAILURE The simultaneous flashing of the LCD display and the sounding of beeps indicates the synthesizer is unable to correctly lock on the selected channel. At this time the radio changes to a mute condition and no audio is heard from the speaker when receiving and the transmit is inhibited if the PTT button is pressed. Select another channel, change the battery pack or have the radio repaired. SCAN OPERATING MODES Simple SCAN Once SCAN is activated, the radio will perform a Simple SCAN routine. This routine is performed when there is no activity on any of the channels that are in the Scan list. The scanning list at right, is an example of the rou- tine performed when there are more than four (4) channels in the Scan list. np6...np5...np4...np3...P1.. .P2...np2...np1...np6...np5. ..P1...P2...np4...np3...np2.. .np1...P1...P2, etc. (The abbreviation "np" indicates a non-priority channel, and P1 and P2 indicate Priority 1 and Priority 2, respec- tively.) The scanning list at right, is an example of the rou- tine performed when there are less than four (4) chan- nels in the Scan list. np3...np2...np1...P1...P2...n p3...np2...np1...P1...P2, etc. The above scanning orders assume that Priority 1 and Priority 2 channels exist. If they have not been assigned, their positions in the scanning order are eliminated. PTT Pressing the PTT switch causes the ra- dio to transmit on the selected channel frequency and to stop the scanning rou- tine. A programmable hang time (0.3 to 5.0 seconds) will start as soon as the PTT switch is released. Scanning will resume at the end of the hang time. The hang time is a PC programmable option and can be enabled or disabled. Channel Change Any channel change will change the selected channel and show it in the display window. A channel change will also stop the scanning routine for a fixed, 2-second hang time. If no ac- tivity is detected on this new selected channel during this 2-second hang time, scanning will resume. Priority SCAN As soon as any activity is detected on a channel, the radio will change the scanning mode from Simple SCAN to Prior- ity SCAN. The new receive channel will appear in the LCD window. If the receive channel is a Non-Priority channel, both Priority 1 and Prior- ity 2 channels will be sam- pled (scanned) every 500 milli-seconds in the order indicated at the right. P1...P1...P2...P1...P1...P2.. .P1...P1...P2, etc. • If a Priority 1 channel has not been established, the radio will only break away to sample the Priority 2 channel every 1.0 second. • If a Priority 1 channel has been established but not a Priority 2 channel, the radio will break away to sample the Priority 1 channel every 500 millisec- onds. • If neither a Priority 1 or Priority 2 channel has been established, the radio will lock on this channel until activity on this channel goes away. • When the receive channel is a Priority 2 channel, the radio only samples Priority 1 channel every 500 milliseconds. Priority channels will continue being scanned during hang time. NOTE AE/LZB 119 1874 R2A 15

other channels will be scanned. Once activity on the receive channel has ended, a pro- grammable hang time (0.3 to 5.0 seconds) is started. Scan- ning will resume at the end of the hang time if there is no activity on that channel. The selected channel will appear now on the display. Note that Priority channels will continue being scanned during hang time. To alert the operator of an incoming call on the Priority 1 channel, an option is available to sound a beep upon receiv- ing this Priority 1 channel. Scanning for Channel Guard The scanning for Channel Guard option may be selected if, in addition to carrier activity alone, a correct Channel Guard is also required to lock on a channel when scanning. This option is selected on an individual radio basis. Scanning Priority channels with the wrong Channel Guard will change the scanning rate as follows: Priority 1 with wrong Channel Guard: The radio will change its Priority 1 sample rate from 0.5 seconds (.5 seconds) to 2.5 seconds, but it will still sample the Priority 2 channel every 1.0 second. Priority 2 with wrong Channel guard: The radio will change its Priority 2 sample rate from 1.0 second to 5.0 seconds, but will continue to sam- ple the Priority 1 channel every 500 millisec- onds (.5 seconds). PTT The operator has two PC programma- ble options to select from in regard to what channel to transmit on. The op- erator can choose to transmit on the selected channel or on the receive channel. The transmit channel will be shown on the display. Releasing the PTT switch will unkey the transmitter and start the programmable hang time (0.3 to 5.0 seconds), if enabled. Scan- ning will resume again at the end of the hang time unless there is activity on that channel. Channel Change Any channel change will change the selected channel. The receive channel, if any, will stop being displayed/heard and replaced by the new selected chan- nel. The scanning routine is temporar- ily stopped for a fixed 2 seconds and will resume again if there is no activity on the selected channel. TONE PROGRAMMING An IBM-compatible personal computer using MS-DOS and a Programmer Interface Box plus the proper program- ming software is used to program the Type 99 tones, Channel Guard tones, and Channel Guard digital code. The Program- mer Interface Box is connected between the UDC on the side of the radio and the back of the personal computer. Refer to Programming Guide for details. Two sets of Type 99 tones can be programmed in the radio. Any channel can be programmed to decode any call or all calls based on any one of the two tone sets. Individual, group, and super group paging can be used. Motorola for- mats are also acceptable. PG is displayed on the LCD when that channel has been programmed to receive Type 99 calls. Both receive and transmit Channel Guard may also be programmed to any channel with Type 99 tone. An Intermittent beep is sounded to alert the operator of an incoming Type 99 call. Upon receiving a call, the radio will open the audio and flash the PG indicator until it is reset by momentarily press- ing the MONITOR button. The optional Type 99 programming provides individual, group, and super group call decode. The Motorola-format- ted, two-tone, sequential signalling schemes can also be decoded. In Type 99 tone systems, calls will not be heard from the receiver until the proper two tones are detected. When the second tone is decoded and recognized as correct, an alert tone sounds during the remaining portion of the second tone. The receiver audio path opens and remains open to receive messages until the decoder is reset. The PG indicator will also flash to show a call has been received. The radio can be programmed with up to two separate tables of tones. Either the Ericsson Type 99 format or the Motorola format can be assigned to each tone table. The tone decoder (individual, group, and super group for Ericsson format or individual, group, and quick call for the Motorola format) can be enabled individually for each channel. Once enabled, one of the two tone tables can be selected for each channel. Priority channels will continue being scanned during hang time. NOTE If a Type 99 channel is in the Scan list and SCAN is enabled, Type 99 tones are ignored. Scanning is done on a Carrier and Channel Guard basis only. NOTE AE/LZB 119 1874 R2A 16

radios in a group. The Super Group Call (in Ericsson Tone systems) or Quick Call (in Motorola tone systems) allows communications between all radios in a system. TYPE 99 FORMAT Tone frequencies in the Ericsson tone system fall within the range of 517.5 to 967.5 Hz. In the tone format, the first tone can be from Tone Group A (for individual or group calls) or from Tone Group C (for super group calls). The second tone may be from Tone Group B (for individual calls) or from Tone Group D (for group or super group calls). The tone format is illustrated as follows. INDIVIDUAL CALL FORMAT <...1.0 SEC...> ±20% TONE A <...200 MS...> ±25% GAP <..1.0 SEC..> +300%,-0% TONE B GROUP CALL FORMAT <...1.0 SEC...> ±20% TONE A <...200 MS...> ±25% GAP <..1.0 SEC..> +300%, -0% TONE D SUPER GROUP CALL FORMAT <...1.0 SEC...> ±20% TONE C <...200 MS...> ±25% GAP <..1.0 SEC..> +300%, -0% TONE D For example, assume the paging number to be 123; the first digit of the paging number is a "1." Look in Table 3 and read down the column labeled "100’s Digit" to a "1." Read horizontally across the column labeled "10’s Digit." The Tone Group is B. The second digit of the paging number is a "2." The tone number is B2. Look in Table 4 and down the column labeled "Tone Designator" to find B2. Read horizontally across the column labeled "Tone Frequency." The first tone frequency is 787.5 Hz. To determine the second tone frequency, look in Table 3 and, as before, find the first digit of the paging number ("1"). The second Tone Group is A. The third digit of the paging number is a "3" and the Tone Designator is A3. In Table 4, read down the column labeled "Tone Designator" and find A3. Read horizontally across the column labeled "Tone Frequency." The second tone frequency is 802.5 Hz. For different paging numbers, locate the first digit in the "100’s Digit" column and determine the tone frequencies as described in the example. Tone D is the diagonal tone used (in Ericsson systems only) when the first and second tone frequencies are the same. The standard frequency for Tone D is 742.5 Hz, but may be programmed with any tone frequency. Table 3 - Ericsson Tone Groups 100’s Digit 10’s Digit For First Tone 1’s Digit For Second Tone 0 1 2 3 4 5 6 7 8 9 A B B A C C C A B NOT USED A A B B C A B C C MOTOROLA FORMAT Tone frequencies in the Motorola tone system are within the range of 288.5 to 1433.4 Hz. In the Motorola tone format, the first tone may be one of three tones: A for Individual Call, B for Quick Call, and C for Group Call. The second or final tone is B in all cases. The Motorola tone format is illustrated as follows: INDIVIDUAL CALL FORMAT <..1.0 SEC..> (Minimum) TONE A <..NONE..> (Minimum) GAP <..3.0 SEC..> TONE B GROUP CALL FORMAT <..1.0 SEC..> (Minimum) TONE C <..NONE..> (Minimum) GAP <..3.0 SEC..> TONE B QUICK CALL FORMAT <..............................8 SEC..............................> TONE B Individual Call Tables 5 and 7 may also be used to determine the tone frequencies. The first digit of the code determines the tone group used in the code (see Table 5). Then Table 6 is used to determine the actual tone frequencies. For a code of 124, the tone groups used are shown in Table 5. Tone A and Tone B are both located in Tone Group 1 and Tone B is tone number 4. Refer to the following examples for additional information. The radio is able to recognize the A, B, and C tones. Individual, Group, and Quick Call formats may be used simultaneously. NOTE AE/LZB 119 1874 R2A 17

The digit "0" in Table 5 (First Digit of Code) shows the Tone A is in Tone Group 4 and Tone B is in Tone Group 2 (see Table 5). Tone number 9 in Tone Group 4 is 524.6 Hz. Tone number 8 in Tone Group 2 is 879.0 Hz. Example 2 - Code 265: The digit "2" in Table 5 shows that both Tone A and Tone B are in Tone Group 2. Tone number 6 in Tone Group 2 is 788.5 Hz. Tone number 5 in Tone Group 2 is 746.8 Hz. Group Call (Quick Call Format) In Group Call applications, the tone group is determined by Table 7, while the frequency is determined by Table 6. Refer to the following examples. Example 1- Group Call Code 07 (also code 27 and 37): The digit "0" in Table 7 shows that Tone B is in Tone Group 2 along with 20 to 29 and 30 to 39. Tone number 7 in Tone Group 2 is 832.5 Hz (see Table 6). Example 2 - Group Call 98 (also 48 and 88): The digit "9" in Table 7 shows that Tone B is in Tone Group 4 along with 40 to 49 and 80 to 89. Tone number 8 in Tone Group 4 is 496.8 Hz.

radio. This procedure should be used whenever a board or component is replaced or the operation of the radio is in doubt.. Almost all alignment and checks can be accom- plished through the Universal Device Connector (UDC) us- ing the maintenance section of the PC Programming Software. The setting of the transmitter deviation requires the removal of the front case of the radio to adjust VR402 and/or VR403. TEST EQUIPMENT The following test equipment is recommended for radio alignment: • Communications Monitor (HP8920B or equivalent) • DC Voltmeter (1 megohm input impedance) • DC Power Supply (7.5 volts at 5 amp) • IBM or compatible personal computer • PC Programming Software • Programming Adapter Box TQ-3370 with Interface Cable • Radio Programming Cable • DC Power Adapter • DC Power Cable • RF Coaxial Cable (50 ohms) Initial Setup 1. Remove the channel select and volume knobs. Then remove top cover and front case from radio. 2. Attach DC power adapter to radio and set voltage on power supply for 7.5 volts. 3.

BATTERY INFORMATION CHARGE BEFORE USING Insert the radio into the slot on the charger and ensure that the ON/OFF/VOLUME control is in the OFF position. Con- nect charger to an AC power source. Charge the battery for the first time at least 14 hours but no longer than 48 hours. Over-charging may reduce battery life. RECHARGING THE BATTERY Recharge the battery when you experience difficultity in receiving or sending a message. Also the battery may need recharging when the red TX indicator is blinking. Chargers are available with nominal charge times of one to 14 hours. Combinations include single and multiposition chargers. When charging a battery pack that is attached to a radio, always turn the radio OFF to ensure a full charge. For specific instructions, refer to the applicable charger Opera- tor’s Manual. Charging in non-Ericsson equipment may lead to battery damage and void the battery warranty. Batteries which have been stored (charged or discharged) will generally not be capable of full capacity until the batter- ies have been fully cycled two or three times. (Charging the battery in an Ericsson rapid charger and then discharging the battery pack with the radio until low battery is indicated is considered one cycle.) INSTALLING THE BATTERY PACK 1. Ensure the ON/OFF/VOLUME control knob is in the OFF (detent) position. 2. Align the battery pack tabs with the battery mounting plate slots on the back of the radio (see Figure 6). 3. Insert the tabs into the slots, push down and slide the battery toward the battery latch until the battery latch clicks into place. REMOVING THE BATTERY PACK 1. Ensure the ON/OFF/VOLUME control know is in the OFF (detent) positon. 2. Press the battery release button to release the battery. 3. Remove the battery pack by sliding it back until it stops. Then lift up and away until it separates from the radio. BATTERY CARE & MAINTENANCE • Your charger is intended for indoor use only. Keep the charger and/or wall cube dry.

Call Toll Free 1-800-8-BATTERY for information and/or procedures for returning rechargeable batteries in your state. Figure 6 - Installing And Removing The Battery Pack AE/LZB 119 1874 R2A 21

ating a portable radio. Operating the radio in low areas or terrain, under power lines or bridges, inside of a vehicle or in a metal or steel framed building can severely reduce the range of the unit. Mountains and buildings can also reduce the range of the unit. In areas where transmission or reception is poor, some improvement may be obtained by ensuring that the antenna is vertical. Moving a few yards in another direction or mov- ing to a higher elevation may also improve communications. Vehicular operation can be aided with the use of an externally mounted antenna. Battery condition is another important factor in the trouble free operation of a portable radio. Always properly charge the batteries. EFFICIENT RADIO OPERATION Hold the portable radio approximately three inches from your mouth and speak into the microphone at a normal voice level. Keep the antenna in a vertical position when receiving or transmitting a message. Do not hold the antenna when receiving a message and, especially, do not hold when transmissing a message. ANTENNA CARE AND REPLACEMENT Do not use the portable radio with a damaged or missing antenna. A minor burn may result if a damaged antenna comes into contact with the skin. Replace a damaged antenna immediately. A missing antenna could damage your portable radio. Use only the supplied or approved antenna. Unauthorized antennas, modifications or attachments could damage the radio unit and may violate FCC regulations. ELECTRONIC DEVICES RF energy from your portable radio may affect some electronic equipment. Most modern electronic equipment in cars, hospitals, homes, etc. are shielded from RF energy. However, in areas that instruct you to turn off two-way radio equipment, always observe the rules. If in doubt, turn it off. AIRCRAFT Always turn off your portable radio before boarding any aircraft. • Use it on the ground only with crew permission • Do not use it in the air BLASTING AREAS To avoid interfering with blasting operations, turn your radio OFF when in a "blasting area" or in areas posted "turn off two-way radio". Remote control RF devices are used by some construction crews to set off explosives. POTENTIALLY EXPLOSIVE ATMOSPHERES Areas with potentially explosive atmosphere are often, but not always, clearly marked. These may be fueling areas, such as gas stations, fuel or chemical transfer or storage facilities, and areas where the air contains chemicals or particles, such as grain, dust or metal powders. Sparks in such areas could cause an explosion or fire resulting in bodily injury or even death. Turn OFF your radio when in any area with a poten- tially explosive atmosphere. It is rare, but not impossible that the radio or its accessories could generate sparks.

To replace the swivel mount, place the end of the swivel in the grooves of the holder on the back of the radio and slide the mount up until it snaps into place. MAINTENANCE It is highly recommended that no repairs to this unit be attempted. All defective units should be returned to Ericsson Inc. for repair and/or replacement. Parts List, component drawings and schematic diagram are provided for reference only. DISASSEMBLY Disassembly of the KPC-300/400 Portable Radio Units should be done very carefully. Damage to the water- tight/dustproof seals could occur when disassembling or reassembling the unit. The following procedure should be followed to permit removal of the front housing. 1. Remove the battery pack. 2. Remove the two screws on bottom of casting holding the plastic front to the casting. 3. Remove the rubber overcoat from both the volume and channel switches. 4. Remove the plastic bushings from the shafts of the volume and channel switches. 5. Remove the nut holding the volume control to the top panel 6. Carefully remove the top cover. 7. The front housing is now ready for removal. This housing is still attached to the casting by detents in the plastic housing engaging bumps in the casting. a. Insert a narrow object between the casting and the plastic cover along the sides of the radio and gently spread the plastic housing away from the casting. b. Gently lift the plastic housing, starting at the bottom of the radio, and working upwards to the top of the radio (top of plastic housing held by pin at top of casting). 8. Reassemble the radio in reverse order. Water seals are provided around the battery contacts, the UDC connector and the volume and channel select switches. A watertight/dustproof gasket is located between the speaker cone and the grille covering. All pushbutton switches use silicon rubber gaskets and are pressed against the plastic housing to insure watertight seals. There are no electronics under the plastic rear cover which merely covers the latching mechanism and provides appearance. NOTE When reassembling the radio, failure to replace and/or seat the watertight/dustproof gaskets and seals may affect the integrity of the seals and affect the weatherproof and dustproof feature of the radio. All weatherproof sealing is done between the casting in the front cover. CAUTION AE/LZB 119 1874 R2A 23
