Operation and Installation 11 Doc.-No. 01.143A.010.71e / Revision 1.00 2.4 Frequency Setting Frequency setting is always done by the two steps of 1. Entering a new standby frequency to the desired value, and then 2. Interchanging the new standby frequency and the previous active frequency by using the swap button . . Entering a new standby frequency can be done by a) Manual input, b) Recall of previously stored frequencies from the user memory (memory locations 1-20), or c) Recall from the list of the last 10 used frequencies. 2.4.1 Automatic Selection 8.33 / 25 kHz Channel Bandwidth Whether a frequency is used with channel width 8.33 kHz or 25 kHz, is automatically determined by the value of the frequency entered, and requires no additional user activity. The numbering scheme that is used for distinction of the two channel widths is internationally standardized by the ICAO, and consistently used in official documents (like e.g. VFR navigation charts) as well as in the voice phraseology used by ATC radio communication. Channels used with 25 kHz width are entered in multiples of 25kHz: 123.500, 123.525, 123.550, 123.575, 123.600 etc. These are compatible with the old 25 kHz-only radios. To use the same frequencies with 8.33 kHz width, the frequency values entered are increased by 5kHz: 123.505, 123.530, 123.555, 123.580, 123.605 etc. For more detailed information please refer to chapter 5.1 – but as said above, for correct channel width selection this knowledge is not required.

Operation and Installation Doc.-No. 01.143A.010.71e / Revision 1.00 12 2.4.2 Manual Frequency Input The standby frequency is input by  Selecting with the ► button which part of the frequency to change, and  Changing the selected part with the FREQ rotary knob. The swap button  interchanges the newly set standby frequency and the former active frequency. When having the channel selection configured for 8.33 kHz steps (see 3.1), the frequency is input in three steps: SBY 118.910  SBY 118.910  SBY 118.910 In order to speed up the entering of new frequencies, it is possible to configure the radio to allow entering of those frequencies only that are used with 25 kHz channel width. Please refer to chapter 3.1 for information on this configuration. However, when choosing this option, please keep in mind to re-enable 8.33 kHz channel selection before flying into areas where 8.33 kHz channels are used.

Operation and Installation 13 Doc.-No. 01.143A.010.71e / Revision 1.00 2.4.3 Recall a Frequency from the User Memory To access the user memory frequency list, press MEM once, and select one of the 20 memory entries with the VOL/SEL turn knob. The selected memory entry is shown instead of the standby frequency. In the lower row of the display, the number of the memory entry selected is indicated by [MEM xx] (with xx = 1 to 20); if a name has been provided by the user for this memory entry, it is displayed next to the memory entry number.

With the tool the frequency memory of the ATR833A-II can be managed, i.e. frequencies can be added, edited and deleted. The frequency list can be stored as a file. The ATR Frequency Tool can be downloaded from the f.u.n.k.e. AVIONICS homepage in the service area under Info / Download.

Operation and Installation 17 Doc.-No. 01.143A.010.71e / Revision 1.00 2.5 Basic Settings To choose between the following settings, use the SET button: 1. VOL Volume (chosen by default) 2. SQL Squelch (noise suppression) 3. VOX Voice Activated Intercom (speech level required to activate the intercom) 4. INT Volume Intercom 5. STL Volume Sidetone left 6. STR Volume Sidetone right 7. EXT Volume of external audio signals 8. BRT Display brightness 9. CON Display contrast (only for devices with LCD) … back to Volume The return to the default display (VOL) is carried out by a short press on the Dualwatch button DW or happens automatically after 10 seconds of inactivity. The chosen setting can be adjusted by the VOL/SEL rotary knob. 2.5.1 VOL – Volume The radio returns automatically to the volume setting, when a value has been set with the VOL/SEL turn knob. Turning the VOL/SEL knob adjusts the volume of received radio signals. The higher the value, the louder the reception of radio signals. ACT 123.450 SBY 118.275 VOL 2 Range: 1 – 20 The VOL setting controls the volume of received radio signals only, not the volume of the intercom or the external audio input – these are set separately with INT and EXT.

Operation and Installation Doc.-No. 01.143A.010.71e / Revision 1.00 18 2.5.2 SQL – Squelch (noise barrier) By shortly pressing the SET key once, with the help of the rotary knob the squelch level can be adjusted. (Note: This is not related in any way to the intercom functionality.) This is a threshold that has to be exceeded by radio signal levels from other transmitters, in order to activate the reception circuitry. The higher the number, the stronger the radio signals have to be in order to be received. ACT 123.450 SBY 118.275 SQL 2 Range: 0 - 9 The setting for the squelch depends on different factors. For motor aircrafts an initial higher setting is typically appropriate, gliders may use a lower value. A lower number means higher input sensitivity. This allows reception of weaker signals (radio stations at higher distance), but can also result in pickup of own-aircraft radio interference sources (engine, strobe lights). 2.5.3 VOX –Voice Activated Intercom By shortly pressing the SET key twice, with the help of the rotary knob, the threshold volume VOX for intercom voice detection can be adjusted. (Note: This is not related in any way to radio reception or squelch.) VOX defines the crew’s speech volume that is required to activate the intercom functionality. The higher the value, the louder you need to speak in order to activate the intercom. Exception: VOX=OFF corresponds to “always on” The default squelch setting is 05. At higher values weak signals could be suppressed.

Operation and Installation 19 Doc.-No. 01.143A.010.71e / Revision 1.00 ACT 123.450 SBY 118.275 VOX 3 Range: Off, 1 - 9 In case of very noisy backgrounds or use of uncompensated microphones, the automatic VOX functionality may not work satisfyingly. In these cases, it is possible to deactivate the VOX automatism with VOX: 0, and to use an external intercom-switch. 2.5.4 INT – Volume Intercom By pressing three times the SET button, the volume of the intercom can be adjusted with the VOL/SEL turn knob. The intercom functionality is the onboard crew-internal communication for multi-seater aircraft. A change in the intercom volume level also changes the volume of the sidetone. The sidetone is an audible feedback of the own voice to the headset, i.e. you hear yourself speak. This feature supports a natural speech behavior. The intercom can be activated in two ways:  Automatically, i.e. whenever someone speaks into a microphone (i.e. voice activated intercom = VOX, see chapter 0).  Manually, i.e. by use of an external intercom switch. ACT 123.450 SBY 118.275 INT 3 Range: 0 – 20 2.5.5 STL – Volume Sidetone Left The sidetone is a self-hearing or back-hearing function during transmission. The audio signal picked up by the microphone is fed directly to the headset, which is normally perceived as pleasant. In this menu point the volume of the sidetone for the left seat can be adjusted.

Operation and Installation Doc.-No. 01.143A.010.71e / Revision 1.00 20 ACT 123.450 SBY 118.275 STL 4 Range: 0 - 20 2.5.6 STR – Volume Sidetone Right By pressing the SET button five times you get access to the STR menu. Here the volume of the sidetone for the right seat can be adjusted. ACT 123.450 SBY 118.275 STR 4 Range: 0 - 20 2.5.7 EXT – Volume of the external Audio Input By shortly pressing the SET key six times, the volume of external audio signals (warning tones, music, etc. …) can be controlled with the rotary knob. The higher the value, the higher is the volume of the external audio signal. A value of EXT = 0 deactivates the external audio input. ACT 123.450 SBY 118.275 EXT 5 Range: Off, 1 - 20 When no other device is connected to the external audio input, the input should be muted by selecting 00, in order to prevent noise by pickup of on-board interferences. The priority of the external audio input in comparison to radio receptions can be configured, see chapter 0)

Operation and Installation 21 Doc.-No. 01.143A.010.71e / Revision 1.00 2.5.8 BRT – Brightness By pressing the SET seven times the brightness of the backlight of the LCD display can be adjusted with the VOL/SEL turn knob. For devices with an OLED display this function controls the brightness of the display. ACT 123.450 SBY 118.275 BRT 5 Range: 0 - 9 2.6 Transmission By pushing the PTT button, the device starts transmission on the active frequency. The operation of the transmission is indicated by “TX” in front of the frequency used. ACT TX 123.450 SBY 118.275 VOL 5 In order to avoid unintended transmissions, e.g. when having the PTT button stuck (“stuck mic”), the transmitter automatically stops after 35 ±5 seconds of transmission and „Te“ is shown for 1 second. The unit returns to reception mode. ACT Te 123.450 SBY 118.275 VOL 5 In order to re-enable transmission in this case, release PTT and push it again. When having more than one PTT button and microphone equipped, it can be configured (chapter 0) to use only one PTT button for transmissions.

Operation and Installation Doc.-No. 01.143A.010.71e / Revision 1.00 22 2.7 Reception When receiving, a „RX“ is shown in front of the active frequency. ACT RX 123.450 SBY 118.275 VOL 5 When having dual watch active (see 0) RX can be shown on the standby frequency, too. ACT 123.450 DW RX 118.275 VOL 5 2.8 REPLAY Funktion The ATR833A-II automatically stores the last 9 seconds of an incoming radio call. Pressing the CURSOR key  will play the last received radio message. The display will show » R E P L A Y » for the duration of the playback. ACT 123.450 DW 118.275 VOL 5 ≫ R E P L A Y ≫ As long as a radio call is received, the REPLAY function is deactivated. This also means that the squelch setting must not be zero. 2.9 DUAL WATCH Operation The ATR833A-II comprises one receiver; therefore “dual watch” (simultaneously monitoring two frequencies) is implemented by alternating automatically between the active and the standby frequency. With dual watch mode active, basically the standby frequency is tuned in, shortly interrupted in regular intervals by tuning in the active frequency for a fraction of a second.

Operation and Installation 23 Doc.-No. 01.143A.010.71e / Revision 1.00 Every then detected radio signal on the active frequency has priority, and pauses the dual watch monitoring of the standby frequency, as long as the reception/transmission continues on the active frequency. Transmissions are always done one the active frequency. The dual watch mode is activated by pressing DW, and indicated by a changing the “SBY” label for the standby frequency to “DW”. ACT RX 123.450 DW 118.275 VOL 5 The dual watch mode is deactivated by pressing DW again, and by any operations changing either of the frequencies. In order to have an audible distinction between receptions on the active and the standby frequency, it is possible to hear the receptions from the standby frequency with a lower volume. Please refer to chapter 0. for information about the feature “dual watch volume reduction”. Quick approach:  Select or enter a standby frequency which shall be additionally monitored.  Set SQL with the SET button and the rotary knob to a value of at least 01.  Activate dual watch with DW (DW is shown) SQL has to be set to 01 at least, as without adequate squelch functionality the radio is not able to detect if there is a reception on the active frequency.

Operation and Installation Doc.-No. 01.143A.010.71e / Revision 1.00 24  As soon as no reception is determined on the active frequency, the mutual monitoring between active and standby frequency starts.  In order to deactivate dual watch: press DW once more or change the frequency. Don’t forget to interchange the active and standby frequencies, before answering a call on the standby frequency.

Operation and Installation 25 Doc.-No. 01.143A.010.71e / Revision 1.00 3 CONFIGURATION A very long press of SET (5 seconds) accesses the configuration menu. The configuration menu is used for fundamental settings. To choose between the following settings, use the SET button: 1. SPACING Channel spacing 2. DISPLAY Display darkening (power save mode) 3.

Operation and Installation 29 Doc.-No. 01.143A.010.71e / Revision 1.00 3.4 DUOWATCH – Dual-Watch Volume Reduction By shortly pressing the SET button four times, with help from the VOL/SEL rotary knob the lowering of the volume level (“mute”) for receptions on the standby frequency (when having dual watch active) can be controlled. This allows acoustic distinction between both frequencies. For further information about the dual watch mode see 2.8. ACT RX 123.450 SBY 118.275 DUOWATCH mute: -1 Wertebereich - 9 - 0 Minus 9 is the strongest reduction, i.e. the dual watch reception is much quieter. 0 means no reduction, i.e. the dual watch reception is as loud as the reception on the active frequency. 3.5 EXTAUDIO – Behavior of External Audio Input The external audio input can be used to feed a monaural audio signal to the amplifier for the headsets/speaker. An external audio signal can be used for different purposes. E.g. it is possible to check the audio signal of a VOR receiver, to attach a traffic sensor with acoustic output, or to use the external audio input for (monaural) music input. As these signals have different priorities in comparison to radio receptions, the priority of the external audio input can be configured. With the VOL/SEL rotary knob the following options can be selected: When deactivating one PTT button and microphone for transmissions, e.g. in order to keep passengers from interfering with ATC communication, don’t forget to reactivate the copilot’s PTT after end of the flight.

Operation and Installation Doc.-No. 01.143A.010.71e / Revision 1.00 30 ever on: The external audio input is always on, even during radio receptions and transmit mode. Use this setting only for very high priority acoustic warnings, e.g. collision warning beep tones. ACT 123.450 SBY 118.275 EXTAUDIO ever on auto off: The external audio input is automatically deactivated during transmit mode, or when no external audio activity is sensed. ACT 123.450 SBY 118.275 EXTAUDIO auto off not RXTX: The external audio input is automatically deactivated during radio receptions or transmit mode. This setting does not use the external audio activity sensing, and therefore can introduce noise when no signal source is connected. ACT 123.450 SBY 118.275 EXTAUDIO not RxTx A short press of SET switches to the next configuration item. Use this setting only when auto off does not react fast enough for very short external audio signals!

Operation and Installation 31 Doc.-No. 01.143A.010.71e / Revision 1.00 3.6 MIC TYPE – Selection Microphone Type The next option in the configuration menu is the setting of the microphone type. Selecting the microphone type switches the individual microphone inputs. With the setting "dynamic" the dynamic inputs MIC L dyn and MIC R dyn become active and the input for standard microphones is switched off. With the setting "standard" the inputs for standard microphones MIC L std. and MIC R std become active and the dynamic microphone inputs are deactivated. This avoids noise on unused inputs. With setting "auto", a standard microphone works on the standard input or a dynamic microphone on the dynamic input. If the dynamic microphone inputs are occupied, these are automatically activated and the standard inputs are switched off. If the dynamic microphones are deactivated via a switch, the standard microphone inputs are automatically activated.

ACT RX 123.450 SBY 118.275 HEAD OUT one The setting "one" is required when operating the transceiver with an old harness (without extension -S in the cable name). Adjusting the volume of the sidetone during transmission is then carried out via the menu item STL (Sidetone Level) and controls both headphones. The menu item STR is hidden. ACT RX 123.450 SBY 118.275 HEAD OUT two The setting "two" is required for the separate setting of the sidetone (STL and STR) of the headphones and requires the separate connection of two headphones. Cable sets with the extension "-S" provide this separate connection. 3.9 AUTO ON – Power-Up Behavior Under the menu item AUTO ON the switch-on behavior can be adjusted with the Avionic Master Switch. When "on" is set, the radio will start as soon as the operating voltage is supplied to the unit. ACT RX 123.450 SBY 118.275 AUTO ON on If "off" is set, the device remains switched off when the voltage is applied, no matter how switched off.

The maintenance shop can supply all cables. Suitable sets of cables are available from f.u.n.k.e. AVIONICS GmbH.  Select a position away from heat sources. Care for adequate convection cooling.  Leave sufficient space for the installation of cables and connectors.  Avoid sharp bends and wiring close to control cables.  Leave sufficient lead length for inspection or repair of the wiring of the connector.  Bend the harness at the rear connectors to inhibit water droplets (formed due to condensation) from collecting in the connector.  For mounting details/drawing refer to chapter 4.11.2 4.6 Equipment Connections One 25 pin D-SUB miniature connector includes all electrical connections, except for the antenna. 4.6.1 Microphone Connection The standard microphone inputs provide phantom power of 9V. The sensitivity can be set in the configuration menu (see chapter 3.7). Standard microphones (headset) and dynamic microphones (hand / gooseneck) can be connected at the same time. With setting MIC type auto, the dynamic microphone connection has priority over the standard microphone. The (+UB)-wire (PWR – Pin 11/12) has to be protected by a circuit breaker (4 Amp. slow-blow)!

Operation and Installation 39 Doc.-No. 01.143A.010.71e / Revision 1.00 4.6.2 Headset Connection Two headphones of the same type can be connected in parallel for each input. The total impedance in this case must not be less than 100Ω. 4.6.3 Audio-Input The external audio input can be used for the input of warn tones or music etc. In order to avoid disturbances while this input is not used, the respective wire needs to be short-circuited. With cable sets available from f.u.n.k.e. Avionics the external audio-input is already short-circuited by a blind plug. This blind plug can be easily removed in order to use the external audio input. If the external input is not used, it needs to be short-circuited with GND, in order to avoid the pickup of electrical noise. 4.7 Wiring 4.7.1 Conductor Cross Section The conductors used must be approved for aircraft installation.

He can be used e.g. for acoustic traffic warnings, for radio navigation receiver’s acoustic identifiers, or for input of music into the headsets. The priority of radio reception in relation to this input can be configured as described in chapter 0. 4.8 Antenna 4.8.1 Antenna Selection  A VHF-COM-Antenna with an impedance of 50 Ohm is required.  Choose an antenna type approved for the aircraft and the mounting location.  The antenna should be located far away from ELT-antennas and other VHF antennas.  Specified features depend on proper installation of the antenna.

Operation and Installation Doc.-No. 01.143A.010.71e / Revision 1.00 44 4.8.2 Installation Recommendation  Take note of the antenna manufacturer’s instructions.  The metallic contact between airplane surface and antenna-GND must be very good. On non-metallic airplanes a metal foil (min. 80 cm x 80 cm) shall be used as electrical counterweight on the inside of the belly.  To avoid a mutual interference of the radios, the antenna isolation between a voice transmission and a navigation antenna as well as between double COM antennas should be as large as possible. A distance of 2 meters usually is sufficient.  Assemble the antenna in vertical position so on or under the belly that it is as far distant as possible from all protruding parts (propeller, chassis, vertical stabilizer)  For glider installation the internal antenna installed by the manufacturer should be used.  The SWR shall not exceed 3:1. 4.9 Microphone / Intercom settings The settings of MIC and VOX values are essential for Intercom. The respective configuration options are described in chapter 0 (VOX=threshold level) and chapter 3.6 (MIC input sensitivity). If the VOX automatism is deactivated with VOX=OFF intercom is activated using the intercom switch (not PTT), which connects PIN 7 (intercom) of the equipment connector to GND. For operation with VOX activated PIN 7 has to be connected to GND permanently. Transmission merely operates when PTT is pressed. The suppression of background noise is only possible using differential microphones, as they are usual with modern headsets. Normal electret microphones are not suitable. The HF antenna wire must not be included in any other cable sets, for example power supply or microphone. It must also not be placed together with other antenna wires, for example NAV or Transponder.

Operation and Installation 45 Doc.-No. 01.143A.010.71e / Revision 1.00 4.10 Post-Installation Check When installation is completed all steering and control functions of the aircraft are to be examined, in order to exclude disturbances by the wiring. The SWR shall not exceed 3:1. Furthermore a test flight is recommended, in order to guarantee the proper in-flight operation of the radio:  In a flight altitude of at least 2000 ft contact a ground station in a distance of at least 50 km (30 nautical miles).  Pay attention to unusual electrical interference.  If possible, perform the radio test on frequencies within the upper and lower VHF communication frequency range A certified maintenance shop must verify proper operation of the VHF Transceiver System.
