Operation and Installation 12 Document-No.: 01.1403.010.71e / Revision: 3.01 2.4.1 VOL - Volume Can be reached by a long press of the SET button, but is also automatically chosen by the radio after 12 seconds of user inactivity. Adjusts the volume of received radio signals by turning the knob. The higher the value, the louder the reception of radio signals. ACT 123.450 SBY 118.910 VOL 03 2.4.2 SQL - Squelch 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 118.910 SQL 07 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). 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 . Range: 01 – 16 Range: 01 - 10

Operation and Installation 13 Document-No.: 01.1403.010.71e / Revision: 3.01 2.4.3 DIM – Display Brightness By shortly pressing the SET key twice, with help from the rotary knob the display’s illumination can be adjusted. ACT 123.450 SBY 118.910 DIM 08 2.4.4 VOX – Voice Detection (Speech Threshold for Voice Activated Intercom) By shortly pressing the SET key three times, 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 01 corresponds to “always on” The internal filter circuitry has the ability to distinguish between engine noise and speech. ACT 123.450 SBY 118.910 VOX 05 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 01, and to use an external intercom-switch. The default Squelch setting is 05. At higher values, weak signals could be suppressed. Range: 01 – 10 Range: 01 – 10

Operation and Installation 14 Document-No.: 01.1403.010.71e / Revision: 3.01 2.4.5 DWM – Dual Watch Volume Reduction By shortly pressing the SET key four times, with help from the 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 2.6. ACT 123.450 SBY 118.910 DWM -2 2.4.6 INT - Intercom-Volume The intercom functionality is the onboard crew-internal communication for multiseater aircraft. By shortly pressing the SET key five times, the intercom volume level can be controlled by the rotary knob. The higher the value, the higher the intercom volume. 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 behaviour. The intercom can be activated in two ways: • Automatically, i.e. whenever someone speaks into a microphone (i.e. voice activated intercom = VOX, see 2.4.4). • Manually, i.e. by use of an external intercom switch (cable overview see 4.7.3.1). ACT 123.450 SBY 118.910 INT 03 Range: -8 – 00 -8 is highest muting (dual watch reception at much lower volume) 00 is no muting (dual watch reception at same volume) Range: 01 – 10

Operation and Installation 15 Document-No.: 01.1403.010.71e / Revision: 3.01 2.4.7 EXT - Volume of the External Audio Input By shortly pressing the SET key six times, with help from the rotary knob, the volume from the connected external audio signals (Warning tones, music, etc…) can be set. The higher the value, the higher the volume of the external audio signal. A value of 00 deactivates the external audio input. ACT 123.450 SBY 118.910 EXT 03 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 3.4. Range: 00 - 10

Operation and Installation 16 Document-No.: 01.1403.010.71e / Revision: 3.01 2.5 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 ▲▼ . Entering a new standby frequency can be done by a) manual input, b) recall of previously stored frequencies from the user memory, or c) recall from the list of the last 10 used frequencies. 2.5.1 Automatic 8.33 / 25 kHz Channel Width Selection 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 standardised 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 25kHz-only radios. To use the same frequencies with 8.33kHz 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. 2.5.2 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 rotary knob. The selected part of the frequency is marked with the underline. ▲▼ interchanges the newly set standby frequency and the former active frequency.

Operation and Installation 17 Document-No.: 01.1403.010.71e / Revision: 3.01 When having the channel selection configured for 8.33 kHz steps (see 3.1), the frequency is input in three steps: 123.450 → 123.450 → 123.450 When having the channel selection configured for allowing 25 kHz channels only (see 3.1), the frequency is input in two steps: 123.450 ↔ 123.450 2.5.3 Recall a Frequency from the User Memory To access the user memory frequency list, press MEM once, and select one of the 100 memory entries with the turn knob. The selected memory entry substitutes the former standby frequency. In the lower row of the display, the number of the memory entry selected is indicated by [MEM xx] (with xx = 00 … 99); if a name has been provided by the user for this memory entry, it is displayed next to the memory entry number. ACT 123.450 SBY 121.270 MEM 17 HAMBURG ▲▼ interchanges the newly set standby frequency and the former active frequency, and leaves the memory list menu. If no input is done for 12 Seconds, the device returns to the standard view, too. 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. Entry number (Range: 00 – 99)

Operation and Installation 18 Document-No.: 01.1403.010.71e / Revision: 3.01 2.5.4 Recall a Frequency from the List of the 10 Last Used The radio automatically keeps track of the last 10 used active frequencies. To access this list, press MEM twice, and select one of the 10 list entries with the turn knob. The selected memory entry substitutes the former standby frequency. The number of the selected list entry is given in the display’s lower row. ACT 123.450 SBY 118.700 LST 01 Key ▲▼ interchanges the newly set standby frequency and the former active frequency, and leaves the last used list menu. If no input is done for 12 Seconds, the device returns to the standard view. 2.5.5 Store a Frequency into the User Memory The active frequency can be stored into any entry of the user memory. This is achieved by a long press on MEM when having the user memory entry to be overwritten selected. The following example stores the frequency 124.350 MHz of KONSTANZ into the user memory entry 07: List entry „00“ contains the last standby frequency from the MEM menu. Entry number (Range: 00 – 10)

Enter the name • by changing the selected character with , and advancing the selection with ► , just as when manually entering a standby frequency. ACT 124.350 SBY 124.350 MEM 07 KONSTANZ 7. Store the name • either with a long press of MEM , • or with a long press of ► . ACT 124.350 SBY 124.350 MEM 07 KONSTANZ You can now leave the user memory access by pressing MEM twice or by waiting for the timeout (12 seconds). 2.6 Dual Watch Operation The ATR833 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. 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 123.450 DW 135.700 VOL 05 The dual watch mode is deactivated by pressing DW again, and by any operations changing either of the frequencies.

Operation and Installation 21 Document-No.: 01.1403.010.71e / Revision: 3.01 In order to have an audible distinction between receptions on the active and the standby frequency, it is possible to receive the receptions from the standby frequency with a lower volume. Please refer to chapter 2.4.5 for information onto this feature “dual watch volume reduction”. Quick approach: • Select or enter a standby frequency which shall be additionally monitored. • Set SQL with the SET key and the rotary knob to a value of at least 02. • Activate dual watch with DW (DW is shown) • 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. SQL has to be set to 02 at least, as without proper squelch functionality the radio would not be able to detect whether on the active frequency a reception takes place. Don’t forget to interchange the active and standby frequencies, before answering a call on the standby frequency. Using dual-watch requires switching between the active and the standby frequency. Therefore it may happen that calls on the active frequency cannot be monitored completely. As the result we recommend not to use dual-watch in airspaces where listening watch is required.

Operation and Installation 22 Document-No.: 01.1403.010.71e / Revision: 3.01 2.7 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 135.700 VOL 05 In order to avoid unintended transmissions, e.g. when having the PTT button stuck (“stuck mic”), the transmitter automatically stops after two minutes of transmission, and „TX“ is substituted by „Te“. In order to re-enable transmission in this case, release PTT and push it again. 2.8 Reception When receiving, a „RX“ is shown in front of the active frequency. When having dual watch active (see 2.6) this can be on the standby frequency, too. ACT RX 123.450 SBY 135.700 VOL 05 ACT 123.450 DW RX 135.700 VOL 05 When having more than one PTT button and microphone equipped, it can be configured (chapter 3.3) to use only one PTT button for transmissions.

Operation and Installation 23 Document-No.: 01.1403.010.71e / Revision: 3.01 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. SPC ..... Channel spacing 2. DPY ..... Automatic display darkening 3. PTT ...... PTT key selection 4. EXT ...... Behavior of the external audio input 5. MLS ..... Sensitivity of the left standard microphone input 6. MLD ..... Sensitivity of the left dynamic microphone input 7. MRS ..... Sensitivity of the right standard microphone input 8. MRD .... Sensitivity of the right dynamic microphone input 9. TST ...... Activation/deactivation of the test mode (for maintenance) …. Leaving configuration menu / back to VOL (can also be reached by long press of SET ) The chosen setting can be adjusted by the rotary knob. 3.1 SPC – Channel Spacing With this setting, the ATR833 can be configured to constrain frequency selection to 25 kHz channels only. This can be used to speed up the manual frequency input in areas where no 8.33 kHz channel spacing is used. See chapter 2.5.2 on further information on manual frequency input. ACT 123.450 SBY 118.910 SPC 8.33 kHz With the rotary knob the following options can be selected: 8.33 kHz Allows input of both 8.33 kHz and 25 kHz channels 25 kHz Allows input of 25 kHz channels only. A short press of SET switches to the next configuration item, a long press of SET exits the configuration menu.

Operation and Installation 24 Document-No.: 01.1403.010.71e / Revision: 3.01 3.2 DPY – Energy Saving Mode (Aut. Display Darkening) In order to save energy – and to extend the lifetime of the OLED display – an automatic display darkening can be configured. ACT 123.450 SBY 118.910 DPY always on With the rotary knob the following options can be selected: always on No display darkening at all xx min off Automatic darkening after xx minutes of user inactivity (xx = range 1–30) Reactivation of the darkened display is done by press of any key (except key I/O ) or turn of any knob (the action of the key pressed is performed when pressing the key again after the display turned on) or when transmitting. A short press of SET switches to the next configuration item, a long press of SET exits the configuration menu. This configuration item is not used for determining whether a specific frequency is used with 8.33 kHz or 25 kHz channel width, as this is done by the ATR833 automatically depending onto the frequency value entered. For more details see chapters 2.5.1 and 5.1. Please keep in mind to enable 8.33 kHz channel selection before flying into areas where 8.33 kHz channels are used.

ACT 123.450 SBY 118.910 PTT all mics With the rotary knob the following options can be selected: all mics Both PTT buttons and all microphones are used for transmissions, no matter what PTT button was pressed single mic According to the PTT button pressed, the associated microphone is activated left only Only the left PTT button and the left microphone(s) are used for transmissions right only Only the right PTT button and the right microphone(s) are used for transmissions The intercom functionality is not affected by this setting. A short press of SET switches to the next configuration item, a long press of SET exits the configuration menu. This feature should only be used when • it can be foreseen that no frequency changes will be required (i.e. when using only limited airspace near one airport, e.g. for circuit pattern training flights), and • the crew is familiar with the energy saving mode. In all other cases this feature shall be deactivated, in order to prevent the usage of wrong frequencies and to avoid confusion of pilots not aware of the energy saving mode.

Operation and Installation 26 Document-No.: 01.1403.010.71e / Revision: 3.01 3.4 EXT – External Audio Input’s Behavior 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 rotary knob the following options can be selected: always 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. auto off The external audio input is automatically deactivated during transmit mode, or when no external audio activity is sensed. 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. 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. ACT 123.450 SBY 118.910 EXT auto off Use this setting only when auto off does not react fast enough for very short external audio signals!

Operation and Installation 32 Document-No.: 01.1403.010.71e / Revision: 3.01 4.6 Equipment Connections One 25 pin D-SUB miniature connector includes all electrical connections, except for the antenna. 4.6.1 Microphone-Connection Microphone Input Left Right Standard (headset) MLS MRS Dynamic (glider’s gooseneck microphone) MLD MRD The inputs for standard microphones are appropriate for input voltages of 50 mVpp to 2 Vpp. These inputs have a bias voltage of 8 V at 330 ohms. Sensitivity is adjustable in the configuration menu (see 3.5). The inputs for dynamic microphones are appropriate for input voltages of 5 mVpp to 10 mVpp. These inputs have no bias. In general standard microphones (headsets) MLS/MRS and dynamic microphones (hand/gooseneck) MLD/MRD can be used simultaneously. In motor gliders, when the engine is running, the dynamic microphones should be turned off (switch MLD/MRD inputs to GND), in order to avoid the transmission of the engine’s noise. If no dynamic microphone is installed, the input sensitivity for MLD/MRD shall be set to 1 (see 3.5). Per input, up to two microphones can be connected in parallel. The (+UB)-wire has to protected by circuit breaker (4 Amp. slow-blow)! Unused microphone inputs should be short-circuited.

Operation and Installation 33 Document-No.: 01.1403.010.71e / Revision: 3.01 4.6.2 Headset-Connection Headphones may be connected parallel, as long as the total impedance doesn’t fall below 8 Ohm. 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 GmbH 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. 4.6.4 Remote Control Panel In tandem-seated aircrafts it is possible to control the ATR833 by a remote control panel (ATR600RT Remote Control Unit). The choice of the remote control depends onto the software version of the ATR833: Version up to SW V6.3 are remote controlled by the ATR600RT with 4-knob interface. Versions starting from SW V6.4 on are remote controlled by the ATR600RT with 2-knob interface. If you use a ATR600RT with 4-knob-interface, please indicate in case of repairs and software updates that no SW version larger than V6.3 may be installed!

MSTR = Master Radio Connector for the Remote Control in the cable harness BSKS833S/D View from aircraft’s side 4.7.3.3 Connector EXT-NF for Monaural Audio Input This connector is used for the input of monaural audio signals. 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 section 3.4. 4.7.3.4 Auto-ON Connector pin 20 determines the radio’s behaviour when applying power: To activate the radio in aircraft with a dedicated avionic master switch by this master (i.e. by applying power to the radio), connect pin 20 to the avionic master additionally to pins 11 and 12; in this case, the radio’s on/off-key has no functionality. In aircraft without a dedicated avionic master, pin 20 is left open; in these case, the radio’s on/off-key is used.

Operation and Installation 38 Document-No.: 01.1403.010.71e / Revision: 3.01 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. 4.8.2 Antenna Cable The antenna is connected by a 50 Ohm coaxial cable. The connection to the radio requires a male BNC connector. 4.8.3 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. The cable length, the attenuation of the selected cable and the quality of the connections has a direct effect on the transmitted power at the antenna. For support please contact your maintenance organization.

Operation and Installation 39 Document-No.: 01.1403.010.71e / Revision: 3.01 • 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 sections 3.5 (MIC=Microphone level) and 2.4.4 (VOX=threshold level) If the VOX automatism is deactivated with VOX=01 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. 4.10 Post-Installation Check 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. A certified maintenance shop must verify proper operation of the VHF Transceiver System.

Operation and Installation 40 Document-No.: 01.1403.010.71e / Revision: 3.01 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 4.11 Drawings 4.11.1 Dimensions 4.11.2 Mounting Advices For mounting in panel with a thickness of 3-5 mm longer screws are available (Order- No. ZUB5). 65 mm 168 mm 20 mm 65 mm 18 mm
