Page 4: Operation
AR6201 Section 3 OPERATION Note: In this section the display content is mainly shown for transceiver working in 8.33+25 kHz mixed Mode. Dedicated pictures for 25 kHz Mode are not explicitly shown, because the display content is very similar (They differ only in number of digits for frequency. -
Page 5: Controls
AR6201 3.2.1 Controls Symbol Description Main Function IC/SQL ”Short press” during normal operation toggles squelch ON/OFF state. (Intercom/Squelc “Long press” during normal operation activates IC menu. “Short press” during normal operation changes the frequency selection mode. (Mode) “Long press” during normal operation activates the pilots menu. -

AR6201 Start–Up CAUTION: Do not switch ON the VHF transceiver when engines are being started or shut down. Note: Excessive pulses on the DC bus of the aircraft may cause damage on electrical circuits of any installed instrument. a. Switch ON the VHF transceiver by turning the volume knob. b. -
Page 7: Channel Spacing Mode
AR6201 Channel Spacing Mode The channel spacing in which the transceiver shall work can be toggled by pressing by pressing “STO” and “MDE” keys simultaneously for at least 2 seconds. 8.33 kHz channel spacing (left) / 25 kHz channel spacing (right) This toggling of channel spacing mode is only available for AR6201-(0XX) variants. -

Page 9: Operation Modes
AR6201 During TX operation, the sidetone (demodulated audio of the emitted signal) is available on the headphone output. The speaker is switched off. Note: Transmit operation will automatically be terminated (return to receive operation) after 120 seconds of continuous transmitting even if PTT is still pressed. In this case “STUCK PTT”... -
Page 10: Direct Tune Mode
AR6201 3.6.2 Direct Tune Mode Direct tune mode can be entered by consecutive short pressing of “MDE”. Direct tune mode will be leaved by selecting another operation mode. In direct tune mode the active frequency is indicated in the top line. The battery voltage is indicated in the bottom line. -
Page 11: Scan Mode
AR6201 3.6.4 Scan Mode The Scan mode can be entered from all frequency selection modes by a long press of “↕/SCN” key. The Scan mode can be left by a short press of the “MDE” key. After leaving scan mode, device will enter the standard mode. -
Page 12: Storage Function
AR6201 If the squelch function is active (on), noisy signals will be muted. The threshold for the squelch can be adjusted in the pilots menu. Storage Function The transceiver has two kind of storage functions implemented: - Manual storing of frequencies - Automatically storing of frequencies 3.8.1 Manual Storage Function... -
Page 13: Intercom Operation
AR6201 transceiver is in receive operation. If disabled, the audio signals applied on this input will be ignored. Furthermore in installation setup can also be enabled/disabled a so called “auto aux mute function”. If this function is enabled the audio signal from the auxiliary audio input will be muted automatically, when the transceiver detects (based on squelch evaluation) a received antenna signal or user deactivate squelch manually. -
Page 14: Menus
AR6201 Speaker output will be switched off even if speaker is enabled in following cases: - Transceiver is in transmit operation. - Intercom was activated by external intercom switch. - Power supply is below 10 Volt. 3.12 Menus During normal operation in one of the four operation modes above the following menus can be entered: - IC menu for adjustment of intercom volume and VOX threshold. -
Page 15: Pilots Menu
AR6201 An adjustment of the VOX threshold level is not possible if the VOX is forced off (due to enabled speaker). VOX can be switched off by turning the VOX threshold level “above” +10. In this case the display will show: When VOX is switched off, the intercom operation may still be activated by the external intercom switch. -
