between aircraft and ground using the very high frequency band between
118.000...136.9750 MHz with a selectable channel spacing of 25 kHz respectively
8.33 kHz.
Several functions and settings are only available via the
password-protected "Configuration Settings*".
* For details please refer to manual:
http://www.becker-avionics.com/downloads/ → AR620X Family.
For further descriptions we are using following terms for VHF transceivers instead
writing their complete model number.

Device Description
• The figures for illustrating display show transceivers working in
8.33/25 kHz mixed mode.
• Dedicated pictures for 25 kHz mode are not explicitly shown
(they differ only in number of digits for frequency).
• The HMI actions described in this section can be performed

Operating Instructions
Device Description
2.1.5. Safety-Conscious Utilization
Excessive pulses on the DC bus of the aircraft may cause
damage on electrical circuits of any installed instrument.
Do not switch ON the device during engine start or
shutdown.
A voice communication test shall be performed before
starting the engine.
It should be noted that, if the communication test is carried
out close to a ground station, the results may be positive
even if the antenna cable is broken or short-circuited. In
such a case, at a distance of 5 to 10 km and above,
communication might not be possible.
•
Speak always loud, clear and not too fast for optimal voice
communication.
•
Keep the microphone always close to the lips otherwise a special
suppressing circuit in the VHF COM will not be capable to suppress
normal cabin noise.
•
Use only microphones or headsets which are suitable for use in an
aircraft.
o
In aircraft made of wood, synthetic materials or in gliders or
helicopters, incoming radiation can affect the integrated amplifier of
the microphone (feedback), noticeable in the ground station by
whistling and/or heavy distortion.
If the power supply voltage drops below the "Low Battery Threshold" (default value is
10.5 V), the "LOW BATTERY" message will appear each 3 seconds in the lower part
of the display.
If the power supply voltage drops below 10 V the system
enters power saving mode:
• Speaker output of the transceiver is automatically
switched "OFF"
• Speaker sign will no longer be presented on LCD display
• The pilot must use headphones to continue listening.
Channels store/change:
• The functions "LAST" and Store/Restore are only
available if they are activated in "Configuration Settings*"
- ("MEM OPTIONS").
* For details please refer to manual:
http://www.becker-avionics.com/downloads/ → AR620X Family.

2.9.
Auxiliary Audio Input (AUX)
The transceiver has a dedicated auxiliary audio input e.g. for MP3 player connection.
This function can be enabled in the "Configuration Settings*".
With auxiliary input enabled, the auxiliary audio input signal will be mixed with the
received signal from antenna (passing squelch) and the intercom signal (when
activated).
When intercom operates in ISOLATION mode, auxiliary audio input signal is audible
on headphone 2 output, even if radio communication (transmission/receiving) is
active.
AUX AUTO MUTE function depends on the AUX INPUT, selectable via the
"Configuration Settings*". This function automatically mutes the audio signal from the
auxiliary audio input as long as the device detects (based on squelch evaluation) a
RX signal or the user deactivates the squelch manually. If this function is disabled the
signal from the auxiliary audio input is permanently audible on the audio output,
independently of the received signal or the squelch status.
Automatic AUX attenuation functionality controls the auxiliary audio input. The level
of the auxiliary input signal attenuates if intercom is activated by VOX or by IC
discrete input. The auxiliary input signal reverts to its previous value after intercom
deactivation.
The attenuation value can be adjusted within the range from 0...40 dB.

• If intercom operation is active, the "IC" sign appears in the
display.
127.000
The setting of VOX-threshold and intercom volume is accessible in the intercom
menu. In tandem configuration (application with additional controller) it is only
possible on primary controller.
•
•
For the AR620X single block devices, the primary controller is the one
directly connected to the device.
For the RT6201 remote device the primary controller is the one
connected to primary control interface.
VOX-threshold and intercom volume for the second intercom circuit are adjustable
from secondary controller RCU6201 (secondary controller is the one connected to
secondary control interface).
The transceiver has two internal built in intercom circuits. Therefore, up to four
headsets are connectable.
•
•
Pilot and co-pilot connect to the first intercom circuit.
o
When intercom is active, both microphone signals are mixed and
amplified and will be audible on both headphone outputs. This
enables internal communication via headsets between both pilots.
Passenger headsets are connecting to the second intercom circuit.
ALL-mode - Everyone connected to the intercom will hear all communications (pilots
hear passengers and passengers hear pilots).
ISOL-mode - Provides separate intercoms for the pilots (intercom circuit 1) and the
passengers (intercom circuit 2).
This allows pilots to communicate with each other and air traffic, while the
passengers are isolated. The passengers on the intercom circuit 2 can hear auxiliary
audio (for example from MP3 player) and can communicate with each other.
An external "ISOL" input provides possibility to switch between ALL mode and
ISOL mode. If the PTT1 input is active and ISOL is active the passenger intercom
operation on second intercom circuit is still possible.

• In tandem installation the second controller RCU6201 adjusts
VOX threshold for second intercom circuit.
Note:
At a setting for VOX threshold of -15 a convenient behaviour of
the VOX should be achieved in most aircraft. This requires that
mike sensitivity had been correct adjusted (Configuration
Settings*). If the mike sensitivity is not correct adjusted, VOX
may not work satisfying.

Description
"LOW BATT”: the supply voltage of the transceiver is below the
defined threshold.
The transceiver is still operable but may have a reduced
performance depending on supply voltage.
Possible reasons for indication:
• Accumulator capacity problems (gliders).
• Power interrupts.
• General power supply problems.
• Setting for low battery threshold too high.
"STUCK PTT”: is indicated after 120 seconds of continued
transmission. The transceiver goes back to receive mode even
if the PTT line is still active (GND).
For initiating a new transmission, the PTT line needs first to
become inactive (open).
Possible reasons for indication:
• Transmission lasts more than 120 seconds.
• PTT-key is stuck.
• PTT line permanently grounded (short circuit in installation).
"TX HOT”: is indicated if the internal device temperature
exceeds +90 °C.
Transceiver is still operable. Performance of transmitter is
reduced.
Possible reasons for indication:
• Very hot environmental temperature, long transmission
times and insufficient airflow conditions
The transceiver has detected an internal failure during normal
operation.
Depending on failure reason, the device may still be operable
with degraded performance or not operable at all.
Possible reasons for indication:
• Specified environmental conditions
• HW or SW failure inside the transceiver.
