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.
When intercom is active, both microphone signals are mixed and
o
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.

• If intercom operation is active, the "IC" sign appears in the
display.
