The transceiver provides with pin 7 connected to ground intercom
operation. This input has an internal pull up and is LO active at
max.1 mA. For installations where automatic intercom operation is
activated via VOX connection of this pin 7 is not necessary.
This discrete input activates intercom:
• when VOX does not work satisfactorily because of too high ambient
noise in the cockpit,
• or speaker is “enabled” in current audio in/out configuration
(Installation Setup).
