ATR833S / P/N 833S-(Cxxx)-(Cxxx)
Operation and Installation
Cable sets available from f.u.n.k.e. AVIONICS already have the external
audio-input short-circuited with 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 Operation with Cable Adapter

If the radio is connected to a pre-installed cable set via a cable adapter,
both headphones are connected to the left headphone output.
In this case a separate sidetone setting is not possible. The device
automatically detects the cable adapter and adjusts the settings in the
standard menu accordingly.
The menu item STR is omitted and via STL the sidetone can be set in
transmit mode for both headphone connections.
The INT menu item controls the intercom volume for both headphones.
