COM Audio Selector (3)
Communication audio from the other radio, not selected for transmit, can be
heard by pressing the associated RCV button. You will always hear the au-
dio from the selected transceiver.
In SPLIT mode, only the pilot will hear selected navigation audio (A1 &

The users can identify which receivers are selected by noting which green

Any other installed receiver audio (Marker, ADF, etc) is interfaced through
an unswitched input.
