INTERCOM VOLUME AND SQUELCH
Two volume controls, one for the pilot and a combined copilot/passenger control, set intercom audio
level.
Each microphone input has an automatic squelch threshold. Manual squelch is available by pressing the
Pilot side VOL/SQ knob. When the MAN SQ annunciation is lit the large squelch knobs control pilot and
copilot/passenger squelch threshold. Turning either knob clockwise increases the squelch threshold level.
Turning either knob counterclockwise decreases the squelch threshold level.
When the MAN SQ annunciation is not lit, squelch is automatic and the large squelch knobs have no
function.
