3.1 .1
INTERCOM KEYING MODE AND SENSITIVITY SELECTOR
This adjustment selects VOX mode ON or OFF. In the ON mode, the audio produced by any of
the microphones will break the squelch of the intercom and will be routed through the intercom
system. The threshold audio level required to break the squelch is also adjustable by this knob.
A setting of fully clockwise on the knob will leave the intercom keyed at all times. When set
to OFF (fully counterclockwise), the intercom will only receive audio when intercom PTT is
keyed.

Receivers - independant of the setting of the Transceiver SELECTOR
