PM2Crew Expansion module (11918)

Section III OPERATION
Switching on the intercom or PMA4000 automatically activates the PM2CREW unit. .
3.1 Adjusting The Volume
The volume control and squelch controls only affect the headsets connected to the PM2CREW directly,
and not the main unit.
3.2 Adjusting The Squelch Control
The PM2CREW provides individual VOX circuits for passenger 1, passenger 2, and another for
passengers’ three and four. With the engine running, set the squelch control knob by slowly rotating the
squelch control knob clockwise until you no longer hear the background noise in the earphones. When the
microphone is positioned properly near the lips, normal speech levels should open the channel. When you
have stopped talking, there is a delay of about one-second before the channel closes. This prevents squelch
closure between words, and helps eliminate choppy intercom conversation.
