PAC45 Pilot Guide
NOTE: Mono headsets that short the tip and ring (i.e. older models) will
introduce some audio distortion when used. Modern, stereo headsets are
recommended in all positions.
Intercom Modes
The “ICS” pushbutton switch on the panel provides
the selection of the intercom modes
The intercom mode defaults to “ALL” at power up. Then the button cycles
through the intercom modes, from top to bottom, then bottom to top as:
ISO, ALL CRW and CRW, ALL, ISO. A green indicator shows which
mode is currently active.
ISO: The pilot or copilot that has selected ISO is isolated fr om the in-
tercom and is connected only to the aircraft radio system. He will hear the
aircraft radio reception (and sidetone during radio transmissions). The other
crew member (unless they have also selected ISO) and passengers will have
radios, intercom and music.
ALL: All par ties will hear the air cr aft r adio, inter com and music.
During any radio or intercom communications, the music volume automati-

level after communications have been completed.
Crew (CRW): Pilot and copilot ar e connected on one inter com channel
and have exclusive access to the aircraft radios. The passengers will be able
to talk to each other.
In addition, the following rules apply:
System defaults to ALL-ALL at power up.
Either panel can select ISO, and be removed from intercom, while
the other remains with the passengers.
Either panel can select CRW, and place both panels in Crew mode
Either panel can select ALL and add everybody to the intercom
and radio
