Pressing the INTR COM Key on either Audio Panel selects and deselects the intercom on both Audio Panels.  

The annunciator is lit when the intercom is active.  The intercom connects the pilot and copilot together.  Either 
the pilot or copilot may select or deselect the intercom.

The CABIN Key initiates two way communication between the pilot or copilot and the passengers in the 

cabin.  The annunciator is lit when the cabin intercom is active on either Audio Panel.

When the flight crew wants to communicate with the passengers, the pilot or copilot presses the CABIN 

Key to signal that communication is desired.  The cabin signal must be acknowledged to begin intercom 
conversation.

When the passengers want to communicate with the pilot/copilot, they press the “COCKPIT CALL” switch

at their seat in the cabin. The CABIN annunciator flashes on both Audio Panels to signal the pilot and copilot
that cabin communication is desired.  The cockpit call signal must be acknowledged by pressing the CABIN 
Key to begin intercom conversation.

The MAN SQ Key allows either automatic or manual control of the intercom squelch setting.  Pressing the 

MAN SQ Key enables manual squelch control, indicated by the MAN SQ annunciator.

• When the MAN SQ Annunciator is extinguished (Automatic Squelch is on), the ICS Knob controls only the 

volume  (pressing the ICS Knob has no effect on the VOL/SQ selection).

• When the MAN SQ Annunciator is illuminated (Manual Squelch), the ICS Knob controls either volume or 

squelch (selected by pressing the ICS Knob and indicated by the VOL or SQ annunciation).
