INTERCOM
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 HAIL Key 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 hail 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).
