Passenger Address (Pa) System - Garmin G900X Pilot's Manual

AUDIO PANEL AND CNS
INTERCOM VOLUME AND SQUELCH
The PILOT/PASS Knob controls volume or manual squelch adjustment for the pilot and copilot/passenger.
The small knob controls the pilot volume and squelch. The large knob controls the copilot/passenger volume
and squelch. The VOL and SQ annunciations at the bottom of the unit indicate which function the knob is
controlling. Pressing the PILOT/PASS Knob switches between volume and squelch control as indicated by
the VOL or SQ annunciation being illuminated.
The MAN SQ Key allows either automatic or manual control of the squelch setting. When the MAN SQ
Annunciator is extinguished (Automatic-Squelch is on), the PILOT/PASS Knob controls only the volume
(pressing the PILOT/PASS Knob has no effect on the VOL/SQ selection).
When the MAN SQ Annunciator is illuminated (Manual Squelch), the PILOT/PASS Knob controls both
volume and squelch.

PASSENGER ADDRESS (PA) SYSTEM

A passenger address system is available for delivering voice messages over the cabin speaker. When the PA
Key is selected on the Audio Panel, the COM MIC Annunciator is extinguished, and the active COM frequency
changes to white, indicating that there is no COM selected. A Push-to-Talk (PTT) must be pressed to deliver PA
announcements. The PA Annunciator flashes about once per second while the PTT is depressed.
