Nav/Com Tuning; Intercom; Passenger Address (Pa) System - Garmin G1000 Reference Manual

NAV/COM TUNING

1) Press the small tuning knob to select the desired radio for tuning. A light
blue box highlights the radio frequency to be tuned.
2) Turn the respective tuning knobs to enter the desired frequency into the
standby frequency field. The large knob enters MHz and the small knob
enters kHz.
3) Press the Frequency Transfer Key to place the frequency into the active
frequency field.

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.
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.
During manual squelch operation, pressing the ICS Knob switches between volume
and squelch adjustment, lighting the associated annunciator beneath the knob. When
the MAN SQ annunciator is lit, the ICS Knob controls both volume and squelch. When
the MAN SQ annunciator is extinguished, the ICS Knob controls only volume.

PASSENGER ADDRESS (PA) SYSTEM

A passenger address system is provided by pressing the PA Key to deliver messages
to the passengers. The message is heard by the other pilot on the headset only if the
PA Key is enabled on both audio panels. PA messages are one way from the flight deck
to the passengers.
