Selecting A Nav Radio; Nav/Com Tuning; Intercom System (Ics) Isolation - Garmin G1000 Reference Manual

SELECTING A NAV RADIO

1) To begin navigating using a navigation radio, press the CDI Softkey on the
PFD to select VOR1/LOC1 (NAV1) or VOR2/LOC2 (NAV2).
2) Press the NAV1 , NAV2 , DME , or ADF Key on the audio panel to select or
deselect the navigation radio audio source. All radio keys can be selected
individually or together.

NAV/COM TUNING

1) 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.
2) Press the appropriate Frequency Transfer Key to place the frequency into
the active frequency field.

INTERCOM SYSTEM (ICS) ISOLATION

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 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).
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 cockpit speaker
(if selected on) or on the headset if the PA Key is selected on both audio panels. PA
messages are one way from the flight deck to the passengers.
