AUDIO PANEL AND CNS

4.5 ADDITIONAL AUDIO PANEL FUNCTIONS

POWER-UP

The Audio Panel performs a self-test during power-up. During the self-test all Audio Panel annunciator lights
illuminate for approximately two seconds. Once the self-test is completed, most of the settings are restored to
those in use before the unit was last turned off.

MONO/STEREO HEADSETS

Stereo headsets are recommended for use with the G900X.
Using a monaural headset in a stereo jack shorts the right headset channel output to ground. While this does
not damage the Audio Panel, a person listening on a monaural headset hears only the left channel in both ears.
If a monaural headset is used at one of the passenger positions, any other passenger using a stereo headset hears
audio in the left ear only.

SPEAKER

All of the radios can be heard over the cabin speaker (if installed). Pressing the SPKR Key selects and
deselects the cabin speaker. Speaker audio is muted when the PTT is pressed. Certain aural alerts and warnings
(autopilot, traffic, altitude) are always heard on the speaker, even when the speaker is not selected.
The speaker volume is adjustable within a nominal range. Contact a Garmin-authorized service center for
volume adjustment.
