AUDIO PANEL AND CNS
4.5 ADDITIONAL AUDIO PANEL FUNCTIONS
POWER-UP
The Audio Panels perform 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. The exceptions are the speaker and intercom, which are always
selected during power up.
MONO/STEREO HEADSETS
Stereo headsets are recommended for use in this aircraft.
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
Each Audio Panel controls a separate cabin speaker. Pressing the SPKR Key selects and deselects the on-side
speaker unless oxygen masks are in use. While using oxygen masks, the on-side cabin speaker is always on,
pilot audio is always heard on the speaker, and the SPKR Key is disabled on the side in which the oxygen mask
is in use.
All of the radios can be heard over the cabin speakers. 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.
