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
All of the radios can be heard over the cabin speaker. 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.
