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. 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.

PASSENGER ADDRESS MODE (PA MODE)
Press and hold the
SPKR
Key for 2 seconds to initiate Passenger Address Mode (if configured). PA Mode is
annunciated by a rapid blinking of the SPKR annunciator. When in PA Mode the crew can use the PTT “Push-
to-Talk” button to deliver announcements over the speaker, to the passenger headsets, or both depending on
configuration.
CLEARANCE RECORDER AND PLAYER
The Audio Panel contains a digital clearance recorder that records up to 2.5 minutes of the selected COM
radio signal. Recorded COM audio is stored in separate memory blocks. Once 2.5 minutes of recording time
have been reached, the recorder begins recording over the stored memory blocks, starting from the oldest block.
