GMA 245 Audio Panel
POWER-UP
The GMA 245 performs a self-test during power-up. During the self-test
all Audio Panel annunciator lights illuminate for approximately one second.
Once the self-test is completed, the state of the unit is restored to the state
before the unit was last turned off.
MONO/STEREO HEADSETS
Stereo headsets are recommended when using the GMA 245. 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.
LEFT/RIGHT KNOBS
The Left Inner Knob powers-off the unit, and is used to control pilot ICS
volume. The Left Outer Knob controls pilot music volume. The Right
Inner Knob controls copilot and passenger ICS volume. The Right Outer
Knob controls the copilot and passenger music volume.
