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 optional for use in this aircraft.
