Pushbutton keys control audio selection. When a key is selected, a triangular

annunciator above the key is illuminated. Annunciator brightness is adjusted

automatically by photocell dimming. Key brightness is adjusted by the radio

dimming bus control. Three Aux inputs are available for additional avionics

or audio devices. During installation, the unit may be configured in various

ways depending on aircraft type and the needs of the pilot.

POWER-UP

The GMA 350H/350Hc 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. For the GMA 350H/350Hc

Traffic unit, the TRFC audio is automatically enabled when the unit is

powered-up, regardless of its state prior to the power cycle.

Stereo headsets are recommended when using the GMA 350H/350Hc.

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.

Transceiver functions may also be accessed via Voice Recognition

NOTE:

commands. Refer to the Voice Recognition section for more information.

Audio from the #1, #2, or #3 COM receiver can be selected independently by

pressing the respective Key(s) (COM1, COM2, or COM3).

Pressing MIC1, MIC2, or MIC3 selects the #1, #2, or #3 transmitter and

simultaneously selects the related COM receiver (COM1, COM2, or COM3)

allowing received audio to be heard. The remaining COM receivers can be added

by pressing their respective keys. During reception of audio from the COM radio

selected for transmission, audio from the other COM radio(s) are muted.
