MONO/sTereO heAdseTs
The unit can accommodate up to four (4) headsets (Pilot, Copilot and up
to two (2) passengers). The use of stereo headsets is highly recommended.
If monaural headsets are plugged into stereo jacks, power supply fuses may
be damaged.
When wired correctly, the use of a monaural headset in a stereo jack
shorts the right headset channel to ground. Anyone 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, anyone else listening on a stereo
headset hears audio in the left ear only, unless their headset has a mono/
stereo switch set to mono.
POwer ON/OFF
The GMA 240 may be powered ON and OFF with the avionics master
switch. The unit may also be turned ON and OFF with the Pilot ICS Volume
Knob. Rotate the knob clockwise out of the detent to turn ON. Rotate the
knob counterclockwise into the detent to turn OFF.
During power-up, the unit undergoes a self-test, illuminating all panel
annunciator lights for about two (2) seconds. Once the self-test is complete,
the unit is ready for use with the same keys selected as when the system was
last powered OFF.
TrANsCeIvers
Pressing COM1 MIC or COM2 MIC Key selects the transmitter and receiver
audio for the selected transceiver source. The active COM audio is always
heard on the Pilot headphones. Audio level is controlled by the selected
COM radio volume control.
Either audio source can be selected independently by pressing the COM1
or COM2 receiver keys. When selected this way, they remain active as audio
sources regardless of which transceiver has been selected for microphone
use.
