COM TRANSCEIVER SELECTION AND ACTIVATION
NOTE:
During PA Mode, the COM MIC Annunciator is extinguished and the COM active frequency color
changes to white, indicating that neither COM transmitter is active.
NOTE:
When turning on the G900X for use, the system remembers the last frequencies used and the active
COM transceiver state prior to shutdown.
The COM Frequency Box is composed of four fields; the two active frequencies are on the left side and the
two standby frequencies are on the right. The COM transceiver is selected for transmitting by pressing the
COM MIC
Keys on the Audio Panel. During reception of audio from the COM radio selected for transmission,
audio from the other COM radio is muted.
An active COM frequency displayed in green indicates that the COM transceiver is selected on the Audio
Panel (
COM1 MIC
or
COM2 MIC
Key). Both active COM frequencies appearing in white indicate that no COM
radio is selected for transmitting (
PA
Key is selected on the Audio Panel).
Frequencies in the standby field are displayed in either white or gray. The standby frequency in the tuning
box is white. The other standby frequency is gray.
