4.2 COM OPERATION
COM TRANSCEIVER SELECTION AND ACTIVATION
NOTE:
When turning on the avionics 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 displayed on the PFD; 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 (
SPKR
Key is selected and flashing on the Audio Panel).
Frequencies in the standby field are displayed in light blue and white. The standby frequency in the tuning
field is light blue. The other standby frequency is white.
