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.

When turning on the G1000 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, (T)182T and (T)206H only].

Frequencies in the standby fields are displayed in white.
