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 system 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.

An active COM frequency displayed in green indicates that the COM transceiver is selected on the Audio 

Panel (COM1 MIC or COM2 MIC Key).  When the PA Key is selected on the Audio Panel, both active COM 
frequencies  appear  in  white  indicating  that  no  COM  radio  is  selected  for  transmitting.    Frequencies  in  the
standby fields are displayed in white.

COM3 is reserved for the optional HF radio. The active HF frequency is not shown on the system.

The active COM frequency displayed in green on the MFD is the same as on PFD1.
