3.4 Com Frequency Monitoring
The Frequency Monitoring function allows you to listen to the Standby
frequency in the Com radio, while monitoring the Active frequency for activity.
1. Touch the Monitor key to listen to the standby frequency.
A small “MON” annunciation is displayed to the right of the
Standby frequency. A green bar will show on the Monitor
key. When the Active frequency receives a signal, the unit will
switch automatically to the Active frequency and then switch
back to the standby frequency when activity ceases.
