3.3.5 Remote Frequency Selection Control
On units configured for remote Com frequency Recall, pressing the remote
recall switch will load the next preset Com frequency into the unit’s Standby
frequency box. The remote recall switch can be pressed multiple times to scroll
the entire preset frequency list through the Standby frequency box (the list will
“wrap” from the bottom of the list back up to the top, skipping any empty preset
positions).
The standby frequency isn’t activated until a Com flip-flop switch (either
remote- or bezel-mounted) is pressed. Remote Frequency Selection only
functions on units configured for a remote Com Frequency recall switch.
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 MON 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 MON 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.
