What is the GM (Group Monitor) Function?

The GM function automatically monitors for any other stations with the GM function
in operation on the same frequency, or stations transmitting in DN mode, within
communication range. The GM function then displays the acquired information,
including the direction and distance, on the screen for each detected call sign.
In addition to notifying you of the GM group members within your communication range,
the GM function also displays the relative positions of all the members in the group on
the transceiver screen.
Furthermore, the GM function may also be used to exchange data such as messages
and images between group members.
Tips
• The GM function does not work while in the analog mode. When the GM function is activated, the
operating band automatically switches to DN mode.
• When sending an image with the GM function in operation, the operating band automatically
switches to FR mode (high-speed data communication mode). Upon completion of the data
transmission, the mode automatically reverts to the original V/D mode (simultaneous voice/data
communication mode).

How to use the GM function

The GM function enables the display of all stations operating the GM function (up to 24
stations).
