What is the GM Function?
The GM (Group Monitor) function automatically monitors for any other stations with the
GM function in operation on the same frequency, or stations operating 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 (Fast Rate (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).
