Using the Digital GM Function

What is the GM function?

The Digital GM (Group Monitor) Function automatically checks if there is another
transceiver operating on the same frequency with the GM function within transmission
range, and displays the direction, distance and other information for each detected
callsign on the LCD. This convenient function not only lets you know if a friend is
within transmission range, but also enables instant confirmation of position information
between group members. Furthermore, by using this function, you can send messages
and images between group members.
Caution
The GM function does not function in the analog mode. Using the % key, switch the communication
mode to AMS (Auto Mode Select Function) or digital mode.
Tip
When transmitting image data while GM function is active, the transmission mode automatically
switches to FR mode (High Speed Data Communication Mode).The transmission mode will
automatically return to the previous V/D mode (Voice/Data Simultaneous Communication Mode).
