78Using the GM FunctionUsing the GM FunctionWhat is the GM (Group Monitor) Function?The GM function automatically monitors for any other stations with the GM functionin operation on the same frequency, or stations transmitting in DN mode, withincommunication 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 onthe transceiver screen.Furthermore, the GM function may also be used to exchange data such as messagesand images between group members.Tips• The GM function does not work while in the analog mode. When the GM function is activated, theoperating band automatically switches to DN mode.• When sending an image with the GM function in operation, the operating band automaticallyswitches to FR mode (high-speed data communication mode). Upon completion of the datatransmission, the mode automatically reverts to the original V/D mode (simultaneous voice/datacommunication mode).How to use the GM functionThe GM function enables the display of all stations operating the GM function (up to 24stations).For detailed information about the operation and functions of the GM mode, refer to theseparate GM Function Instruction Manual (download from Yaesu website).
