GROUP SCAN
Group Scan allows you to scan a number of
channels for activity whilst also monitoring your
Priority channel. The receiver will scan the other
channels ONLY WHILE THERE ARE NO SIGNALS
ON THE PRIORITY CHANNEL. If a signal appears
on the Priority channel it will override any signals
being received on any of the other channels. In
addition, if you press the PTT at any time, the
radio will transmit on the Priority channel.
