The Scanning feature is used to monitor multiple sig-
nals programmed into the transceiver. While scan-
ning, the transceiver will check each channel for the
presence of a signal, and will stop on a channel if a
signal is present.
To activate scanning:
Press the assigned programmable key to activate
scanning.
The scanner will search the channels of each chan-
nel, looking for active ones; it will pause each time
it finds a channel on which someone is speaking.
Press the assigned programmable key again to dis-
able scanning. Operation will revert to the pro-
grammed revert channel.

dio to stay on one of the following channels if you
