Scanning a group of channels
The scanning feature is used to monitor a pre-
programmed group of channels for activity. When a
busy channel is detected in a group, the radio stops on
(‘captures’) that channel, and you can now hear the call.
Scanning resumes when the channel is no longer busy.
Note:
‘Priority’ channels may be specified when the
radio is programmed. These are channels that you want
the radio to check for activity more often than other
‘non-priority’ channels. Priority channels are scanned
periodically when a non-priority channel is busy.
Understanding the different types of
scanning
The two types of scanning that may be available on your
radio are
standard scanning and background scanning.
Background scan can only be activated using a function
key programmed for background scan. When you
activate background scan, the currently selected
channel automatically becomes a member of the
scan group.
Making a call while scanning
If you want to make a call while your radio is scanning:
1 Lift the microphone off the microphone clip.
2 Press the PTT key to transmit.
If background scan is active, your radio will now call
the currently selected channel.
If standard scan is active and there has been no
recent activity on the channel, then the channel that
is called depends on the way your radio has been
programmed. The possible options are:
!
your radio calls a predetermined channel e.g.
your dispatcher
