Scanning for channel activity
A series of channels can be grouped together so that the
radio can scan through them looking for activity
automatically. Scan groups are selected in the same way
as channels.
Scan group channels can be set up to scan in three
different ways.
They can scan for:
■ Busy channels.
■ Priority channels.
■ The strongest signal (vote).
When the radio is scanning for activity the LED glows amber
and the group name and scanning symbol
will be
displayed, as shown below:
Scanning for a busy channel
In this setup, the radio looks for any activity on the channels
within the scan group. When valid activity is detected the
scanning icon flashes, and the radio will stop on that
channel. Scanning resumes when the channel is no longer
busy or the signalling is no longer valid.
Scanning priority channels
One or two priority channels may also have been
programmed. These channels are scanned more often than
other channels, and are scanned periodically when a non-
priority or lower priority channel is busy.
