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 (see ‘Selecting Channels and Channel Banks’
on page 26).
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 icon (
) will
be displayed in the icon bar 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channel is no longer busy or the signalling is no longer
valid.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.
