SCAN GROUPS
Your radio supports three scan groups - Open Scan, Group
Scan and Network Scan. Each scan group has a separate
channel memory allowing you to program your choice of
channels into each group for scanning.
To select Open Scan, Group Scan or Network Scan, press F
then
OS/GS.
‘OPEN’, ‘GROUP’ or NETWK’ will be displayed
at each press.
NOTE:
Network scan is disabled by default and will not
appear in the scan group list unless it has been enabled. See
Network Scan
further below for details on how to enable
and use Network Scan.
Auto Skip
While scanning, if an active channel in your scan group
becomes a nuisance by constantly interrupting the scan,
briefly press or
while the radio is paused on that
channel. The busy channel will be temporarily removed from
the scan group to allow time for the channel to become clear
again and scanning will continue from the next channel in
the sequence. After 30 seconds the skipped channel will be
reinstated in the scan sequence.
If the unwanted active channel continues to interrupt the
scan even after the 30 second skip period has elapsed,
hold
SCAN
while the radio is paused on that channel. The
‘nuisance’ channel will be completely removed from the scan
group for the duration of that scan session. To restore the
channel, simply stop and restart the scan session using the
SCAN
key (or switch the radio Off then On again).
NOTE:
You can skip as many busy channels from the scan
group as you wish, however if you attempt to skip the last
remaining channel, all the previously skipped channels will be
restored to the scan group.
OPEN SCAN
Open Scan allows a group of channels to be scanned in an
ascending sequence. If a signal is found, the scan will pause
on that channel. During this time you can press the
PTT
on
the microphone and talk on the channel. Once the channel
has been clear for 5 seconds the scan will resume.
Example: Scanning Channels 1 – 8 in open scan
1 - 2 - 3 - 4 - 5 - 6 - 7 - 8
Selecting Open Scan
To select Open Scan, repeatedly press
F
followed by
OS/GS
until ‘OPEN’ is displayed.
