the radio will resume scanning for further
signals. Exactly how the scanning feature reacts
to a signal will depend on the options
programmed into your radio.
In the following section your working channel
(sometimes called the Priority channel) is
defined as the channel where others would
normally expect to be able to contact you and
is most probably where you would do most of
your communicating.
Scan Groups
There are two possible scan groups available.
These are called
Open Scan (OS)
and
Group
Scan (GS)
. Your radio may be programmed
with either one of these groups or it may have
both groups programmed. In addition, your
radio may also be fitted with a
Dual Watch
feature.
•
Open Scan
allows any of the fitted channels
to be scanned in an ascending sequence
(i.e. from the lowest channel number to the
highest).
•
Group Scan
also allows any of the fitted
channels to be scanned in an ascending
sequence but in addition, it also inserts your
main working channel into the scan
sequence. Your working channel is then
monitored regularly while scanning to ensure
that no calls are missed. Any signal received
on your working channel has priority and will
override any signals received on the other
channels.
•
Dual Watch
allows you to listen to one
selected channel while continuing to monitor
your working channel. As with Group Scan,
your working channel has priority and will
override any signals received on the other
channel.
Selecting a Scan Group:
If you have been given the option of selecting
scan groups, one of the function keys on your
radio will be programmed for
OS/GS
selection.
The current scan group is normally displayed on
the LCD as
OS
for Open Scan or
GS
for Group
Scan.
To change the scan group:
Briefly press the
OS/GS
key. A beep will be
heard and the display will change to indicate
the group you have selected.
Note: To select a scan group, you will first need
to select a channel that does not have an
alphanumeric label.
OS
and
GS
will only appear
on channels not programmed with an
alphanumeric label. If the selected channel has
an alphanumeric label,
OS
or
GS
will not be
displayed because that section of the LCD is
used by the label. However, OS and GS will be
displayed on those channels when the radio is
scanning.
Therefore, to select a scan group on radios
where all channels have alphanumeric labels:
• Press the
Scan
key to activate scanning.
• Select the required scan group with the
OS/
GS
key.
OS
or
GS
will be displayed.
• Press the
Scan
key again to cancel
scanning.
The radio will remain in the selected scan
group.
Selecting Dual Watch
To select the Dual Watch feature:
Press and HOLD the
OS/GS
key until a high
beep is heard. The
SCAN
and
DW
icons will
appear at the bottom of the display along with
the channel number of your working channel.
To cancel the Dual Watch feature:
Press and
HOLD
the
OS/GS
key until a low
beep is heard. The
SCAN
and
DW
icons will
disappear from the display.
Note: If there is no OS/GS key preprogrammed
on your radio, then your scan group will have
been preset for you by your dealer.
