SCaNNING
Your radio incorporates a scan function that allows a selected
group of channels to be scanned for activity. channels are
scanned at a rate of 20 channels per second. If a signal is
detected on a channel, the scan will pause to allow the signal
to be heard. once the channel has been clear for 5 seconds
the scan will resume.
Scan Groups
Your radio supports two scan groups – Open Scan and
Group 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
switch 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
Group Scan allows you to transmit and receive on your
priority channel, but during periods of inactivity, the
radio will also scan a group of other channels. signals
received on the priority channel will have precedence
over those received on the other channels. similarly,
pressing the PTT while scanning will cause the radio to
revert to the priority channel. once the priority channel
has been clear for 5 seconds the scan will resume.
Example: Scanning channels 1 – 8 with priority
channel 20 in Group Scan
1 - 2 - 3 - 4 - 20 - 5 - 6 - 7 - 8 - 20

this option can be used to quickly jump between channels of
interest or to quickly review which channels are in the scan
memory for editing purposes.
Scanning in Open Scan mode
Briefly press the SCAN key. A high beep will be heard and
the scan symbol will animate. During this time the channel
numbers will scroll rapidly as the channels are scanned.
NOTE: If there are less than 2 channels programmed into the
scan memory when you press SCAN, a low beep will sound
and the command will be ignored.
If a busy channel is located, the scan will pause to allow you
to hear the signal but will continue to animate on the display
to indicate that the scan function is still active. once the
channel has been clear for 5 seconds, the scan will resume.
If you don’t wish to listen to a busy channel you can skip over
it by pressing the Skip button on the microphone or rotating
the Channel knob (or press or

at the next available channel in memory.
