After few seconds, scan results are displayed on a histogram.
Each column of the histogram is divided into two parts by a
black line. The lower part indicates the number of
free
channels (RF level < Squelch level - 6dBµV) in the group, while
the upper one the number of channels almost free
(Squelch level < RF level < Squelch level - 6dBµV).
We recommend to choose the group with the highest number
of free channels.
Press SEL to select the desiderate group and choose the
channel as in “
Channel scan ”
After the selection of the desired channel, a screen appears
with the selected frequency, channel and group and it is
possible to Set or Synchronize the receiver with the

button to select the group to scan.
Then it prompts to turn off all transmitters.
So press SEL to start the scan!
After few seconds, scan results are displayed on a chart in

dotted line in the graph indicate the squelch threshold.
Pushing simultaneously UP and DOWN button it’s possible to
zoom the graph to show all the steps of scan
After the selection of the desired frequency, a screen appears
