3.18.2 F-SCAN

In the operation mode F-SCAN a frequency range which is defined with start frequency and stop
frequency is monitored during scanning. To the current frequency the step frequency is added or
subtracted and the resulting frequency set. For every set frequency the level is measured. On the
occupied channels, that is, channels with a signal bigger than the set squelch threshold, the scanning
stops for a definable time. The effective squelch threshold can be tuned with the squelch potentiometer.
The IF bandwidth should be at least as large as the selected step width.
This menu can be obtained by pressing the F-SCAN softkey in the MAIN menu. The MAIN menu
contains frequency scan menus.

Softkeys
RUN- Scan starts from current frequency or from stop frequency, decreasing frequency
RUN+ Scan starts from current frequency or from start frequency, increasing frequency
Note:
When the current RUN key is in inverse video, this indicates that an F-SCAN is being performed.
If the RUN key is pressed and it is in inverse for only a short time then the complete scan range is
suppressed.
STOP Stops the scan
SUPP The SUPP function suppresses a frequency range. This frequency range is derived
from the current frequency +/- ½ bandwidth. Up to 100 frequency ranges can be stored
and edited in the menu F-SCAN CONFIG SUPP.
CONFIG Goes to the F-SCAN CONFIG configuration menu
Note:
The scan may automatically go from the RUN state to the STOP state when the CYCLE-COUNT is
reached.
