exact frequency of a transmitter is unknown. The following menu is displayed:
1)Range 2)Cont
3)Neighbourhood 4)Exit
Range
This menu option is used to specify the frequencies to scan between. When selected the
following prompt appears:
Enter start frequency
>
Enter the frequency, to the accuracy of 1 kHz, at which you wish the search to start. It is not
necessary to enter the "." before the last three digits, as it will appear automatically. When the
last digit is entered, the display will change to:
Enter end frequency
>
In the same fashion, enter the frequency you wish the search to stop at. When complete, the
following display will appear:
148.999MHz >> Searching
ESC exits
With the dwell time specified using the SET SCAN key, and a step interval specified using the
SET
∆ key on frequency, the receiver will step through the range specified. If a signal is found,
the receiver will find the frequency of maximum signal strength and generate a display like this:
149.419MHz +100
SHIFT=continue ESC=exit
The receiver will remain on the frequency until the signal disappears or either SHIFT or ESC are
pressed. SHIFT will continue the search, ESC will exit the search.
