FINDING AND STORING
ACTIVE FREQUENCIES
Searching the Service Banks
Your scanner contains groups of preset
frequencies called service banks. Each
service bank is associated with a specific
activity (see “Understanding Service Banks/
Banks” on Page 10). You can search for fire/
police, air, ham, and marine transmissions
even if you do not know the specific
frequencies that are used in your area. Then
you can store the frequencies you found into
the scanner's channels or monitor memories.
Note: You can use the scanner's delay
feature while searching the service banks
(see “Using the Delay Function” on
Page 20).
The following steps describe the operation of
the HAM, FD/PD, and AIR service banks. To
listen to the marine bank, see “Listening to
the Marine Bank” on Page 19.
