Understanding Your Scanner
Service Banks
The scanner is preprogrammed with the
frequencies allocated by fire/police, aircraft,
ham radio, and marine services. In these
service banks, you can search through the
frequencies and store them in channels for
fire/police, aircraft, ham radio, and marine
banks. This is handy for quickly finding active
frequencies instead of searching through an
entire band.
Note: The frequencies in the scanner's
service bank are preset. You cannot change
them.
