Radio Shack 20-423 owner manual Service Banks, Air, Amateur Radio

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.
