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.
