UNDERSTANDING BANKS
Service Banks
The scanner is preprogrammed with all the frequencies
allocated to the weather, ham, marine, aircraft, and po-
lice (fire/emergency) services. This is handy for quickly
finding active frequencies instead of doing a limit
search (see “Service Bank Search” on Page 28).
Channel Storage Banks
To make it easier to identify and select the channels
you want to listen to, channels are divided into 5 banks
of 30 channels each. Use each channel-storage bank
to group frequencies, such as those for the police de-
partment, fire department, ambulance services, or air-
craft (see “Guide to the Action Bands” on Page 58).
For example, the police department might use four fre-
quencies, one for each side of town. You could pro-
gram the police frequencies starting with Channel 1
(the first channel in bank 1), and program the fire de-
partment frequencies starting with Channel 31 (the first
channel in bank 2).
