which is grouped with other channels in a channel-
storage bank. You can then scan the channel-storage
banks to see if there is activity on the frequencies stored
there. Each time the scanner finds an active frequency, it
stays on that channel until the transmission ends.
Channel Storage Banks
To make it easier to identify and select the channels you
want to listen to, your scanner divides the channels into
10 banks (1 to 10) with 20 channels each, for a total of
200 channels. You can use each channel-storage bank
to group frequencies, such as those used by the police
department, fire department, ambulance services, or
aircraft.
For example, you could program the frequencies used
by your local police department starting with Channel
1 (the first channel in bank 1) and program the fire
department frequencies starting with Channel 21 (the
first channel in bank 2).
Service Banks
The scanner is preprogrammed with the frequencies
allocated to marine, fire/police, aircraft, ham radio, and
weather services. This is handy for quickly finding active
frequencies instead of searching through an entire bank
(see “Service Bank Search” on page 22).
