range, you can also search your scanner's service
banks. Service banks are preset groups of
frequencies categorized by the type of services
that use those frequencies. For example, many
amateur radio frequencies are located in the Ham
service bank.
When you search and find a desired frequency,
you can store it into a programmable memory
location called a channel. Channels are grouped
into channel-storage banks. Your scanner has 10
channel-storage banks. Each bank contains 100-
channel sets. So the scanner has 1,000 channels.
You can scan the channel storage banks to see if
there is activity on the frequencies stored there.
Note: Search for frequencies to find your
local frequencies, after you have programmed
these frequencies, you can scan channels.

Understanding Banks

Service Banks

The scanner is preprogrammed with all the
frequencies allocated to the Car Band, Marine,
CB Band, FRS/GMRS/MURS, Fire/Police, Aircraft,
and Ham Band services. This helps you quickly find
active frequencies instead of doing a chain search.

Channel Storage Banks

To make it easier to identify and select the
channels you want to listen to, all the channels
are divided into 10 banks of 100 channels. Use
each channel-storage bank to group frequencies,
such as those for the police department, fire
department, ambulance services, or aircraft. For
example, the police department might use four
frequencies in your town while the fire department
uses an additional four. You could program the
four police frequencies starting with Channel 0
