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
