Understanding The Scanner; A Look At The Keypad - Radio Shack PRO-89 Owner's Manual

UNDERSTANDING THE SCANNER

Once you understand a few simple terms used in this manual
and familiarize yourself with your scanner's features, you can
put the scanner to work for you. You simply determine the type
of communications you want to receive, then set the scanner to
scan them.
A frequency is the tuning location of a station (expressed in
kHz or MHz). To find active frequencies, you can use the
search function.
You can also search the service-search banks, which are
preset groups of frequencies categorized by type of service.
When you find a frequency, you can store it into a programma-
ble memory location called a channel, which is grouped with
your 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.

A LOOK AT THE KEYPAD

If your scanner's keys seem confusing at first, the following il-
lustration and information should help you understand each
key's function.
Note: Some of the scanner's keys perform more than one
function and are marked with more than one label. The steps in
this Owner's Manual show only the label on the key appropri-
ate to the action being performed.
