UNDERSTANDING YOUR SCANNER
Once you understand a few simple terms we use in this manual and familiarize
yourself with your scanner’s features, you can put the scanner to work for you.
You simply find the communications you want to receive, then set the scanner
to scan those frequencies.
A 
frequenc
y is the tuning location of a station (expressed in kHz or MHz). To
find active frequencies, you can use the 
limit 
search function which lets you
search within a specific range of frequencies or the...

and 10 monitor memories.
Channel-Storage Banks
To make it easier to identify and se-
lect the channels you want to listen
to, channels are divided into 10 chan-
nel-storage banks of 20 channels
each. Use each storage bank to
group frequencies, such as the po-
lice department, fire department, am-
bulance services, or aircraft (see
“Guide to the Action Bands” on...

MANUALLY STORING 
FREQUENCIES IN 
CHANNELS
You can manually store up to 200 fre-
quencies into your scanner’s chan-
nels. 
Great references for active frequen-
cies are the RadioShack “Police Call
Guide including Fire and Emergency
Services,” “Official Aeronautical Fre-
quency Directory,” and “Maritime
Frequency Directory.” We update
these directories every year, so be
sure to get a current copy.
If you do not have a reference to fre-
quencies in your area, you can use a
limit or direct search to find...

SEARCHING FOR AND 
TEMPORARILY 
STORING ACTIVE 
FREQUENCIES
You can search for frequencies using
a limit or direct search, then tempo-
rarily store frequencies into monitor
memories.
Limit Search
A limit search lets you search for ac-
tive transmissions within a specified
range of frequencies.
Note: 
You can also use the scan-
ner’s delay feature while using a limit
search (see “Using the 2-Second De-
lay” on Page 27).
Follow these steps to search for ac-
tive frequencies using a limit search.
