or directly enter a channel number. 
1–9, HOLD/0Each key has a single-digit label, and the 1–3 keys
also have a range of numbers. Use the digits on the
keys to enter the numbers for a channel or a frequen-
cy. Use the range of numbers above the key (
61–90,
for example) to select the channels in a channel-stor-
age bank. See “Channel-Storage Banks” on Page 15.
Also, pressing

UNDERSTANDING BANKS AND BANDS
You can store frequencies into either
a permanent memory location called a
channel, or a temporary memory loca-
tion called a monitor memory. You can
store up to 90 channels and up to 3
monitor memories. 
Your scanner also has eight frequency
bands, each covering a specific range
of frequencies you can search.
CHANNEL-STORAGE 
BANKS
To make it easier to identify and select
the frequencies you want to listen to,
the scanner’s channels are divided
into 3 channel-storage...

This table shows the frequency band ranges displayed by the scanner and the typ-
ical usage, frequency coverage, and step for each.
Notes:
• Your scanner searches at the preset frequency step rate (5 or 12.5 kHz) for
each frequency. You cannot change the frequency step rate.
• The scanner displays the nearest 1 kHz step. For example, if you tune to
406.1125, the scanner displays 
406.112.
• While searching through a frequency band, you might hear a frequency you
want to store. You can store any...

OPERATION
TURNING ON THE 
SCANNER/SETTING 
VOLUME AND SQUELCH
1. Turn OFF/VOLUME and SQUELCH
fully counterclockwise.
2. Turn 
VO L U M E clockwise until you
hear a hissing sound. Set it to the
desired volume level.
3. Turn 
SQUELCH clockwise, then
leave it set to a point just after the
hissing sound stops.
Notes: 
• If the scanner picks up unwanted,
par tial, or very weak transmis-
sions, turn 
SQUELCH clockwise to
decrease the scanner’s sensitivity
to these signals.
• If you want to listen to a weak...

MANUALLY STORING 
FREQUENCIES INTO 
CHANNELS
If you know a frequency you want to
store, you can store it manually into a
channel.
Good references for active frequen-
cies are RadioShack’s “Police Call
Radio Guide Including Fire and Emer-
gency Services,” “Aeronautical Fre-
quency Directory,” and “Maritime
Frequency Directory.” We update
these directories every year, so be
sure to get a current copy. See also
“Guide to the Action Bands” on
Page 28 in this manual.
Note:
 If you do not have a reference...

SEARCHING FOR AND 
TEMPORARILY STORING 
ACTIVE FREQUENCIES
You can search for transmissions us-
ing either a band or direct search, then
temporarily store the frequencies for
those transmissions into monitor
memories.
Notes:
• If you manually tune to a search
skip frequency, the display shows
L/O (see “Skipping Frequencies/
Channels” on Page 23).
• You can use the scanner’s delay
feature while using band or direct
search. See “Delay” on Page 23.

Note: 
You can change the direction of
either an automatic or manual search
by pressing   or   once.
Direct Search
Using direct search, you can enter a
frequency, then search for transmis-
sions above or below that frequency
within all of the frequency bands.
1. Press
 MANUAL.
2. Use the number keys to enter the
frequency where you want to start
the search. Press • to enter the
decimal point.
3. Press   or   to search up or
down from the selected frequency.
