to over 23,000 frequencies, including
those used by police and fi re departments, ambulance and transportation
services, government agencies, and
amateur radio services. You can select up to 90 channels to scan and you
can change selections at any time.
The scanner’s frequency bands let
you search specif ic, preset ranges of
frequencies quickly and easily.
Your scanner has all these special
features:

temporarily save three frequencies located during a frequency search, so
you can decide if you want to move
them to permanent channel storage.
Priority Channels
— let you set the
scanner to check up to thr ee channels
every 2 seconds so you do not miss
important calls.
Band Search
— lets you quickly an d
easily search preset frequency ranges, so you can find ne w and unlisted
broadcasts.
Direct Search —
lets you search for a
transmission starti ng from a specified
frequency.
Search Skip
— lets you select up to
20 frequencies fo r the scanner t o skip
during a search, so you can search
more efficiently.
Two-Second Channel Scan/Search
Delay
— lets you set the scanner so it
delays scanning or searching for 2
seconds before moving to another
channel/frequency, so you can hear
more replies.
Lock-Out
— keeps chann els you select from being scanned, so you can
skip over busy channels such as
those with a continuous transmission.
Key Confirmation Tones
— the
scanner sounds a tone when y ou perform an operation correctly and
sounds an error to ne if you make an
error.

FCC NOTICE
Your scanner m ight cause TV or rad io
interference even when it is op erating
properly. To determine whether your
scanner is causing the interference,
turn off your scanner. If the interference goes away, your scanner is
causing it. Try to eliminate the interference by:
• moving your scanner away from
the receiver
• connecting your scanner to an
outlet that is on a different electrical circuit from the receiver
• contacting your local Radio Shack
store for help
If you cannot eliminate the interference, the FCC requires that you s top
using your scanner.
SCANNING LEGALLY
Your scanner covers frequencies
used by many different group s including police and fire departments, ambulance services, government agencie s,
private companies, a mateur rad io ser vices, military operations, pager services, and wireline (telephone and
telegraph) service pro vide rs. It is leg al
to listen to almo st every transmission
your scanner can receive. However,
there are some transmissions you
should never intentionally listen to.
These include:
• telephone conversations (cellular,
cordless, or other private means
of telephone signal transmission)
• pager transmissions
• any scrambled or encrypted transmissions
According to th e Elec tronic Com munications Privacy Act (ECPA), you are
subject to fines and possible imprisonment for intentionally listening to, using, or divulging the contents of such a
transmission unless you have the consent of a par ty to the communication
(unless such activity is otherwise illegal).
This scanner has been designed to
prevent reception of illegal transmissions. This is done to co mply with the
legal requirement that scanners be
manufactured so as to not be easily
modifiable to pick up those transmissions.
Do not open your scanner’s case to
make any modifications that c ould allow it to pick up transmissions that it is
not legal to listen to. Doing so could
subject you to legal penalties.
We encourage responsible, legal
scanner use.

CONNECTING AN
ANTENNA
Connecting the Supplied
Antenna
You must install an antenna before
you can operate the scanner.
The supplied telescoping antenna
helps your scann er receive strong local signals. To install the antenna,
thread it clockwise into the hole on the
scanner’s top.
The scanner’s sensitivity depends on
the antenna’s leng th an d v ariou s e nv ironmental condition s. For the best reception of the transm issions you want
to hear, adjust the antenna’s length.

Connecting an Outdoor
Antenna
Instead of the supplied antenna, you
can connect an outdoor base-station
antenna (not supplied) to your scanner. Your loca l Ra dio Shack store sells
a variety of antennas. Choo se t he on e
that best meets your needs.
When deciding on a base-station antenna and its loc ation, consider these
points:
• The antenna should be as h igh as
possible on the house.
• The antenna and its cable should
be as far as possible from sources
of electrical noise (appliances,
other radios, etc.).
• The antenna shoul d be vertical for
the best performance.

Listening Safely
To protect your hearing, follow these
guidelines when you us e an ear phone
or headphones.
•Set
OFF/VOLUME
to the lowest
setting before you begin liste ning.
After you put on the ear phone or
headphones, adjust
OFF/VOLUME
to a comfortable level.
• Do not listen at extremely high
volume levels. Extended high-volume listening can lead to permanent hearing loss.
• Once you set
OFF/VOLUME
, do

UNDERSTANDING BANKS AND BANDS
You can store frequ encies into either
a permanent memory location called a
channel, or a tempo ra ry me mor y lo ca 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 sp ecific ran ge
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 banks (1–3) of
30 channels each. You ca n use each
channel-storage bank to group frequencies, such as those u sed by the
police department, fire department,
ambulance services, and ama teur radio operators (see “Guide to the Action Bands” on Page 28).
MONITOR MEMORIES
Monitor memories are tem porary storage areas whe re you can store up t o
three frequencies during a search
while you decide whether to save
them into channels . Y ou ca n man ual ly
select and listen to monitor memories.
FREQUENCY BANDS
Your scanner has eight frequency
bands, each co vering a specific range
of frequencies. Y ou can search th ese
bands for specific broadcasts by repeatedly pressing

For example, there mi ght be three or
four police departments i n your area,
each using several different frequencies. Additionally, there might be other
law enforcement agencies such as
state police, county sheriffs, or SWAT
teams that use their own frequenc ies.
You could program all law enforcement frequencies starting with Channel 1 (the first channel in Bank 1), then
program the fire department, paramedic, and other public safety frequencies starting with Channel 31 (the
first channel in Bank 2).

system that might have a pause of
several second s betwee n a quer y and
a reply. To avoi d missing a r eply, you
can program a 2-second delay into
any of your scanne r’s chann els or f requencies. Then, when the scanner
stops on the channel or frequency,
DLY
appears on the display and the
scanner continues to monitor the
channel/frequenc y for 2 seconds afte r
the transmission stops before it resumes scanning or searching.

A GENERAL GUIDE TO SCANNING
Reception of the frequencies covered by your scanner is mainly “line-of-sight.” That
means you usually cannot hear stations that are beyond the horizon.

BIRDIE FREQUENCIES
Every scanner h as birdie frequencie s.
Birdies are signals cr eated inside the
scanner’s receiver. These operating
frequencies might interfere with broadcasts on the s ame frequenci es. If you
program one of these frequencies, you
hear only noise on that frequency. If
the interference is not severe, you
might be able to turn
wise to cut out the birdie.
The birdie frequency to wat ch for with
this scanner is 489.25 MHz.
To find the birdies in your scanner, begin by disconnecting the ant enna and
moving it away from the scanner.
Make sure that no other nea rby radio
or TV sets are turned on near the scanner. Use the search function and
search every freq uency range from its
lowest frequency to the highest. Occasionally, the se arching wil l stop as if it
had found a signal, o ften without any
sound. That is a birdie. Make a list of all
the birdies in your scanner for future
reference.

BAND ALLOCATION
To help decide which frequency ranges to scan, use the following listing of the typical
services that use the frequ encies your scanner recei ves. These frequ encies are subject
to change, and might vary from area to area. For a more complete listing, refer to the
“Police Call Radio Guide inclu ding Fire and Emergency Serv ices,” available at your local
RadioShack store.
Some cities use the 470–512 MHz band for land/mobile service.

AVOIDING IMAGE FREQUENCIES
You might discover one of your regular stations on another frequency that is not listed. It might be wha t is kn own as an i mage frequ ency. For e xample, yo u mig ht fin d
a service that regularly uses a frequency of 431.975 also on 474.775.
To see if it is an image, do a little math.
Note the new frequency. 474.775
Double the intermediate frequency of 21.4 MHz (42.800)
and subtract it from the new frequency.–42.800
If the answer is the regular frequency, 431.975
then you have tuned to an image.
Occasionally, you might get interference on a weak or distant channel from a strong
broadcast 42.8 M Hz be low th e tuned freq uency . This is r are, a nd the imag e signal
is usually cleared whenever there is a broadcast on the actual frequency.
FREQUENCY CONVERSION
The tuning location of a s tation can be e xpressed in frequen cy (kHz or MH z) or in
wavelength (meters). T he following information c an help you make the n ecessary
conversions.
1 MHz (million) = 1,000 kHz (thousand)
To convert MHz to kHz, multiply the number of megahertz by 1,000:
9.62 (MHz ) × 1000 = 9620 kHz
To convert from kHz to MHz, divide the number of kilohertz by 1,000:
2780 (kHz) ÷ 1000 = 2.780 MHz
To convert MHz to meters, divide 300 by the number of megahertz:
300 ÷ 7.1 MHz = 42.25 meters
