SCANNING LEGALLY
Your scanner covers frequencies
used by many different groups includ-
ing police and fire departments, ambu-
lance services, government agencies,
private companies, amateur radio ser-
vices, military operations, pager ser-
vices, and wireline (telephone and
telegraph) service providers. It is legal
to listen to almost every transmission
your scanner can receive. However,
there are some transmissions you
should never intentionally listen to.
These include:
• Telephone conversations (either
cellular, cordless, or other private
means of telephone signal trans-
mission)
• Pager transmissions
• Any scrambled or encrypted
transmissions
According to the Electronic Communi-
cations Privacy Act (ECPA), you are
subject to fines and possible imprison-
ment for intentionally listening to, us-
ing, or divulging the contents of such a
transmission unless you have the con-
sent of a party to the communication
(unless such activity is otherwise ille-
gal). We encourage responsible, legal
scanner use.

PREPARATION
Connecting the Window-
Mount Antenna
CONNECTING AN
ANTENNA
You can install the supplied window-
mount antenna on the inside of your ve-
hicle’s windshield. Follow these steps to
install the window-mount antenna.
Connecting the Telescoping
Antenna
The supplied telescoping antenna
helps your scanner receive strong lo-
cal signals. To install this antenna,
hold the antenna so it stands straight
up, then gently push the antenna’s
plug onto the ANT jack on the scan-
ner’s back panel.
Caution: Do not use the window-
mount antenna on a windshield that
has a plastic coating designed to pro-
tect passengers during an accident. If
you use the antenna on this type of
windshield, you might permanently
damage the windshield’s surface.
1. Select a location for the window-
mount antenna. Follow these
mounting guidelines when se-
lecting a location.
• The antenna’s clear wire re-
ceives signals. Mount it verti-
cally against the far right (pas-
senger) side of the windshield.
ANT Jack
The scanner’s sensitivity depends on
the antenna’s length and various envi-
ronmental conditions. Based on the
frequencies of the transmissions you
want to hear, adjust the antenna’s
length.
• Choose a location that does not
block the driver’s view of the
road.
• Some vehicles have Insta-
®
®
Clear or ElectriClear defog-
ging windshields, which have
metal coatings that interfere
with signals. General Motor’s
APV vans have a solar shield
that keeps the vehicle cooler
during the summer, which also
interferes with signals. If you
install a window-mount antenna
in a vehicle with any of these
features, the scanner probably
will not detect weak signals.

2. Clean the selected windshield
area, position the antenna’s clear
wire on the windshield, then press
firmly on both suction cups to
secure it in place.
Connecting an External
Antenna
The ANT jack on the back of the scan-
ner makes it easy to use the scanner
with a variety of antennas. Instead of
one of the supplied antennas, you can
attach a different one, such as an exter-
nal mobile antenna or outdoor base sta-
tion antenna. Your local RadioShack
store sells a variety of antennas.
When deciding on an antenna and its
location, consider the following:
3. Route the antenna’s black cable
down the edge of the windshield,
around the edge of the dash, and
underneath it. Be sure the cable
does not interfere with the vehi-
cle’s pedals or other moving parts.
• The location of the antenna
should be as high as possible.
• The antenna and antenna cable
should be as far as possible from
sources of electrical noise (appli-
ances, other radios, and so on).
• The antenna should be vertical for
the best performance.
Always use 50-ohm coaxial cable,
such as RG-58 or RG-8, to connect
an outdoor antenna. For lengths over
50 feet, use RG-8 low-loss dielectric
coaxial cable. If the coaxial cable’s
connector does not fit in the ANT jack,
you might also need a PL-259-to-BNC
antenna plug adapter, such as Cat.
No. 278-120. Your local RadioShack
store carries a wide variety of coaxial
antenna cable and connectors.
4. Align the slots around the
antenna’s connector with the tabs
on the ANT jack. Then push the
antenna’s connector and turn it
clockwise until it locks into place.
Follow the installation instructions sup-
plied with the antenna, route the anten-
na cable to the scanner, then connect
it to the ANT BNC-type jack on the
back of the scanner.

20-147.fm Page 9 Tuesday, August 3, 1999 3:23 PM
Warning: Use extreme caution when
installing or removing an outdoor an-
tenna. If the antenna starts to fall, let it
go! It could contact overhead power
lines. If the antenna touches a power
line, contact with the antenna, mast,
cable or guy wires can cause electro-
cution and death! Call the power com-
pany to remove the antenna. Do not
attempt to do so yourself.
• Wires and cables will not interfere
with vehicle’s pedals or other
moving parts
• The scanner is not directly in front
of any heating vents
Follow these steps to mount the scan-
ner in your vehicle.
1. Choose a mounting location, then
use the mounting bracket as a
template to mark the positions for
the mounting screw holes.
Caution: Do not run the cable over
sharp edges or objects that move.
MOUNTING THE
SCANNER IN YOUR
VEHICLE
(add corrected illus F6)
The most common mounting location
for this scanner is under your vehicle’s
dashboard. If you use this scanner in
a vehicle, mount it securely to avoid
damage to the scanner or vehicle, or
injury to anyone in the vehicle during
sudden starts or stops.
2. In the marked locations, drill holes
slightly smaller than the supplied
screws. Take care not to drill into
or damage objects behind the
mounting surface.
Note: Mobile use of this scanner is
unlawful or requires a permit in some
areas. Check the laws in your area.
3. Attach the mounting bracket to the
mounting location using the sup-
plied screws and lock washers.
When you choose a mounting loca-
tion, be sure:
• You can easily reach the scanner
(add corrected illus F7)
• All wires and cables will reach
their connection points

20-147.fm Page 10 Tuesday, August 3, 1999 3:23 PM
4. Attach the scanner to the mount-
ing bracket using the supplied
mounting knobs.
3. Insert the power cord’s barrel plug
into the DC 13.8V jack on the back
of the scanner.
To connect the supplied DC cigarette-
lighter power cord, insert its barrel
plug into the DC 13.8V jack on the back
of the scanner, then plug the power
cord into your vehicle’s cigarette-
lighter socket.
(add corrected illus F8)
Connecting Power from Your
Vehicle’s Battery
Depending on if your scanner is per-
manently installed in your vehicle, you
can power it using either the DC pow-
er cord or the DC cigarette-lighter
power cable (both supplied).
(add corrected illus F10)
Follow these steps to connect the sup-
plied DC power cord.
Cautions:
• Unplug the power cord from your
vehicle’s cigarette-lighter socket
when you turn off the ignition. This
prevents vehicle battery drain if
you leave the scanner on when
you turn off the ignition.
(add corrected illus F9. Add
callouts ‘Positive (+)’ and
‘Negative (-)’ to respective
wires)
• Always unplug the power cord
from your vehicle’s cigarette-
lighter socket before you unplug
its barrel plug from the scanner.
1. Connect the power cord’s black
wire to your vehicle battery’s neg-
ative (–) terminal or to a metal part
of the vehicle’s frame that is not
insulated from the frame by a
plastic part.
Note: If the scanner does not operate
when you turn it on, remove the power
cord from your vehicle’s cigarette-
lighter socket and check the socket for
debris. Also, check the fuse in the
power cord you are using (see “Re-
placing the Fuses” on Page 35) and
your vehicle’s fuse block.
2. Connect the power cord’s red wire
(with in-line fuse) to a source of
voltage that turns on and off with
the ignition switch, such as a
spare accessory terminal in your
vehicle’s fuse box.

Warning: Do not use the AC adapt-
er’s polarized plug with an extension
cord, receptacle, or other outlet unless
the blades can be fully inserted to pre-
vent blade exposure.
Using the Supplied AC
Adapter
Cautions:
MEMORY BACKUP
• Use only the supplied AC adapter.
Using a different adapter can
damage your scanner and could
present a safety hazard.
When you first power the scanner,
MEMO LOSS (memory loss) appears
until you program the scanner. The
memory backup circuit begins to func-
tion a few minutes after you supply
power to the scanner. How long the
scanner will maintain channels stored
in memory depends on how long pow-
er has been supplied to the scanner.
• To prevent electric shock, the
plug’s blades are polarized and fit
only one way. If the plug does not
fit easily, turn it over and try again.
Do not force it into the AC outlet.
• When you finish using the AC
adapter, disconnect it from the AC
outlet first. Then disconnect it from
the scanner.
11
If power is continuously supplied to
the scanner for at least 24 hours, the
memory backup circuit maintains the
channels stored in memory for up to 5
days. If power is disconnected and the
memory backup circuit becomes too
weak to save the scanner’s program-
ming, MEMO LOSS appears again

UNDERSTANDING YOUR SCANNER
Once you understand a few simple
terms we use in this manual and famil-
iarize yourself with your scanner’s fea-
tures, you can put the scanner to work
for you. You simply determine the com-
munications you want to hear, then set
the scanner to scan those frequencies.
you can easily scan the frequencies
typically used by a particular agency.
Your scanner has the following ser-
vice search banks.
• POLICE (contains 739 preset fre-
quencies)
A frequency is the tuning location of a
station (expressed in kHz or MHz). To
find active frequencies, you can use
the search function to search search
bands, which are preset ranges of fre-
quencies. When you find a frequency,
you can store it into a permanent
memory location called a channel,
which is grouped with other channels
in your scanner’s service search
banks and PRIVATE bank. You can
then scan these channels. Each time
the scanner finds an active frequency,
it stays there until the transmission
ends.
• FIRE/EMG (contains 197 preset
frequencies)
• MARINE (contains 90 preset fre-
quencies)
• AIR (contains 1,160 preset fre-
quencies)
Your scanner also has 7 preset
weather frequencies.
You can scan through any service
search bank simply by pressing that
bank’s button, or the weather frequen-
cies by pressing WX. For example, if
you want to scan frequencies where
you are likely to hear police calls,
press POLICE.
BANKS
Notes:
Service Search Banks
• You cannot use the SEARCH key
to search for new frequencies in
the service search banks.
The FCC (Federal Communications
Commission) allocates frequency
ranges for the exclusive use of public
service agencies such as police de-
partments, fire departments, the U.S.
Coast Guard, the Federal Aviation Ad-
ministration (FAA), and the National
Oceanic and Atmospheric Administra-
tion (NOAA).
• You cannot change or clear any of
the preset frequencies in the ser-
vice search banks, but you can
store frequencies into channels in
the POLICE and FIRE/EMG ser-
vice search banks (see “Chan-
nels” on Page 14).
Many of the frequencies used by
these agencies are grouped into this
scanner’s service search banks, so

cies are included in any search
band (or even another service
search bank), you could store
them in Channels 1–4 of the
POLICE service search bank.
PRIVATE Bank
Your scanner has one PRIVATE bank.
This bank contains 20 channels. You
can store frequencies from any search
band (see “Search Bands” on
Page 15), service search bank, or any
weather frequency into these chan-
nels, then scan the channels by press-
ing PRIVATE.
• Frequencies you assign to FIRE/
EMG channels become part of the
FIRE/EMG service search bank.
For example, the fire department
might use three frequencies to
communicate with paramedic
units only during disaster drills. If
these frequencies are included in
any search band (or even another
service search bank), you could
store them in Channels 1–3 of the
FIRE/EMG service search bank.
Notes:
• You cannot use the SEARCH key
to search for new frequencies in
the PRIVATE bank.
• You cannot scan the PRIVATE
bank until you have stored fre-
quencies in its channels (see
“Storing Frequencies into Chan-
nels” on Page 21).
• The MARINE and AIR service
search banks contain no chan-
nels.
You can also replace frequencies
you stored in these channels with
different frequencies, or you can
clear stored frequencies from the
channels.
CHANNELS
The scanner has 50 empty channels
where you can store frequencies you
find while scanning the banks or
searching through the search bands
— 20 in the POLICE bank, 10 in the
FIRE/EMG bank, and 20 in the PRI-
VATE bank.
Good references for active frequen-
cies are the RadioShack 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.
• Frequencies you assign to
POLICE channels become part of
the POLICE service search bank.
For example, the police depart-
ment might use four temporary
frequencies while providing secu-
rity for a parade. If these frequen-

You can scan banks faster by locking
out frequencies or channels that have
a continuous transmission or static.
However, you cannot lock out any
weather frequencies or any frequen-
cies within the AIR or MRN service
search banks.
To keep from accidentally changing
the scanner’s programming, you can
lock the scanner’s memory by setting
the MEMOLOCK OFF/ON switch on the
back of the scanner to ON. If you try to
change the scanner’s programming,

Notes:
• The scanner automatically locks
out empty channels.
Many agencies use a two-way radio
system that might have a pause of
several seconds between a query and
a reply.
• You can lock out all frequencies
and channels in a bank. However,
if all frequencies and channels
within a bank are locked out, the
scanner beeps three times when
you press that bank key and does
not scan the bank.
When the scanner tunes to an active
frequency or channel, the scanner
automatically waits for 2 seconds after
the completion of each transmission
on that frequency or channel before it
resumes searching or scanning.
• You can manually select locked
out channels.

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.
GUIDE TO FREQUENCIES
US Weather Frequencies
162.400

Ham Radio Frequencies
Ham radio operators often transmit emergency information when other means of
communication break down. The following chart shows the frequencies the scanner
receives that Ham radio operators normally use.

Birdie Frequencies
Every scanner has birdie frequencies. Birdies are signals created inside the scan-
ner’s receiver. These operating frequencies might interfere with broadcasts on the
same frequencies. 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 SQ coun-
terclockwise to cut out the birdie.

20-147.fm Page 26 Tuesday, August 3, 1999 3:23 PM
The birdie frequencies to watch for on this unit are:
31.2000 161.8950 446.3000
41.6000 162.2950 508.7000
52.0000 168.3250 511.4000
114.4000 169.5300 511.4125
155.8700 173.1450
To find the birdies in your scanner, begin by disconnecting the antenna and moving
it away from the scanner. Make sure that no other nearby radio or TV sets are turned
on near the scanner. Use the search function and scan every frequency range from
its lowest frequency to the highest. Occasionally, the searching will stop as if it had
found a signal, often without any sound. That is a birdie. Make a list of all the birdies
in your scanner for future reference.
GUIDE TO THE ACTION BANDS
United States Broadcast Bands
In the United States, there are several broadcast bands. The standard AM and FM
bands are probably the most well known. There are also four television audio broad-
cast bands — the lower three transmit on the VHF band and the fourth transmits on
the UHF band.

FREQUENCY CONVERSION
The tuning location of a station can be expressed in frequency (kHz or MHz) or in
wavelength (meters). The following information can help you make the necessary
conversions.
1 MHz (million) = 1,000 kHz (thousand)
To convert MHz to kHz, multiply the number of megahertz by 1,000:
30.62 (MHz) ¥ 1000 = 30,620 kHz
To convert from kHz to MHz, divide the number of kilohertz by 1,000:
127,800 (kHz) ÷ 1000 = 127.8 MHz
To convert MHz to meters, divide 300 by the number of megahertz:
300 ÷ 50 MHz = 6 meters

REPLACING THE FUSES
The fuses in the scanner’s DC power
cord and DC cigarette-lighter power
cord help protect your scanner from
power surges and short circuits. If the
fuse in the DC power cord has blown,
replace it with a 1-amp, fast-acting
glass fuse (such as RadioShack Cat.
No. 270-1005). For the fuse in the DC
cigarette-lighter power cord, replace it
with a 2-amp, fast-acting glass fuse
(such as RadioShack Cat. No. 270-
1007).
(add corrected illus F26,

4. To close the fuse holder, push the
fuse holder ends together, then
turn either end clockwise.
Warnings:
• Before you begin, turn off the
scanner and your vehicle’s igni-
tion.
