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

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.

You can place this scanner on a desk,  
shelf, or table to use it as a base sta-  
tion.  
Your scanner’s front feet fold up and  
down. Adjust them to give you the  
best view of the display.  
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 14 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 13 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-

band, you might hear a frequency  
that you want to store with other fre-  
quencies of the same type, so you  
can scan them all together. You can  
store any frequency into a channel in  
the POLICE or FIRE/EMG service  
search banks or the PRIVATE bank.  
See “Storing Frequencies into Chan-

to these signals. If you want to lis-  
ten to a weak or distant station,  
turn SQ clockwise.  
The scanner scans the channels with-  
in the bank from the lowest to the  
highest channel number. If the scan-  
ner detects a broadcast, it stops on  
the channel. When the broadcast  
ends, the scanner continues to scan  
higher channels in the bank. When the  
scanner finishes scanning all chan-  
nels in the bank, it returns to the low-  
est channel in the bank and starts  
scanning again.  
• If SQ is adjusted so you always  
hear a hissing sound, the scanner  
does not scan properly.

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,

To remove the lockout, manually se-  
lect the frequency or channel, then

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  
162.500  
162.425  
162.525  
162.450  
162.550  
162.475  
163.275  
Other Weather Frequencies  
161.650  
161.775  
162.440  
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.  
Wavelength (meters)  
10-Meter  
6-Meter  
Frequencies (MHz)  
29.000–29.700  
50.000–54.000  
2-Meter  
70-cm  
33-cm  
144.000–148.000  
420.000–450.000  
902.000–928.000  
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,
