most every transmission your scanner  
can receive. However, there are some  
transmissions you should never inten-  
tionally listen to. These include:  
FCC NOTICE  
Your scanner might cause TV or radio  
interference even when it is operating  
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:  
• telephone conversations (cellular,  
cordless, or other private means of  
telephone signal transmission)  
• pager transmissions  
• any scrambled or encrypted trans-  
missions  
• moving your scanner away from the  
receiver  
• connecting your scanner to an outlet  
that is on a different electrical circuit  
from the receiver  
According to the Electronic Communica-  
tions Privacy Act (ECPA), you are sub-  
ject to fines and possible imprisonment  
for intentionally listening to, using, or di-  
vulging the contents of such a transmis-  
sion unless you have the consent of a  
party to the communication (unless such  
activity is otherwise illegal).  
• contacting your local RadioShack  
store for help  
If you cannot eliminate the interference,  
the FCC requires that you stop using  
your scanner.  
This scanner has been designed to pre-  
vent reception of illegal transmissions.  
This is done to comply with the legal re-  
quirement that scanners be manufac-  
tured so as to not be easily modifiable to  
pick up those transmissions. Do not  
open your scanner’s case to make any  
modifications that could allow it to pick  
up transmissions that it is not legal to lis-  
ten to. Doing so could subject you to le-  
gal penalties.  
This device complies with Part 15 of the  
FCC Rules. Operation is subject to the  
following conditions: (1) This device  
must not cause harmful interference and  
(2) this device must accept any interfer-  
ence received, including interference  
that may cause undesired operation.  
SCANNING LEGALLY  
We encourage responsible, legal scan-  
ner use.  
Your scanner covers frequencies used  
by many different groups including po-  
lice and fire departments, ambulance  
services, government agencies, private  
companies, amateur radio services, mili-  
tary operations, pager services, and  
wireline (telephone and telegraph) ser-  
vice providers. It is legal to listen to al-

REMOVING THE DISPLAY  
PROTECTOR  
Your scanner’s display is protected dur-  
ing shipment by a piece of film. Peel off  
this film before you use the scanner.  
Connecting an Outdoor  
Antenna  
Instead of the supplied antenna, you can  
connect an outdoor base-station anten-  
na (not supplied) to your scanner. Your  
local RadioShack store sells a variety of  
antennas. Choose the one that best  
meets your needs.  
CONNECTING AN  
ANTENNA  
Connecting the Supplied  
Antenna  
When deciding on a base-station anten-  
na and its location, consider these  
points:  
You must install an antenna before you  
can operate the scanner.  
• The antenna should be as high as  
possible on the house.  
The supplied telescoping antenna helps  
your scanner receive strong local sig-  
nals. To install the antenna, thread it  
clockwise into the hole on the scanner’s  
top.  
• The antenna and its cable should be  
as far as possible from sources of  
electrical noise such as appliances  
or other radios.  
• The antenna should be vertical for  
the best performance.  
To connect a base-station antenna, first  
remove the supplied antenna from the  
scanner. Always use 50-ohm coaxial ca-  
ble, such as RG-58 or RG-8, to connect  
the base-station antenna. For lengths  
over 50 feet, use RG-8 low-loss dielec-  
tric coaxial cable. If the antenna cable’s  
connector does not fit in the ANT jack,  
you might also need an antenna plug  
The scanner’s sensitivity depends on  
the antenna’s length and various envi-  
ronmental conditions. For the best re-

adapter. Your local RadioShack store  
carries a wide variety of coaxial antenna  
cable and connectors.  
Cautions:  
You must use a Class 2  
power source that supplies  
10V AC and delivers 300  
!
Once you choose an antenna, follow the  
mounting instructions supplied with the  
antenna. Then route the antenna’s cable  
to the scanner and connect the cable to  
the ANT jack on the back of the scanner.  
mA. Its plug must fit the scanner’s  
AC 10V jack. The supplied adapter  
meets these specifications. Using  
an adapter that does not meet these  
specifications could damage the  
scanner or the adapter.  
• A replacement adapter is available  
by special order through your local  
RadioShack store.  
• Always connect the AC adapter to  
the scanner before you connect it to  
AC power. When you finish, discon-  
nect the adapter from AC power be-  
fore you disconnect it from the  
scanner.  
Cautions:  
• Do not run the cable over sharp  
edges or moving parts that might  
damage it.  
Insert the AC adapter’s barrel plug into  
the AC 10V jack on the back of the scan-  
ner, then plug the AC adapter into a  
standard AC outlet.  
• Do not run the cable next to power  
cables or other antenna cables.  
• Follow all cautions and warnings  
included with your antenna.  
CONNECTING POWER  
Use the supplied 10V, 300-mA AC  
adapter to power the scanner.  
Warning: Do not use the AC adapter’s  
polarized plug with an extension cord re-  
ceptacle unless the blades can be fully  
inserted to prevent blade exposure.  
7
 
Insert the earphone’s or headphones’  
plug into the EXT. SP. jack on the back of  
the scanner.  
CONNECTING AN  
EXTERNAL SPEAKER  
You can connect an optional external  
1/8  
speaker with a -inch (3.5-mm) plug to  
the scanner. Use an 8-ohm external  
speaker that can handle at least 2.5  
watts of power. Your local RadioShack  
store sells scanner accessories, includ-  
ing external speakers.  
Insert the speaker’s plug into the EXT.  
SP. jack on the back of the scanner.  
Note: Plugging in an earphone or head-  
phones disconnects the scanner’s inter-  
nal speaker.  
Listening Safely  
To protect your hearing, follow these  
guidelines when you use an earphone/  
headphones.  
• Set the volume to the lowest setting  
before you begin listening. After you  
begin listening, adjust the volume to  
a comfortable level.  
Note: Plugging in an external speaker  
disconnects the scanner’s internal  
speaker.  
• Do not listen at extremely high vol-  
ume levels. Extended high-volume  
listening can lead to permanent  
hearing loss.  
CONNECTING AN  
EARPHONE OR  
HEADPHONES  
• Once you set the volume, do not  
increase it. Over time, your ears  
adapt to the volume level, so a vol-  
ume level that does not cause dis-  
comfort might still damage your  
hearing.  
You can connect an optional earphone  
1/8  
or pair of monaural headphones with a  
-
inch (3.5-mm) plug to the scanner. Your  
local RadioShack store sells a complete  
line of earphones and headphones.

UNDERSTANDING BANKS AND BANDS  
You can store frequencies into either a  
MONITOR MEMORIES  
programmable memory location called a  
channel, or a temporary memory loca-  
tion called a monitor memory. You can  
store a frequency in each of the scan-  
ner’s channels (up to 200) and up to 10  
monitor memories.  
Monitor memories are temporary stor-  
age areas where you can store up to ten  
frequencies during a search while you  
decide whether to save them into chan-  
nels. You can manually select and listen  
to frequencies stored in monitor memo-  
ries.  
Your scanner also has eight frequency  
bands, each covering a specific range of  
frequencies you can search.  
FREQUENCY BANDS  
CHANNEL-STORAGE  
BANKS  
Your scanner has eight frequency  
bands, each covering a specific range of  
frequencies. You can search these  
bands for specific broadcasts by repeat-  
edly pressing BAND until the scanner  
displays the band you want.  
To make it easier to identify and select  
the frequencies you want to listen to, the  
scanner’s channels are divided into 10  
channel-storage banks (1–9 and 0) of 20  
channels each. You can use each  
channel-storage bank to group frequen-  
cies, such as those used by the police  
department, fire department, ambulance  
services, and amateur radio operators  
(see “Guide to the Action Bands” on  
Page 23).  
For example, you can search through all  
frequencies between 29.000 and 54.000  
MHz for specific broadcasts by repeat-  
29-54  
edly pressing BAND until  
ap-  
pears. The scanner then automatically  
searches the frequencies in that band.  
For example, there might be three or  
four police departments in your area,  
each using several different frequencies.  
Additionally, there might be other law  
enforcement agencies such as state po-  
lice, county sheriffs, or SWAT teams  
that use their own frequencies. You  
could program all law enforcement fre-  
quencies starting with Channel 1 (the  
first channel in Bank 1), then program  
the fire department, paramedic, and oth-  
er public safety frequencies starting with  
Channel 21 (the first channel in Bank 2).

To turn off channel-storage banks, press  
the number key for each of the bank(s)  
so the bank’s number disappears. The  
scanner does not scan any of the stored  
channels within banks you have turned  
off.

Notes:  
• You can manually select any chan-  
nel in a bank, even if the bank is  
turned off.  
• You cannot turn off all ten banks.  
• The scanner skips channels that  
have been locked out (see “Skipping  
Frequencies/Channels” on Page 19.  
MANUALLY SELECTING A  
CHANNEL  
You can continuously monitor a specific  
channel without scanning. This is useful  
if you hear an emergency broadcast on  
a channel and want to hear all the de-  
tails (even though there might be peri-  
ods of silence) or if you want to monitor  
only a specific channel or a locked-out  
channel.  
Follow these steps to manually select a  
channel.  
1. Press MANUAL.  
2. Use the number keys to enter the  
desired channel number, then press  
MANUAL again.  
Notes:  
• If your scanner is scanning and  
stops at the desired channel, simply  
press MANUAL to manually select  
the channel.  
• If you repeatedly press MANUAL,  
the scanner steps through the chan-  
nels.

Testing Alert Tone  
The National Oceanic and Atmospheric  
Administration (NOAA) uses 7 frequen-  
cies to broadcast local forecasts and re-  
gional weather information. We have  
preprogrammed your scanner with these  
frequencies.  
To hear the alert tone, make sure the  
scanner is not set to sound an alert tone,  
press WX, then hold down ALERT. The  
tone sounds and the frequency and  
TESt  
alternately appear.  
Note: For a list of all 7 national weather  
frequencies, see “National Weather Fre-  
quencies” on Page 22.

A GENERAL GUIDE TO SCANNING  
Your scanner’s reception is mainly “line-of-sight.” You usually cannot hear stations  
that are beyond the horizon.  
GUIDE TO FREQUENCIES  
Ham Radio Frequencies  
Ham radio operators often broadcast emergency information when other means of  
communication break down.  
The following chart shows the voice frequencies that you can monitor:  
Wavelength (Meters)  
10-Meter  
6-Meter

Voice (MHz)  
29.000–29.700 MHz  
50.000–54.000 MHz  
144.000–148.000 MHz  
420.000–450.000 MHz  
National Weather Frequencies

162.450  
162.475  
162.500  
162.525  
162.550  
Birdie Frequencies  
Every scanner has birdie frequencies. Birdies are signals created by the scanner’s in-  
ternal circuits. These stray frequencies might interfere with broadcasts on the same  
or similar 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  
SQUELCH clockwise to cut out the birdie.  
This scanner’s known birdie frequencies (in MHz) are 171.250 and 460.0125.  
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 search 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.

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:  
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

CARE AND MAINTENANCE  
Your  
is an example of superior de-  
RadioShack 200Ch VHF/Air/UHF Home Scanner  
sign and craftsmanship. The following suggestions will help you care for your scan-  
ner so you can enjoy it for years.  
Keep the scanner dry. If it gets wet, wipe it dry immediately. Liquids  
might contain minerals that can corrode the electronic circuits.  
Use and store the scanner only in normal temperature environments.  
Temperature extremes can shorten the life of electronic devices, and  
distort or melt plastic parts.  
Keep the scanner away from dust and dirt, which can cause premature  
wear of parts.  
Handle the scanner gently and carefully. Dropping it can damage circuit  
boards and cases and can cause the scanner to work improperly.  
Wipe the scanner with a damp cloth occasionally to keep it looking new.  
Do not use harsh chemicals, cleaning solvents, or strong detergents to  
clean the scanner.  
Modifying or tampering with the scanner’s internal components can cause a mal-  
function and might invalidate its warranty and void your FCC authorization to oper-  
ate it. If your scanner is not performing as it should, take it to your local RadioShack  
store for assistance.
