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.

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).

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
2-Meter
70-Centimeter
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
162.400

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.
