FEATURES
Your RadioShack 200Ch VHF/Air/UHF
Home Scanner lets you in on all the action! This scanner gives you direct access to over 23,000 frequencies,
including those used by police and fire
departments, ambulance and transportation services, government agencies,
and amateur radio services. You can select up to 200 channels to scan and you
can change selections at any time.
Ten Monitor Memories — let you temporarily save ten frequencies located
during a frequency search, so you can
decide if you want to store them permanently.
The scanner’s frequency bands let you
search specific, preset ranges of frequencies quickly and easily.
Band Search — lets you quickly and
easily search preset frequency ranges,
so you can find new and unlisted broadcasts.
Your scanner has all these special features:
Weather Alert — warns you of serious
weather conditions by sounding an
alarm if the weather service transmits a
weather alert tone.
Weather Band Key — scans seven preprogrammed weather channels to keep
you informed about current weather
conditions.
Scanner Control Protocol — lets you
download channel information (frequency, lockout, priority, delay) from your PC
to the scanner.
Ten 20-Channel Storage Banks — let
you store 20 channels in each of ten
banks to group channels so calls are
easier to identify.
Priority Channels — let you set the
scanner to check up to ten channels every 2 seconds so you do not miss important calls.
Direct Search — lets you search for a
transmission starting from a specified
frequency.
Search Skip — lets you select up to 20
frequencies for the scanner to 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 channels you select
from being scanned, so you can skip
over busy channels such as those with a
continuous transmission.

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
• moving your scanner away from the
receiver
• any scrambled or encrypted transmissions
• connecting your scanner to an outlet
that is on a different electrical circuit
from the receiver
According to the Electronic Communications 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
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 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 interference received, including interference

SCANNING LEGALLY
Your scanner covers frequencies used
by many different groups including police and fire departments, ambulance
services, government agencies, private
companies, amateur radio services, military operations, pager services, and
wireline (telephone and telegraph) service providers. It is legal to listen to al4
most every transmission your scanner
can receive. However, there are some
transmissions you should never intentionally listen to. These include:
This scanner has been designed to prevent reception of illegal transmissions.
This is done to comply 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 could allow it to pick
up transmissions that it is not legal to listen to. Doing so could subject you to legal penalties.

Connecting an Outdoor
Antenna
CONNECTING AN
ANTENNA
Instead of the supplied antenna, you can
connect an outdoor base-station antenna (not supplied) to your scanner. Your
local RadioShack store sells a variety of
antennas. Choose the one that best
meets your needs.
Connecting the Supplied
Antenna
You must install an antenna before you
can operate the scanner.
The supplied telescoping antenna helps
your scanner receive strong local signals. To install the antenna, thread it
clockwise into the hole on the scanner’s
top.
When deciding on a base-station antenna and its location, consider these
points:
• The antenna should be as high as
possible on the house.
• 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.
The scanner’s sensitivity depends on
the antenna’s length and various environmental conditions. For the best re6
To connect a base-station antenna, first
remove the supplied antenna from the
scanner. Always use 50-ohm coaxial cable, such as RG-58 or RG-8, to connect
the base-station antenna. For lengths
over 50 feet, use RG-8 low-loss dielectric coaxial cable. If the antenna cable’s
connector does not fit in the ANT jack,
you might also need an antenna plug
20-422.fm Page 7 Friday, January 7, 2000 12:54 PM
adapter. Your local RadioShack store
carries a wide variety of coaxial antenna
cable and connectors.
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.
Cautions:
You must use a Class 2
power source that supplies
10V AC and delivers 300
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.
Cautions:
• Do not run the cable over sharp
edges or moving parts that might
damage it.
• Do not run the cable next to power
cables or other antenna cables.
• Always connect the AC adapter to
the scanner before you connect it to
AC power. When you finish, disconnect the adapter from AC power before you disconnect it from the
scanner.
Insert the AC adapter’s barrel plug into
the AC 10V jack on the back of the scanner, then plug the AC adapter into a
standard AC outlet.
• 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 receptacle unless the blades can be fully
inserted to prevent blade exposure.
7
20-422.fm Page 8 Friday, January 7, 2000 12:54 PM
CONNECTING AN
EXTERNAL SPEAKER
Insert the earphone’s or headphones’
plug into the EXT. SP. jack on the back of
the scanner.
You can connect an optional external
speaker with a 1/8-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, including external speakers.
Insert the speaker’s plug into the EXT.
SP. jack on the back of the scanner.
Note: Plugging in an earphone or headphones disconnects the scanner’s internal speaker.
Listening Safely
To protect your hearing, follow these
guidelines when you use an earphone/
headphones.
Note: Plugging in an external speaker
disconnects the scanner’s internal
speaker.
CONNECTING AN
EARPHONE OR
HEADPHONES
You can connect an optional earphone
or pair of monaural headphones with a 1/8inch (3.5-mm) plug to the scanner. Your
local RadioShack store sells a complete
line of earphones and headphones.

• Set the volume to the lowest setting
before you begin listening. After you
begin listening, adjust the 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 the volume, do not
increase it. Over time, your ears
adapt to the volume level, so a volume level that does not cause discomfort might still damage your
hearing.

UNDERSTANDING BANKS AND BANDS
You can store frequencies into either a
programmable memory location called a
channel, or a temporary memory location called a monitor memory. You can
store a frequency in each of the scanner’s channels (up to 200) and up to 10
monitor memories.
Your scanner also has eight frequency
bands, each covering a specific range of
frequencies you can search.
MONITOR MEMORIES
Monitor memories are temporary storage areas where you can store up to ten
frequencies during a search while you
decide whether to save them into channels. You can manually select and listen
to frequencies stored in monitor memories.
FREQUENCY BANDS
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 10
channel-storage banks (1–9 and 0) of 20
channels each. You can use each
channel-storage bank to group frequencies, 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, 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 police, county sheriffs, or SWAT teams
that use their own frequencies. 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 21 (the first channel in Bank 2).
12
Your scanner has eight frequency
bands, each covering a specific range of
frequencies. You can search these
bands for specific broadcasts by repeatedly pressing BAND until the scanner
displays the band you want.
For example, you can search through all
frequencies between 29.000 and 54.000
MHz for specific broadcasts by repeatedly pressing BAND until 29-54 appears. The scanner then automatically
searches the frequencies in that band.

SPECIAL FEATURES
DELAY
Many agencies use a two-way radio system that might have a pause of several
seconds between a query and a reply.
To avoid missing a reply, you can program a 2-second delay into any of your
scanner’s channels or frequencies.
Then, when the scanner stops on the
channel, DLY appears and the scanner
continues to monitor the channel for 2
seconds after the transmission stops before it resumes scanning or searching.
You can program a 2-second delay in either of the following ways:
• If the scanner is scanning and stops
on an active channel, quickly press
DELAY before it starts to scan again.
• If the desired channel is not
selected, manually select the channel then press DELAY.
If the scanner is searching, press DELAY
during the search. DLY appears on the
display and the scanner automatically
adds a 2-second delay to every transmission it stops on.
To turn off delay on any channel, select
that channel then press DELAY. DLY disappears. To turn off delay for all frequencies during a search, simply press
DELAY.
SKIPPING FREQUENCIES/
CHANNELS
You can scan channels faster by skipping ones that have a continuous transmission, such as a weather channel.
You can lock out up to all 200 channels
while scanning, or skip up to 20 frequencies during a band or direct search.
To skip a channel/frequency while scanning or searching, press S/S-LOCKOUT
when the scanner stops on it.
Notes:
• If you skip more than 20 search frequencies, each new frequency
replaces an earlier one, starting
from the first stored frequency.
• You can manually select skipped
frequencies after you press HOLD to
stop a search. The scanner displays
L/O when you select a skipped frequency. See “Manually Selecting a
Channel” on Page 18).
Removing Skip from
Frequencies
To remove the skip from a frequency
while searching, press HOLD to stop the
search, press ▲ or ▼ to select the
skipped frequency, then repeatedly
press S/S until L/O disappears.
To remove the skip from all frequencies
at once while searching, hold down S/SLOCKOUT until the scanner beeps twice.

you turn on the priority feature. See
“Skipping
Frequencies/Channels”
on Page 19.
• The priority feature must be turned
off to listen to monitor memories.
The scanner automatically designates
the first channel in each bank as that
bank’s priority channel. Follow these
steps to program a different channel as
the priority channel.
To remove the lockout from all channels
while scanning, use the number keys to
select the banks containing the skipped
channels, press MANUAL, then hold
down LOCKOUT until the scanner beeps
twice.
1. Press PROGRAM.
Note: If you turned off the key tone (see
“Turning the Key Tone On or Off” on
Page 21), the scanner does not beep
when you hold down LOCKOUT.
3. Repeat Steps 1 and 2 for each
channel you want to program as a
priority channel.
PRIORITY
The priority feature lets you scan
through programmed channels and still
not miss important or interesting calls on
specific channels. You can program one
stored channel in each bank as a priority
channel (up to 10 total). As the scanner

2. Press ALERT. ALT appears and the
broadcast turns off.
Note: If you are scanning more than one
bank in which a priority channel has
been programmed, the scanner stops
on the lowest-numbered priority channel
first while scanning.
When a severe weather emergency signal is broadcast, the scanner sounds a
loud alarm (regardless of the volume
control setting), and H appears and ALT
flashes. The alarm continues until the
emergency signal stops transmitting.
ORITY.
LISTENING TO THE
WEATHER BAND
The National Oceanic and Atmospheric
Administration (NOAA) uses 7 frequencies to broadcast local forecasts and regional weather information. We have
preprogrammed your scanner with these
frequencies.
Note: For a list of all 7 national weather
frequencies, see “National Weather Frequencies” on Page 22.
To scan the preprogrammed weather
channels, press WX. WX appears, and
the scanner searches the weather channels and stops on an active broadcast. If
a broadcast is weak, press WX again to
continue searching through the weather
channels. Press ▲ or ▼ to switch the
search direction.
Weather Alert
Your scanner’s weather alert feature can
warn you when your local weather station broadcasts a severe weather emergency signal. (See “Testing Alert Tone”).
1. Press WX to find the clearest local
weather broadcasting station.
To manually turn off the siren and exit
the weather alert mode, press ALERT.
Testing Alert Tone
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.
Press ALERT to exit the alert tone mode.
TURNING THE KEY TONE
ON OR OFF
The scanner is preset to sound a tone
each time you press any of its keys.
Follow these steps to turn the scanner’s
key tone on or off.
1. If the scanner is turned on, turn
VOLUME counterclockwise until it
clicks to turn it off.
2. Hold down S/S-LOCKOUT while you
turn on the scanner. no bEEP (if the
key tone is off) or On bEEP (if the
key tone is on) appears for about 3

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 internal 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

TROUBLESHOOTING
If your scanner is not working as it should, these suggestions might help you eliminate the problem. If the scanner still does not operate properly, take it to your local
RadioShack store for assistance.
SYMPTOM
Scanner is on, but will not scan.
SUGGESTION
Be sure SQUELCH is adjusted properly. See “Turning On the Scanner/Setting Volume and Squelch” on Page 14.
Make sure channels are stored in the
channel-storage banks and the scanner is set to scan. See “Scanning
Channels” on Page 17.
Scanner receives stations poorly or not
at all.
Check the antenna (indoor or outdoor).
Signals may be blocked from being received by the scanner due to metal
frames or material in the building.
Change the scanner’s location and try
again.
Be sure SQUELCH is adjusted properly. See “Turning On the Scanner/Setting Volume and Squelch” on Page 14.
• The scanner’s keys do not work.
• The display shows random segments.
Scanner does not work at all.
The scanner might be locked. Reset
the scanner. See “Resetting the Scanner” on Page 14.
Check that the power supply is working.
The scanner might be locked. Reset
the scanner. See “Resetting the Scanner” on Page 14.
Scanner locks on frequencies that have
an unclear transmission.
Be sure SQUELCH is adjusted properly. See “Turning On the Scanner/Setting Volume and Squelch” on Page 14.
Be sure birdie frequencies are not programmed, or listen to birdie frequencies manually. See “Birdie
Frequencies” on Page 22.

CARE AND MAINTENANCE
Your RadioShack 200Ch VHF/Air/UHF Home Scanner is an example of superior design and craftsmanship. The following suggestions will help you care for your scanner 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 malfunction and might invalidate its warranty and void your FCC authorization to operate it. If your scanner is not performing as it should, take it to your local RadioShack
store for assistance.
