PRO-71 VHF/UHF/Air
Handheld Scanner
FEATURES
Your new RadioShack PRO-71 VHF/UHF/Air Handheld Scanner lets
you in on all the action! This scanner gives you direct access to 23,000
exciting frequencies that include police department, fire department,
ambulance, aircraft, amateur radio, and transportation services. You
can select up to 100 channels for your scanner to scan and you can
change your selection at any time.
The secret to your scanner’s ability to scan so many frequencies is its
custom-designed microprocessor — a tiny, built-in computer. Your
scanner also has these special features:
Large Liquid-Crystal Display
— lets you easil y see displayed infor -
mation.
Search Skip
— lets you select up to 20 frequencies for the scanner to
skip during a limit or direct search to avoid unwanted frequencies.
Frequency Search
Ten Channel-Storage Banks
— scans through every available frequency.
— let you store 10 channels in each of
ten banks to group frequencies and help you identify calls.
Monitor Memories
— let you temporarily save up to ten channels you
locate during a frequency search.
Two-Second Automatic Scan Delay
— delays scanning for 2 sec-
onds before moving to another channel, so you can hear more replies.
Memory Backup
— keeps the channel frequencies stored in memory
for up to 1 hour during a power loss.
Lock-Out Function
Priority Channel
— keeps channels y ou sel ect fro m bei ng sc anned.
— lets you specify your most important channel and
check it every 2 seconds so you don’t miss important calls.
Weather Band Key
— scans seven preprogrammed weather frequen-
cies so you can hear about current weather conditions.

SCANNING LEGALLY
Your scanner covers frequ encies us ed by many different grou ps includ ing police and fire depa rtments, ambulance se rvices, government agencies, private companies, amateur radio services, military operations,
pager services, 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 (cellular, cordless, or other private means
of telephone signal transmission)
• pager transmissions
• any scrambled or encrypted transmissions
According to the Electronic Communications Privacy Act (ECPA), you
are subject to fi nes an d pos sible im priso nment for inte ntiona lly l isten ing
to, using, or divulging the contents of such a transmission unless you
have the co ns en t o f a p a rty t o th e co mm un i ca tio n ( un les s such activi t y
is otherwise illegal).
4
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 ea sily modi fiable to pick up those
transmissions. Do no t ope n yo ur s can ne r’s c as e to m ak e an y m odi fic ations that could al lo w it to pi ck up tran sm is si ons that it is not lega l to li sten to. Doing so could subject you to legal penalties.
We encourage responsible, legal scanner use.

PREPARATION
POWER SOURCES
You can power your scanner from any of three sources:
• internal batteries
• standard AC power (using an optional AC adapter)
• vehicle batt ery power ( usi ng an option al DC adapter)
INSTALLING BATTERIES
Your scanner requires 4 AA batteries (not supplied) for power. For the
best performance and longest life, we recommend alkaline batteries.
Or, you can use rechargeable nickel-cadmium batteries. Both types of
batteries are available at your local RadioShack store.
Warning:
nickel-cadmium batte ries inside the battery compa rtment. However, you must never use this circuit when you have installed nonrechargeable batteries in th e sc an ner. Be sure to read “Important Info rmation About the External Power Jacks” on Page 9 and “Charging
Nickel-Cadmium Batteries” on Page 12.
Cautions:
• Use only fresh batteries of the required size and recommended

USING VEHICLE BATTERY POWER
You can pow er the scanner from your vehicle’s battery power using an
optional DC adapter, such as Cat. No. 273-1810.
Cautions:
• You must use a DC adapter that supplies 9 volts (regulated) and
delivers at least 300 mA of DC automotive power. Its center tip
must be set to negative and its plug must fit the scanner’s
jack. Both of the recommended adapters meet these specifications. Using an adapter that does not meet these specifications
could damage the scanner or the adapter.
• To protect your vehicle’s electrical system, always plug the adapter
into the scanner before you plug it into your vehicle’s cigarettelighter socket. Always unplug the adapter from the vehicle’s cigarette-lighter socket before you unplug it from the scanner.

CONNECTING THE ANTENNA
Follow these steps to attach the supplied flexible
antenna to the conn ec tor on t he top of your scan ner.
1. Align the slots around the antenna’s connector with the tabs on the jack.
2. Press the antenna down over the jack and
rotate the antenna’s base clockwise until it
locks into place.
Connecting an Optional Antenna
The antenna connecto r on your s canne r makes it ea sy to us e the sc anner with a variety of antennas. Instead of the supplied antenna, you
can attach an external mobile antenna or outdoor base antenna (for
example). Your local RadioShack store sells a variety of antennas.
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 your antenna’s cable does not have a BNC
connector, you will also need a BNC adapter (available at your local
RadioShack store).
Warning:
tion. If the antenna starts to fall, let it go! It could contact overhead
power lines. If the antenna touches the power line, contact with the
antenna, mast, cable, or guy wires can cause electrocution and
death. Call the power company to remove the antenna. Do not attempt to remove it yourself!

Listening Safely
To protect your hearing, follow these guidelines when you use an earphone or 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 highvolume listening can lead to permanent hearing loss.
• Once you set the vo lume, do not increase it. Over time, your ears
adapt to th e volume level, so a volume level that d oes not caus e
discomfort might still damage your hearing.
Traffic Safety
Do not use an earphone or headphones with your scanner when operating a motor vehicle or riding a bicycle in or near traffic. Doing so can
create a traffic hazard and could be illegal in some areas.
If you use an earphone or h ead phones with your scanne r whi le ri din g a
bicycle, be very careful. Do not listen to a continuous broadcast. Even
though some earphones or headphones let you hear some outside
sounds when listening at normal volume levels, they still can present a
traffic hazard.
14
CONNECTING AN EXTENSION SPEAKER
In a noisy area, an optional extension speaker (such as RadioShack
Cat. No. 21-549) or an amplified speaker (such as RadioShack Cat.
No. 21-541), positioned in the right place, might provide more comfortable listening. Plug the speaker cable’s

BANKS AND MEMORIES
Your scanner can store up to 110 frequen cies . You store each fre quency in either a memory called a channel, or a temporary memory called
a monitor memory. This scanner has 100 channels and ten monitor
memories.
CHANNEL-STORAGE BANKS
To make it easier to identify and select the channels you want to listen
to, channels are divided into ten channel-storage banks of 10 channels
each. Use each channel-storage bank to group frequencies, such as
the police department, fire department, ambulance services, or aircraft
band (see “Guide to the Action Bands” on Page31.
For example, the police might use four frequencies, one for each area
of town. You could program the police frequencies starting with Channel 1 (Bank 1) and then program the fire department frequencies starting with Channel 11 (the first channel in Bank 2).
MONITOR MEMORIES
The scanner also has ten monitor memories. Use these memories to
temporarily store frequencies while you decide whether or not to save
them into channels. This is handy for quickly storing an active frequency when you are searching through an entire band.
To store frequencies into a monitor memory, you must first per-

A GENERAL GUIDE TO SCANNING
Reception of the frequencies covered by your scanner is mainly “lineof-sight.” That means you usually cannot hear stations that are beyond
the horizon.
During the summer months, you might be able to hear stations in the
30–50 MHz range located several hundred or even thousands of miles
away. This is because of summer atmospheric conditions. This type of
reception is unpredictable but often very interesting!

Birdie Frequencies
Every scanner has birdie frequencies. Birdies are signals created inside the scanner’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
SQUELCH
clockwise to
cut out the birdie.
The birdie frequency on this unit to watch for is 146.65 MHz.
To find the birdies on your receiver, begin by disconnecting the antenna and moving it awa y from th e re ce ive r. M ak e sure that no other ne arby radio or TV sets are turned on near the receiver. 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.

AVOIDING IMAGE FREQUENCIES
You might discover one of your regular stations on another frequency
that is not listed. It might be what is known as an image frequency. For
example, you might find a service that regularly uses a frequency of
431.875 also on 474.675.
To see if it is an image, do a little math.
Note the new frequency. 474.675
Double the intermediate frequency of 21.4 MHz
(42.8)
and subtract it from the new frequency. –42.8
If the answer is the regular frequency, 431.875
then you have tuned to an image.
Occasionally you might get interference on a weak or distant channel
from a strong broadcast 42.8 MHz below the tuned frequency. This is
rare, and the image signal is usually cleared whenever there is a
broadcast on the actual frequency.
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 by 1,000:
9.62 MHz × 1000 = 9620 kHz
To convert from kHz to MHz, divide by 1,000.
2780 kHz ÷ 1000 = 2.780 MHz
To convert MH z to meters, divide 300 by th e number of megahertz.
300 ÷ 7.1 MHz = 42.25 meters

CARE AND MAINTENANCE
Your RadioShack PRO-71 VHF/UHF/Air Handheld Scanner is an example of superior design and craftsmanship. The following suggestions will help you care for your sca nne r s o y ou can enjoy it f or y ear s.
Keep the sca nner dry. I f it gets we t, 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, damage batteries, 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.
Use only fresh batteries of the required size and recommended type. Batteries can leak chemicals that damage
your scanner’s electronic parts.
Wipe the scanner wi th a damp cloth occas ionally to keep
it looking new. Do no t us e h ars h c he mic al s, 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 you r scanner is not perfor ming as it
should, take it to your local RadioShack store for assistance.
