FEATURES
Your new RadioShack PRO-72 50-Channel Portable
Scanner gives you direct access to over 32,000 exciting
frequencies, including police and fire depa rtments, ambulance services, and amateur radio services. You can select up to 50 channels to scan, and you can change your
selection at any time.
The secret to your scanner’s ability to scan so many frequencies is it s custom-d esi gned micro pro cessor — a tiny,
built-in computer.
Your scanner has these spec ial features:
Ten Preprogrammed Search Bands
— let you search
for transmissions within preset frequency ranges, so you
can find intere sting frequencies more quickly.
Ten Preprogrammed Weather Frequencies
— keep
you informed about cur rent weather conditions.
HyperScan
and HyperSearch
™
™
—
so you can scan up
to 25 channels per second and search up to 50 steps per
second.
Fifty Channels
— let you store up to 50 of your favorite
frequencies for easy recall and scanning.
Duplicate Frequenc y Check
— automatically warns you
if you try to store a frequency you’ve already stored, to
help you use the scanner’ s mem ory more efficiently.
Monitor Memory
— lets you temporarily save a frequency located during a direct search, so you can move it to
channel storage later.

Channel Lockout — k eeps channels you select from being scanned.
Memory Backup — keeps the channel frequencies
stored in memory for about 1 hour during a power loss.
Two-Second Scan Delay — delays scanning for 2 seconds before moving to another channel, so you can hear
more replies.
Key Lock — lets you lock the keys to help prevent accidentally changing the scanner’s program ming.
Flexible Antenna with BNC Connector — provides excellent rece ption. The BNC conne cto r makes it easy to attach and remove the antenna or a variety of optional
antennas.
Liquid Crystal Display — clearly displays how the scanner is set and makes it easy to change those settings.
Display Backlight — makes the scanner’s display easy
to read in low-light situations.
Three Power Options — you can power the scanner
from int ernal b atter ies (n ot suppl ied – including n onrechargeable batteries, rechargeable batteries, or a rechargeable scanner battery pack) or external AC or DC
power (using optional adapters).
We recommend you record your scanner’s serial number
here. This number is on the scanner’s back panel.

SCANNING LEGALLY
Your scanner covers frequencies used by many different
groups including police and fire departments, ambulance
services, gover nment agencies, private companies, amateur radio services, military operations, pager services,
and wireline (telephone and telegraph) service providers.
It is legal to listen to almost ever y trans missio n your scanner can receive. However, there are some transmissions
you should never intentionally lis ten to. These include:
• Telephone conversations (either cellular, cordless, or
other private mean s of t elephone signal transm ission)
• Pager transmissions
• Any scrambled or encrypted transmissions
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 t he consent of a party to the communication (unless such activi ty
is otherwise illegal). We encourage responsible, legal

PREPARATION
POWER SOURCES
You can power your scanner from any of four sources:
• Internal batteries (not supplied) with the provided
battery holder
• A rechargeable scanner battery pack (not suppl ied)
• Standard AC power (using an optional AC adapter)
• Vehicle battery power (using an optional DC cigarette-
lighter adapter)
Notes:
• Connecting an AC or DC adapter to the scanner dis-
connects any internal batteries, but it does not disconnect a rechargeable battery pack. If you install a
rechargeable battery pack, you can operate the
scanner and recharge the battery pack at the same
time. See “Using Batteries” below and “Charging a
Rechargeable Battery Pack” on Page 14.

Listening Safely
To protect your hearin g, foll ow these gui deli nes when you
use an earphone or headphones:
• Do not listen at extremely high volume levels.
Extended high-volume listening can lead to permanent hearing loss.
• Set the volume to the lowest setting before you begin
listening. After you begin listening, adjust the volume
to a comfortable level.
• 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.
Traffic Safety
Do not use an earphone or headph ones with your sca nner
when operating a motor vehicle or riding a bicycle in or
near traffic. Doing s o can c reate a traff ic haz ard and could
be illegal in some areas.
If you use an earphone or headp hones with your scanner
while riding a bicycle, be very careful. Do not listen to a
continuous broadcast. Even though some earphones/
headphones let you hear some outside sounds when listening at normal volume levels, they still can present a
traffic hazard.

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.
Then, when the scann er stops on the channel,
appears and the scan ner continu es to monitor the channel
for 2 seconds after the transmission stops before it resumes scanning.
You can program a 2-second delay in any of these ways:

Birdie Frequencies
Every scanner has birdi e freq uencies. Birdies are signals created inside the scanner’s receiver. These ope rat ing frequencies might interfere with broadcasts on the
same frequencies. If you program one of these frequencies, you hear only nois e on that frequ ency. If the i nterference is not severe, you might be able to turn
clockwise to cut out the birdie.
The birdie frequencies on this unit to watch for are:
30.735 37.800 38.400
40.000 40.980 41.900
51.200 140.800 149.400

SQUELCH
To find t he birdies i n your s canner, be gin b y d isconne cting
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 s earc h funct ion and sc an eve ry
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 birdi es 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, mul tipl y the number of megaher tz
by 1,000:
30.6 2 (MHz)
x
1000 = 30,620 kHz
To convert from kHz to MHz, divide the number of kilohertz by 1,000:
127,8 00 (k H z ) ÷ 1000 = 127.8 MHz
To convert MHz to meters, divide 300 by the number of
megahertz:
300 ÷ 50 MHz = 6 meters

CARE AND MAINTENANCE
Your RadioShack PRO-72 50-Channel Portable 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, damage batteries, and distort
or melt plastic p arts.
Keep the scanner away from dust and
dirt, which can cause premature wear of
parts.
52
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 type. Batteries can leak chemicals that damage your scanner’s electronic parts .
Wipe the scanner with a dam p cloth occ asionally to keep it looki ng new. Do not use
harsh chemicals, cleaning solvents, or
strong detergents to clean the scanner.
20-566 .fm Page 53 Thurs day, August 5, 1999 8:04 AM
Modifying or tamper ing with the sca nner ’s i nternal components can cause a malfunction and might invalidate your
scanner’s war ranty and vo id your FCC aut horizat ion to operate it. If you r scanner is not perf orming as it sh oul d, take
it to your local RadioShack store for assistance.
