Your new RadioShack PRO-2056 5 0Channel Home/Mobile Scanner lets
you in on all the action. You can quickly tune to over 2 ,000 preprogrammed
frequencies and search over 20,000
frequencies that include those used by
police and fire departments, ambulance services, aircraft communications, amateur radio services, and
transportation services. The secret to your scanner’s ability to
scan so many frequencies is its
cus to m- designed microprocessor —
a tiny, built-in computer.
Your scanner is preprogrammed for
convenience. By pressing a single button, you can quickly scan those frequencies most widely used by public
service an d other agenc ies. The sca nner even lets you group speci al or i nt eresting freq uencies into their o wn bank.
The scanner is com pact and v ersatile.
You can use it in your home o r mount
it in your vehicle.
Your scanner has these special features:
H
perScan
™
and HyperSearch
™
—
so you can scan up to 100 channels
per second and search up to 100 steps
(frequency intervals) per second, providing faster scan and search speed
than many other scanners.
Service Search
— at the press of a
button, lets you scan preset frequencies in separate police, fire/emergency, marine, and air service search
banks, to make it easy to quickly identify calls. You can also add frequencies to channels in the police and fire/
emergency service search banks.
Band Search
— lets you search for
transmissions within 11 preset frequency ranges, so you can quickly
find interesting frequencies.
PRIVATE Bank
— lets you store up to
20 frequencies that you find while
scanning or searching, so you can
group unusual or special frequencies
together for fast access.
One-Touch Weather Scannin
—
quickly tunes to National Weather Service broadcasts, so you can keep current on important weather information.
Lock-Out Function
— lets you lock
out specif i ed channels, so you can skip
over those channels whi l e s canning.

— keeps the frequencies stored in m em ory f or up t o 5
days during a power loss.

External Speaker Jack — makes it
easy to connect an optional external
speaker or headphones to the scanner.
We recommend you record your scanner’s serial number here. The number
is on the scanner’s back panel.
Two Powe r Options — you can power the scanner from standard AC power with the supplied AC adapter or
your vehicle’s battery with the supplied DC power cord or DC cigarettelighter power cord.
Frequency Guide — this manual lists
currently known frequencies by state
and local area, so you can quickly
tune to local frequencies.
Your PRO-2056 scanner can receive
all of these frequencies:
Your scanner might caus e T V or radi o
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:
• Moving your scanner away from
the TV or radio
• Connecting your scanner to an
outlet that is on a different electr ical circuit from the TV or radio
• Contacting your local RadioShack store for help
In addition, your scanner is preprogrammed with these weather service
frequencies:
• 162.4000 MHz
• 162.4250 MHz
• 162.4500 MHz
• 162.4750 MHz
• 162.5000 MHz
• 162.5250 MHz
• 162.5500 MHz

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 almost every tran smission
your scanner can receive. However,
there are some transmissions you
should never intentionally listen to.
These include:
• Telephone conversations (either
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 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). We encourage responsibl e, legal
scanner use.

CONNECTING AN
ANTENNA
Connecting the Telescoping
Antenna
The supplied telescoping antenna
helps your scanner receive st rong local signals. To install this antenna,
hold the antenna so it stands straight
up, then gently push the antenna’s
plug onto the
ner’s back panel.
The scanner’s sensitivity dep ends on
the antenna’s length and various en vironmental conditions. Based on the
frequencies of the transmissions you
want to hear, adjust the antenna’s
length.

Caution:
mount antenna on a windshield that
has a plastic coating designed to protect passengers during an accident. If
you use the antenna on this type of
windshield, you might permanently
damage the windshield’s surface.
1. Select a location for the window-
Do not use the window-
mount antenna. Follow these
mounting guidelines when selecting a location.
• The antenna’s clear wire receives signals. Mount it vertically against the far right (passenger) side of the windshield.
• Choose a location that does not
block the driver’s view of the
road.
• Some vehicles have Insta-
®
Clear
or ElectriClear® defogging windshields, which have
metal coatings that interfere
with signals. General Motor’s
APV vans have a solar shield
that keeps the vehicle cooler
during the summer, which also
interferes with signals. If you
install a window-mount an ten na
in a vehicle with any of these
features, the scanner probably
will not detect weak signals.

2. Clean the selected windshield
area, position the antenna’s clear
wire on the windshield, then press
firmly on both suction cups to
secure it in place.
3. Route the antenna’s black cable
down the edge of t he windshield,
around the edge of the dash, and
underneath it. Be sure the cable
does not interfere with the vehicle’s pedals or other moving parts.

• 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

For example, the fire department
might use three frequencies to
communicate with paramedic
units only during disaster drills. If
these frequencies are included in
any search band (or even another
service search bank), you could
store them in Channels 1

Many agencies use a two-way radio
system that might have a pause of
several seconds between a q uery and
a reply.
When the scanner tunes to an active
frequency or channel, the scanner
automatically waits for 2 seconds after
the completion of each transmission
on that frequency or chan nel before it
resumes searching or scanning.
• The scanner automatically locks
out empty channels.
• You can lock out all frequencies
and channels in a bank. However,
if all frequencies and channels
within a bank are locked ou t, the
scanner beeps three times when
you press that bank key and does

LISTENING TO
WEATHER
BROADCASTS
The FCC (Federal Communications
Commission) has allocated frequencies for use by the National Oceanic
and Atmospheric Administration
(NOAA). Regulatory agencies in other
countries have also allocated frequencies for use by their weather reporting
authorities.
• 162.4250 MHz
• 162.4500 MHz
• 162.4750 MHz
• 162.5000 MHz
• 162.5250 MHz
• 162.5500 MHz
To hear your local forecast and regional weather information, simply
press WX. Your scanner scans
through the weather frequencies. Your
scanner should stop within a few seconds on your local weather broadcast.
Follow these steps to manually tune to
a specific preprogrammed weather
frequency.

forward or backward through the
frequencies.
Your local weather reporting authority
broadcasts your local forecast and regional weather information on one or
more of these frequencies. If your
scanner is within a weather reporting
authority’s broadcast range, you can
scan these frequencies.

A GENERAL GUIDE TO SCANNING
g
Reception of the frequencies covered by your scanner is mainly “line-of-sight.” That
means you usually cannot hear stations that are beyond the horizon.

Ham Radio Frequen cies
Ham radio operators often transmit emergen cy information when other means of
communication break down. The following chart shows the frequencies the scanner
receives that Ham radio operators normally use.

Birdie Frequencies
Every scanner has birdie frequencies. Birdies are signals created inside the scanner’s receiver. These operating fr equencies might interfere with broadc asts 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
terclockwise to cut out the b irdie.

The birdie frequencies to watch for on this unit are:
31.2000161.8950446.3000
41.6000162.2950508.7000

114.4000169.5300511.4125
155.8700173.1450
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 scan every frequency range from
its lowest frequency to the highest. Occasionally, the s earching 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.
GUIDE TO THE ACTION BANDS
United States Broadcast Bands
In the United States, there are several broadcast bands. The standard AM and FM
bands are probably the most well known. There are also four television audio broadcast ban ds — the lower three transmit on the VHF band and the fourth transmits on
the UHF band.

To help decide which frequency ranges to scan, use the following listing of the typical services that use the frequencies your scanner receives. These frequencies are
subject to change, and might vary from area to area. For a more complete listing,

FREQUENCY CONVERSION
The tuning location of a station can be e xpressed in frequency (kHz or M Hz) 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:
30.62 (MHz) ¥ 1000 = 30, 620 kHz
To convert from kHz to MHz, divide the number of kilohertz by 1,000:
127,800 (kHz) ÷ 1000 = 127.8 MHz
To convert MHz to meters, divide 300 by the number of megahertz:
300 ÷ 50 MHz = 6 meters

cord and DC cigarette-lighter power
cord help protect your scanner from
power surges and short circuits. If the
fuse in the DC power cord has blown,
replace it with a 1-amp, fast-acting
glass fuse (such as RadioShack Cat.
No. 270-1005). For the fuse in the DC
cigarette-lighter power cord, replace it
with a 2-amp, fast-acting glass fuse
(such as RadioShack Cat. No. 270-
1007).
