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.
Memor
Backup
— keeps the fre­quencies stored in m em ory f or up t o 5 days during a power loss.
Backlit Displa
— makes the display
easy to read in low light conditions.

FCC NOTICE
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.

You can install the supplied window­mount antenna on the inside of your ve­hicle’s windshi eld. Foll ow these steps to install the window -mount antenna .
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.
4. Align the slots around the antenna’s connector with the ta bs on the antenna’s connector and turn it clockwise until it locks int o place.

Warning : Use extreme caution when installing or removing an outdoor an­tenna. If the antenna starts to fall, let it go! It could contact overhead power lines. If the antenna touches a 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 do so yourself.
Caution: Do not run the cable over sharp edges or objects that move.
MOUNTING THE SCANNER IN YOUR VEHICLE
The most common m ounting location for this scanner is under your vehicle’s dashboard. If you use this scanner in a vehicle, mount it securely to avoid damage to the scanner or vehicle, or injury to anyone in the vehicle during sudden starts or stops.
Note: Mobile use of this scanner is unlawful or requires a perm it in some areas. Check the laws in your area.
• Wires and cables will not interf ere with vehicle’s pedals or other moving parts
• The scanner is not directly in front of any heating vents
Follow these steps to mount the scan­ner in your vehicle.
1. Choose a mounting location, then use the mounting bracket as a template to mark the positions for the mounting screw holes.

To protect your hearing, follow these guidelines when you use 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.

Service Search Banks
The FCC (Federal Communications Commission) allocates frequency ranges for the exclusive use of public service agencies such as police de­partments, fire departments, the U.S. Coast Guard, the Federal Aviation Ad­ministration (FAA), and the National Oceanic and Atmospheric Adm inistra­tion (NOAA).
Many of the frequencies used by these agencies are grouped into this scanner’s service search banks, so

CHANNELS
The scanner has 50 empty channels where you can store frequencies you find while scanning the banks or searching through the search bands — 20 in the POLICE bank, 10 in the FIRE/EMG bank, and 20 in the PRI­VATE bank.
• Frequencies you assign to POLICE channels becom e part of the POLICE service search bank. For example, the police depart­ment might use four temporary frequencies while providing secu­rity for a parade. If these frequen-
cies are included in any search band (or even another service search bank), you could store them in Channels 1 POLICE service search bank.
• Frequencies you assign to FIRE/ EMG channels become part of the FIRE/EMG service search bank.
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 FIRE/EMG service search bank.
• The MARINE and AIR service search banks contain no chan­nels.
You can also replace frequencies you stored in these channels with different frequencies, or you can clear stored frequencies from t he channels.

CLEARING FREQUENCIES FROM CHANNELS
You can clear a frequency from a channel by storing an em pty frequen­cy in its place.
Notes:
• You cannot clear or change any of the frequencies in the scanner’s search bands, any of the scan­ner’s preset weather frequencies, or the preset frequencies in the service search banks.

LOCKING OUT CHANNELS AND FREQUENCIES
You can scan banks faster by locking out frequencies or channels that have a continuous transmission or static. However, you cannot lock out any weather frequencies or any frequen­cies within the AIR or MRN service search banks.
To lock out a frequency or channel while scanning, press scanner displays the frequency or channel number.
To remove the lockout, manually se­lect the frequency or channel, then press channel number appears . pears.

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 not scan the bank.
• You can manually select locked out channels.

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.
1. Press

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.
GUIDE TO FREQUENCIES
US Weather Frequencies
162.400 162.425 162.450 162.475
162.500 162.525 162.550
Other Weather Frequencies
161.650 161.775 162.440 163.275
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.
Wavelen
th (meters) Frequencies (MHz)
10-Meter 29.000–29.700
6-Meter 50.000–54.000 2-Meter 144.000–148.000
70-cm 420.000–450.000 33-cm 902.000–928.000
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.
SQ
coun-
25
The birdie frequencies to watch for on this unit are:
31.2000 161.8950 446.3000
41.6000 162.2950 508.7000
52.0000 168.3250 511.4000
114.4000 169.5300 511.4125
155.8700 173.1450
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.

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

CARE AND MAINTENANCE
Your RadioShack PRO -2056 50-Channe l Home/Mobile 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.
Keep the scanner awa y from d ust a nd di rt, whi ch can c au se prem a­ture 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 sc anner’s internal components can caus e a mal­function and might invalidate your scanner’s warranty and void your FCC authoriza­tion to operate it. If your sc anne r is not performing as it shoul d, take it to y our lo cal RadioShack store for assistance.

REPLACING THE FUSES
The fuses in the scanner’s DC power 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).
Warnings:
