FEATURES

Your RadioShack PRO-2045 200-Channel Weather Alert Home Scan-ner lets you in on all the action! Thisscanner gives you direct access toover 49,500 exciting frequencies usedby police and fire departments, ambu-lance and transportation services, am-ateur radio, as well as aircraftcommunications, Citizen’s Band, andcommercial FM and television broad-casts.

You can select up to 200 channels foryour scanner to scan, and you canchange your selections at any time. Itsrotary tuning control lets you easily se-lect frequencies and channels. Plus,when you turn on the weather alertfunction, the scanner sounds an alarmif the weather service transmits aweather alert tone.

The secret to your scanner’s ability toscan so many frequencies is its cus-tom-designed microprocessor — atiny, built-in computer.

Your scanner has these features:

WX Alert — warns you of seriousweather conditions by sounding analarm if the weather service transmitsa weather alert tone.

Weather Band Auto Scan — scansthe preprogrammed weather frequen-cies so you can stay informed aboutcurrent weather conditions.

Hyperscan — scans programmedchannels at up to 50 channels persecond.

Hypersearch — lets you set the scan-ner to search at up to 300 steps persecond.

Rotar y Tuner — lets you easily tuneand select frequencies or channels.

Auto Sort — lets you scan the chan-nels stored in a bank, in order fromlowest to highest frequency, to in-crease scanning speed.

Auto Store — quickly finds and auto-matically stores active frequenciesinto the selected banks (but does notstore the frequency if it is alreadystored in another channel).

Ten Channel-Stora ge Banks — letyou store 20 channels in each of 10banks to group frequencies so youcan easily identify calls.

Frequenc y Transfer — lets you easi-ly organize your frequencies by trans-ferring them from one channel toanother.

Monitor Memories — let you store upto 10 frequencies you locate during afrequency search.

Limit Search — lets you search fortransmissions within a set range.

Direct Search — lets you search fortransmissions starting from a frequen-cy you specify.

Count Feature — lets you keep trackof how many times your scanner hasstopped on a channel.

Search Skip — lets you select up to50 frequencies for the scanner to skipduring a search, so you can avoid fre-quencies you have already discoveredor that have a continuous transmis-sion.

Two-Second Scan Delay — delaysscanning for 2 seconds before movingto another channel, so you can hearmore replies.

Data Skip — skips data signals (non-modulated signals such as preamblesignals for pagers) during scan, limitsearch, and direct search.

Lock-Out Function — preventschannels you select from beingscanned.

Priority Channels — checks 10 spec-ified channels every 2 seconds so youdo not miss important calls.

Automatic Modulation Mode — se-lects the modulation method — nar-row-band frequency modulation(NFM) or amplitude modulation (AM)— most often used for each band, andlets you manually override the presetmode.

Attenuator — reduces the scanner’ssensitivity to help limit reception tostrong, nearby transmitters.

Memory Backup — keeps storedchannel frequencies in memory for upto 3 days during a power loss.

CTCSS Option — with an optionalCTCSS tone circuit board, you canuse the Continuous Tone CodedSquelch System (CTCSS) to selec-tively listen to some business bandand amateur radio transmissions.

Backlit Display — lets you easily seethe indicators on the scanner’s dis-play, even at night.

We recommend you record your scan-ner’s serial number here. The numberis on the scanner’s back panel.

Your scanner can receive all of thesebands:

FCC NOTICE

Your scanner might cause radio or TVinterference even when it is operatingproperly. To determine if your scanneris causing the interference, turn offyour scanner. If the interference goesaway, your scanner was causing it.Try to eliminate the interference by:

• Moving your scanner away fromthe receiver

• Connecting your scanner to anoutlet that is on a different electri-cal circuit from the receiver

• Contacting a RadioShack store forhelp

If you cannot eliminate the interfer-ence, the FCC requires that you stopusing your scanner.

SCANNING LEGALLY

Your scanner covers frequenciesused by many different groups includ-ing police and fire departments, ambu-lance services, government agencies,private companies, amateur radio ser-vices, military operations, pager ser-vices, and wireline (telephone andtelegraph) service providers. It is legalto listen to almost every transmissionyour scanner can receive. However,there are some transmissions youshould never intentionally listen to.These include:

• Telephone conversations (eithercellular, cordless, or other privatemeans of telephone signal trans-mission)

• Pager transmissions

• Any scrambled or encryptedtransmissions

According to the Electronic Communi-cations Privacy Act (ECPA), you aresubject to fines and possible imprison-ment for intentionally listening to, us-ing, or divulging the contents of such atransmission unless you have the con-sent of a party to the conversation (un-less such activity is otherwise illegal).RadioShack encourages responsible,legal scanner use.

PREPARATION

CONNECTING POWER

You can power your scanner from astandard AC outlet using the suppliedAC adapter or from your vehicle’s bat-tery using an optional DC power cord.

If a power failure occurs or if the pow-er cord is disconnected, the scanner’smemory backup circuit keeps informa-tion in memory for up to 3 days.

Note: The memory backup circuit be-gins to protect memory within a fewminutes after you plug in the scanner.

Using Standard AC Power

Warnin g: Do not use the AC adapterwith an extension cord unless theblades can be fully inserted.

Cautions:

• The supplied AC adapter supplies12 volts and delivers 500 milli-amps. Its center tip is set to posi-tive, and its plug properly fits thescanner’s DC 12V jack. Using anAC adapter that does not meetthese specifications could dam-age the scanner or the adapter.

• Connect the adapter to the scan-ner before you connect it to an ACoutlet. Disconnect the adapterfrom the AC outlet before you dis-connect it from the scanner.

• If you have difficulty inserting theAC adapter’s plug, do not force it.Turn it over and reinsert it.

Follow these steps to use AC power.

1. Insert the supplied AC adapter’sbarrel plug into the scanner’s DC12V jack.

2. Plug the adapter’s power moduleinto a standard AC outlet.

Using Vehicle Battery Power

Use a DC power cord (not supplied),such as RadioShack Cat. No. 270-1533, to power your scanner in yourvehicle.

Cautions:

• The DC power cord you selectmust supply 12 volts and deliverat least 500 mA. Its center tipmust be positive, and its plugmust fit the scanner’s DC 12V jack.The recommended power cordmeets these specifications. Usinga power cord that does not meetthese specifications could dam-age the scanner or power cord.

• Connect the power cord to thescanner before you plug it intoyour vehicle. Disconnect thepower cord from the vehiclebefore you disconnect it from thescanner.

DC 12V

• If you use your scanner in yourvehicle with the engine running,you might hear electrical noisefrom the scanner. This is normal.

Note: Mobile use of this scanner isunlawful or requires a permit in someareas. Check the laws in your area.

Follow these steps to use vehicle bat-tery power.

1. Insert the DC power cord’s barrelplug into the scanner’s DC 12Vjack.

2. Plug the DC power cord’s ciga-rette-lighter plug into your vehi-cle’s cigarette-lighter socket.

CONNECTING AN ANTENNA

You can connect either the suppliedtelescoping antenna or an optional an-tenna to your scanner.

Telescoping Antenna

The supplied telescoping antennahelps your scanner receive strong lo-cal signals. Follow these steps to in-stall the supplied antenna.

1. Hold the antenna so it standsstraight up.

2. Gently push the antenna’s plugonto the ANT jack on the scan-ner’s back panel.

The antenna’s length affects recep-tion. Adjust the antenna’s length asfollows for the best results.

Optional Outdoor Antenna

The supplied antenna is usually goodfor strong, local signals. However, forthe best results in receiving weaker,more distant signals on all bands, youcan attach an optional outdoor anten-na (not supplied), such as a mobile,telescoping, multi-band, or outdoorbase antenna.

Warning: When installing or removingan outdoor antenna, follow all cautionsand warnings included with the anten-na.

DC 12V

29–150 MHz Extend fully

150–174 MHz Extend only 3 seg-ments

216–406 MHz Extend only 2 seg-ments

406–1000 MHz Collapse Fully (only 1 segment extended)

ANT


9

Note: Always use 50-ohm coaxial ca-ble to connect an outdoor antenna toyour scanner. For lengths under 50feet, use RG-58 or RG-8/M coaxial ca-ble. For lengths over 50 feet, use RG-8, low-loss coaxial cable. If the coaxialcable’s connector does not fit the ANTjack, you might also need an adapter.Your local RadioShack store sells acomplete line of outdoor antennas,adapters, BNC connectors, andmounting hardware.

For the best performance, considerthe following when deciding on an out-door antenna and its location:

• The location of the externalantenna should be as high as pos-sible.

• The external antenna andantenna cable should be as faraway as possible from sources ofelectrical noise (appliances, otherradios, and so on).

• The external antenna should bevertical.

Mount the antenna following the in-structions supplied with the antennaand its mounting hardware, then routethe antenna cable to the scanner andconnect it to the ANT jack on the backof the scanner.

RESETTING THE SCANNER

If the scanner’s display locks up ordoes not work properly after you con-nect power or after a power surge, youmight need to reset the scanner.

Caution: This procedure clears all theinformation you have programmedinto the scanner. Use this procedureonly when you are sure your scanneris not working properly.

1. Turn off the scanner.

2. While you press and hold down 2and 9, turn on the scanner.

USING THE FEET

To tilt the display for the best viewingangle and to provide the best traction,pull down on the scanner’s feet sothey lock into place.

10

TESTING ALERT OPERATION

For your scanner’s weather alert func-tion to be effective, you must place thescanner:

• Where it can receive an emer-gency alert broadcast (see “Test-ing Alert Reception” on this page)

• Where you can hear its alert tone(See “Testing the Weather Alert”on Page 11).

Once you determine a location thatmeets these two conditions, leave thescanner there for the best protection.

Testing Alert Reception

The fact that you get clear voice re-ception or that the tone sounds whenyou test the weather alert does notguarantee that an emergency alertbroadcast will trigger your scanner’salert tone. Also, if you are in a fringearea, your scanner might be triggeredby a broadcast in one area, but not betriggered if you place it somewhereelse (even close by).

To test for actual reception, your radiomust receive a test or emergency alertbroadcast. The National Weather Ser-vice (NWS) broadcasts a test alert ev-ery week on Wednesday between 11AM and 12 Noon. To find out the spe-cific test schedule in your area, con-tact your local National Oceanic andAtmospheric Administration (NOAA)or National Weather Service office.

These offices are usually listed in thetelephone book under “US Govern-ment, Department of Commerce.”

To verify that your scanner receivesthe test alert properly, set the scannerto the weather alert standby mode(see “Using the Weather Alert Stand-by Mode” on Page 25) during the timewhen the test alert is broadcast in yourarea.

If the test alert broadcast does not trig-ger your scanner’s tone, you are out ofrange of the broadcast.

Note: If you use your scanner’sweather alert feature when you travel,you cannot guarantee that an emer-gency alert broadcast will trigger thescanner in all areas.

Notes for Weather Alerts:

• To ensure your scanner will soundthe alert tone when it receives anemergency signal, keep theantenna fully extended at alltimes.

• If severe weather threatens, donot wait for an alert tone; turn onyour scanner and monitor the lat-est weather information.


11

Testing the Weather Alert

Follow these steps to test the weatheralert — to hear how it sounds and en-sure that the circuitry is working.

Note: This test does not ensure thatyour scanner will sound an alert whenthe weather service transmits anemergency signal (see “WeatherAlert” on Page 25). Proper operationis affected by the strength of theweather service’s signal.

1. Press WX.

2. When the scanner stops on aweather channel, press ALERT.ALERT appears on the display.

3. Press and hold PRIORITY for morethan 2 seconds until the scannersounds a loud alarm.

To turn off the alarm, press ALERT orWX.

CONNECTING AN EARPHONE

For private listening, plug an earphoneor mono headphones’ 1/8-inch pluginto the jack on the front of the

scanner. This disconnects the internalspeaker.

Note: Your local RadioShack storehas a wide selection of earphones andheadphones.

Listening Safely

To protect your hearing, follow theseguidelines when you use an earphoneor headphone.

• Do not listen at extremely highvolume levels. Extended high-vol-ume listening can lead to perma-nent hearing loss.

• Set the volume to the lowest set-ting before you begin listening.After you begin listening, adjustthe volume to a comfortable level.

• Once you set the volume, do notincrease it. Over time, your earsadapt to the volume level, so avolume level that does not causediscomfort might still damage yourhearing.


12

Traffic Safety

Do not wear an earphone or head-phones while operating a motor vehi-cle. This can create a traffic hazardand can be illegal in some areas.

Even though some earphones andheadphones let you hear some out-side sounds when listening at normalvolume levels, they still can present atraffic hazard.

CONNECTING AN AMPLIFIED EXTENSION SPEAKER

In a noisy area, an amplified extensionspeaker might provide more comfort-able listening. Plug the speaker ca-ble’s 1/8-inch (3.5 mm) mini plug intothe scanner’s jack. This discon-nects the internal speaker.

Note: RadioShack stores sell an am-plified communications extensionspeaker.

INSTALLING AN OPTIONAL CTCSS TONE BOARD

The scanner’s CTCSS (ContinuousTone Control Squelch System) featurelets you choose to listen only to trans-missions that transmit one of 38 stan-dard CTCSS tones. To use CTCSS,you must install an optional CTCSStone board (Cat. No. 20-0031).

Cautions:

• Make sure the scanner is off anddisconnect the power before youinstall a CTCSS tone board.

• Discharge static electricity buildupby touching a metal object beforeyou open the scanner.

1. Use a Phillips screwdriver toremove the two side screws onthe scanner’s top cover and threescrews on the bottom.

Caution: The scanner’s speakeris attached to the top cover andthe circuit board. Use care whenyou remove the top cover to notdamage the speaker or its con-nector.


13

2. Remove the scanner’s top cover.

3. Gently plug the CTCSS board intosockets J9 and J10 on the top ofthe scanner’s circuit board.

4. Replace the scanner’s top cover,then replace the two side screwsand three bottom screws.

Note: For information about usingCTCSS, see “Using CTCSS” onPage 30.

UNDERSTANDING CHANNEL-STORAGE BANKS

You can store up to 210 frequenciesinto your scanner’s memory. Youstore each frequency into either amemory called a channel, or a tempo-rary memory called a monitor. Thisscanner has 200 channel memoriesand 10 monitor memories.

Channel-Storage Banks

To make it easier to identify and selectthe channels you want to listen to,channels are divided into 10 channel-storage banks of 20 channels each.Use each channel-storage bank togroup frequencies, such as the policedepartment, the fire department, am-bulance services, or aircraft (see“Guide to the Action Bands” onPage 34).

For example, the police departmentmight use four frequencies, one foreach side of town. You could programthe police frequencies starting withChannel 1 (the first channel in Bank 1)and then program fire department fre-quencies starting with Channel 21 (thefirst channel in Bank 2).

MONITOR MEMORIES

The scanner also has 10 monitormemories. You can use these memo-ries to temporarily store frequencieswhile you decide whether or not tosave them into channels. This ishandy for quickly storing an active fre-quency when you search through anentire band. See “Searching For andTemporarily Storing Active Frequen-cies” on Page 19.

SPECIAL FEATURES

DELAY

Many agencies use a two-way radiosystem that might have a period of 2or more seconds between a query anda reply. To keep from missing a replyon a specific channel, you can pro-gram a 2-second delay into any chan-nel, or on frequencies during afrequency search. The scanner con-tinues to monitor the frequency for 2seconds after the transmission stopsbefore resuming scanning.

To program a 2-second delay:

• If the scanner is scanning andstops on an active channel,quickly press DELAY before it con-tinues scanning again.

• If the desired channel is notselected, manually select thechannel, then press DELAY.

• If the scanner is searching, pressDELAY while the scanner issearching. DLY appears on thedisplay and the scanner automati-cally adds a 2-second delay toevery transmission it stops on.

To turn off the 2-second delay, pressDELAY while the scanner is monitoringthe channel or while the scanner issearching. DLY disappears from thedisplay.

PRIORITY

The priority feature lets you scanthrough channels and still not miss im-portant or interesting calls on specificchannels. You can program onestored channel in each bank as a pri-ority channel (up to 10 stored chan-nels). As the scanner scans thebanks, it checks the priority channelsevery 2 seconds for activity.

Notes:

• You cannot use the priority anddata skip features at the sametime.

• You cannot use the priority andcount features at the same time.

• You can lock out priority channels.If you lock out all priority channels,the display shows LOC OUt whenyou turn on the priority feature.

• The priority feature must beturned off to listen to monitormemories.

• The scanner checks the lowest-numbered priority channels first. Ifit detects a transmission on a pri-ority channel, it stays on thatchannel and does not check theother priority channels until thetransmission ends.


27

The scanner automatically desig-nates each bank’s first channel as thatbank’s priority channel. Follow thesesteps to program a different channelas the priority channel for a bank.

1. Press PROGRAM.

2. Use the number keys to enter thechannel number you want to pro-gram as the priority channel, thenpress PRIORITY. P appears on thedisplay to the right of the channelnumber.

While you view the count for a chan-nel, you can zero the count by press-ing CLEAR .

To turn off the count display, pressCOUNT until COUNT disappears.

USING CTCSS

CTCSS is frequently used when twodifferent services or groups use thesame frequencies, but are relativelyclose together. Each group sets theirtransmitters to different CTCSS fre-quencies, and sets their receivers toonly let them hear transmissions thatinclude the correct CTCSS frequency.

This helps to avoid radio interferencebetween the groups.

You can use the CTCSS feature tolock out undesired transmissions andmonitor only those which transmit aspecific CTCSS tone.

Note: You must install a CTCSS toneboard before you can use this feature.“Installing an Optional CTCSSTone Board” on Page 12.

A GENERAL GUIDE TO SCANNING

Reception of the frequencies coveredby your scanner is mainly “line-of-sight.” That means you usually cannothear stations that are beyond the hori-zon.

During the summer months, you mightbe able to hear stations in the 30–50MHz range located several hundred oreven thousands of miles away. This isbecause of summer atmospheric con-

ditions. This type of reception is unpre-dictable but often very interesting!

Birdie Frequencies

Birdies are frequencies your scanner uses when it operates. These operating fre-quencies might interfere with broadcasts on the same frequencies. If you tune oneof these frequencies, you hear only noise on that frequency.

If the interference is not severe, you might be able to turn SQUELCH clockwise tocut out the birdie. Here are this scanner’s birdie frequencies that you might want towatch for:

To find the birdies in any receiver, begin by disconnecting the antenna and movingit away from the receiver. Make sure that no other nearby radio or TV sets areturned on near the receiver. Use the search function and search every frequencyrange from its lowest frequency to the highest. Occasionally, the searching will stopas if it had found a signal, often without any sound. That is a birdie. Make a list of allthe birdies in your scanner for future reference.

FREQUENCY CONVERSION

The tuning location of a station can be-expressed in frequency (kHz or MHz) orin wavelength (meters). The followinginformation can help you make the nec-essary conversions.

1 MHz (million)=1,000 kHz (thousand)

To convert MHz to kHz, multiply by1,000.

30.62 MHz x 1000=30620 kHz

To convert from kHz to MHz, divide by1,000.

=127.8 MHz

To convert MHz to meters, divide 300by the number of megahertz.

1.75 meters

TROUBLESHOOTING

If you have problems, here are somesuggestions that might help. If none ofthese suggestions help, take your

scanner to your local RadioShackstore for assistance.

PROBLEM POSSIBLE CAUSE REMEDY

Scanner is totally inop-erative.

No power. Make sure you plugged the scanner into a work-ing AC or DC outlet.

Scanner is on but will not scan.

• SQUELCH is not cor-rectly adjusted.

• A channel has beenmanually selected.

• Adjust SQUELCH clockwise.

• Press SCAN.

While scanning, the scanner locks on fre-quencies that have an unclear transmission.

“Birdies.” Avoid programming fre-quencies listed under “Birdie Frequencies” on Page 33 or only listen to them manually.

Rotary tuner does not work.

Rotary lock is turned on. Press LOCK until FREQ or CHAN appears on the display.

CARE AND MAINTENANCE

Your PRO-2045 200-Channel DirectEntry Programmable Scanner is anexample of superior design and crafts-manship. The following suggestionswill help you care for the PRO-2045 soyou can enjoy it for years.

Keep the scanner dry. Ifit gets wet, wipe it dryimmediately. Liquidscan contain mineralsthat can corrode theelectronic circuits.

Handle the scannergently and carefully.Dropping it can damagecircuit boards and cas-es and can cause thescanner to work im-properly.

Use and store the scan-ner only in normal tem-perature environments.Temperature extremescan shorten the life ofelectronic devices anddistort or melt plasticparts.

Keep the scanner awayfrom dust and dirt,which can cause pre-mature wear of parts.

Wipe the scanner with adamp cloth occasional-ly to keep it lookingnew. Do not use harshchemicals, cleaningsolvents, or strong de-tergents to clean thescanner.

Modifying or tampering with yourscanner’s internal components cancause a malfunction and might invali-date the scanner’s warranty and voidyour FCC authorization to operate it. Ifyour scanner is not operating as itshould, take it to your local Ra-dioShack store for assistance.
