Your Radio Shack PRO-2040 100-Channel Programmable Home Scan-ner lets you in on all the action! Thisscanner gives you direct access toover 30,000 exciting frequencies thatinclude police and fire departments,ambulance and transportation ser-vices, and amateur radio. You canselect up to 100 channels to scan,and you can change your selectionsat any time.

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

Your scanner also has these fea-tures:

Hyperscan — scans 50 channelsper second.

Hypersearch — searches throughfrequencies at 300 steps per secondin bands that have 5 kHz steps tohelp you find interesting broadcasts.

Ten 10-Channel Stora ge Banks —let you store 10 channels in each of10 banks to group frequencies soyou can easily identify calls.

Priorit y Channel — checks a speci-fied channel every 2 seconds so youdo not miss important calls.

Data Detection — you can set it todetect data signals (nonmodulatedsignals such as preamble signals forpagers) during a limit or a directsearch so it can automatically contin-ue searching.

Monitor Memories — let you storeup to 10 frequencies you locate dur-ing a frequency search which youcan then transfer into channels.

Search Function — searches fornew and unlisted frequencies using adesignated frequency range (limitsearch) or starting from a specifiedfrequency (direct search).

Selectable Scan/Search Speeds— let you select normal or hyperscan speeds, and normal, high, orhyper search speeds.

Manual or Scan Channel Select —lets you manually specify a singlechannel or set the scanner to auto-matically scan all the stored chan-nels.

Search Skip — lets you select up to50 frequencies for the scanner toskip during a limit or direct search, soyou can avoid unwanted frequen-cies.


3

Two-Second Scan Delay — delaysscanning for 2 seconds before mov-ing to another channel, so you canhear more replies.

Weather Band Key — scans thepreprogrammed weather frequen-cies to keep you informed of the mostcurrent weather conditions.

Memory Backup — keeps the chan-nel frequencies stored in your scan-ner’s memory for up to 3 days duringa power loss.

Squelch Control — lets you adjustthe receiver’s sensitivity low enoughto receive weak signals or highenough to eliminate receiver noisewhen not receiving a signal.

Lock-Out Function — preventschannels you select from beingscanned.

Backlit LCD Display — lets youeasily see the indicators on the scan-ner’s display, even at night.

Audio Output Jack — lets you con-nect an earphone or headphones forprivate listening, or an externalspeaker for listening in a remote ornoisy area.

Optional Antenna Terminals — letyou connect the supplied telescopingantenna to the screw-in terminal, oran external antenna to the BNC con-nector.

Optional Power Sources — let youpower your scanner using the sup-plied AC adapter or an optional DCadapter.

Scanning LegallyScanning is a fun and interesting hobby. You can hear police and fire depart-ments, ambulance services, government agencies, private companies, amateurradio services, aircraft, and military operations. It is legal to listen to almost everytransmission your scanner can receive. However, there are some electronic andwire communications that are illegal to intentionally intercept. These include:

• Telephone conversations (cellular, cordless, or other private means of tele-phone signal transmission)

• Pager transmissions

• Scrambled or encrypted transmissions

According to the Federal Electronic Communications Privacy Act (ECPA), asamended, you could be fined and possibly imprisoned for intentionally listeningto, using, or disclosing the contents of such a transmission unless you have theconsent of a party to the communication (unless such activity is otherwise ille-gal). These laws change from time to time and there might be state or local lawsthat also affect legal scanner usage.

PREPARATION

CONNECTING POWER

Using Standard AC Power

You can power your scanner from astandard AC outlet using the sup-plied AC adapter.

Warnin g: Do not use the AC adapt-er’s polarized plug with an extensioncord receptacle unless the bladescan be fully inserted to prevent bladeexposure.

Cautions:

• The supplied AC adapter sup-plies 12 volts and delivers 500milliamps. Its center tip is set topositive, and its plug properly fitsthe scanner’s DC 12V jack.Using an AC adapter that doesnot meet these specificationscould damage the scanner orthe adapter. The scanner’s dis-play dims if the AC adapter youuse does not provide therequired 12 volts DC.

• Be sure you connect the ACadapter to the scanner beforeyou connect it to a standard ACoutlet. Then disconnect theadapter from the AC outletbefore you disconnect it from thescanner.

• If you have difficulty inserting theAC adapter’s polarized plug, donot force it. Turn it over and rein-sert it.

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

2. Plug the adapter’s power mod-ule into a standard AC outlet.

Memory Backup

If a power failure occurs or if the pow-er cord is disconnected, the scan-ner’s memory backup circuit keepsinformation in memory for up to 3days.

Note: The memory backup circuitbegins to protect the contents inmemory within a few minutes afteryou plug in the scanner.


8

Using Vehicle Battery Power

To power your scanner from your ve-hicle’s battery power, you need a DCpower cord (such as Radio ShackCat. No. 270-1533).

Cautions:

• Your vehicle must have a 12-voltDC, negative-ground electricalsystem.

• The recommended DC powercord supplies 12 volts and deliv-ers at least 500 milliamps. Thecenter tip on the barrel plug isset to positive, and the plugproperly fits the scanner’s DC12V jack. Using a DC power cord(or adapter) that does not meetthese specifications could dam-age the scanner or the cord (oradapter). The scanner’s displaydims if the DC cord (or adapter)you use does not provide therequired 12 volts DC.

• Be sure you connect the DCcord to the scanner before youconnect it to the vehicle’s ciga-rette-lighter plug. Then discon-nect the cord from the vehicle’scigarette-lighter plug before youdisconnect it from the scanner.

Follow these steps to use vehiclebattery power.

1. Insert the barrel plug into thescanner’s DC 12V jack.

2. Plug the other end of theadapter into your vehicle’s ciga-rette-lighter socket.

Note: If the scanner does not oper-ate properly when you use a DC cord(or adapter), unplug the cord (oradapter) from the lighter socket andclean the socket to remove ashesand other debris.

DC 12V Jack

CONNECTING AN ANTENNA

You can connect either the suppliedtelescoping antenna or an optionalantenna.

Telescoping Antenna

To attach the telescoping antenna,simply screw it into the hole on top ofyour scanner.

The antenna’s length controls itssensitivity. Adjust the length of thetelescoping antenna as follows forthe best reception.

29-54 MHz Extend all 3 seg-ments

108-174 MHz Extend only 2 seg-ments

406-956 MHz Collapse Fully (only1 segment extend-ed)

Optional Outdoor Antenna

The supplied antenna is usually ade-quate for strong, local signals. How-ever, for the best results in receivingweaker, more distant signals on allbands, you can attach an optionaloutdoor antenna (not supplied), suchas a mobile, telescoping, multi-band,or outdoor base antenna.

Warning: When installing or remov-ing an outdoor antenna, follow allcautions and warnings included withthe antenna.

Notes:

• This scanner uses a BNCantenna connector. If the coaxialcable’s connector does not fitthe ANT jack, you might alsoneed an adapter. Your localRadio Shack store sells a com-plete line of outdoor antennas,adapters, BNC connectors, andmounting hardware.

• Always use 50-ohm coaxialcable to connect an outdoorantenna. For lengths under 50feet, use RG58 (Cat. No. 278-1314) or RG8/M (Cat. No. 278-1313). For lengths over 50 feet,use RG-8, low-loss coaxial cable(Cat. No. 278-1312).


10

For the best performance, considerthe following when deciding on anoutdoor base antenna and its loca-tion:

• The location of the externalantenna should be as high aspossible.

• The external antenna andantenna cable should be as faraway as possible from sourcesof electrical noise (appliances,other radios, and so on).

• The external antenna should bevertical.

Mount the antenna following the in-structions supplied with the antennaand its mounting hardware, then fol-low these steps to connect an exter-nal antenna.

1. Route the antenna cable to thescanner and connect it to theANT jack on the back of thescanner.

Caution: Do not route the cableover sharp edges or movingobjects.

2. Remove the supplied antennafrom the top of the scanner.

RESETTING THE SCANNER’S DISPLAY

If the scanner’s display locks up afteryou connect a power source, followthese steps to reset it.

1. If the scanner is off, pressPOWER to turn it on.

2. Using a pointed object, such asa straightened paper clip, pressRESET on the back of the scan-ner. The display resets, and thescanner turns off.

3. Press POWER to turn on thescanner again.


11

INITIALIZING THE SCANNER

If the scanner or its display does notwork properly even after resetting it,follow these steps to initialize thescanner.

Caution: Initializing the scannerclears all the channels you stored inmemory. Initialize the scanner onlywhen you are sure it is not workingproperly.

1. If the scanner is off, pressPOWER to turn it on.

2. Press and hold ./CLEAR , thenpress RESET on the back of thescanner using a pointed object,such as a straightened paperclip. The display resets, and thescanner turns off.

3. Press POWER to turn on thescanner.

CONNECTING AN EARPHONE/HEADPHONES/EXTERNAL SPEAKER

The 1/8-inch EXT SP jack on the backof the scanner lets you connect anearphone, headphones, or an exter-nal speaker.

• For private listening, connect anearphone (Cat. No. 33-175).

• For more comfortable private lis-tening, connect monaural head-phones (Cat. No. 20-210).

• For listening from a remote areaor in a noisy area, connect anextension speaker (Cat. No. 21-549).

Note: Connecting any external de-vice to the EXT SP jack automaticallydisconnects the internal speaker.


12

Listening Safely

To protect your hearing, follow theseguidelines when you use an ear-phone or headphones.

• Do not listen at extremely highvolume levels. Extended high-volume listening can lead to per-manent hearing loss.

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

• Once you set the volume, do notincrease it. Over time, your earsadapt to the volume level, so avolume level that does notcause discomfort might stilldamage your hearing.

Traffic Safety

Do not wear an earphone or head-phones while operating a motor vehi-cle or riding a bicycle. This cancreate a traffic hazard and is illegal insome areas.

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


13

17

UNDERSTANDING THE SCANNER’S MEMORY

You can store up to 110 frequenciesinto your scanner’s memory. Youstore each frequency into either amemory called a channel, or a tem-porary memory called a monitor. Thisscanner has 100 channel memoriesand 10 monitor memories.

Channel-Storage Banks

To make it easier to identify and se-lect the channels you want to listento, channels are divided into 10 chan-nel-storage banks of 10 channelseach. Use each channel-storagebank to group frequencies, such asthe police department, fire depart-ment, ambulance services, or aircraft(see “A Guide to the Action Bands”).

For example, the police departmentmight use four frequencies, one foreach side of town. You could pro-gram the police frequencies startingwith Channel 1 (the first channel inBank 1) and program the fire depart-ment starting with Channel 11 (thefirst channel in Bank 2).

Monitor Memories

The scanner has 10 monitor memo-ries. You can use these memories totemporarily store frequencies whileyou decide whether or not to storethem into channels. This is handy forquickly storing an active frequencywhen you search through an entireband. You can manually select thesememories, but you cannot scanthem. See “Searching For and Tem-porarily Storing Active Frequencies.”

When you are in the monitor mode,one of the memory numbers (1-10)appears to the right of the MON indi-cator. The number indicates the cur-rent monitor memory.


18

OPERATION

TURNING ON THE SCANNER/SETTING THE VOLUME AND SQUELCH

1. Turn SQUELCH fully clockwise.

2. Press POWER to turn on yourscanner. The scanner continu-ously scans the unlocked chan-nels.

Note: The first time you turn onthe scanner, the channels mightnot have any frequencies storedin them, but the scanner willcontinuously scan the emptychannels anyway.

3. Press MANUAL to stop the scan-ning. The display shows the cur-rent channel.

4. Turn VOLUME clockwise to setthe scanner’s volume about 1/4of the way between MIN andMAX.

5. Turn SQUELCH counterclock-wise until you hear a hissingnoise.


19

6. Adjust VOLUME to a comfortablelevel.

7. Slowly turn SQUELCH clockwiseuntil the hissing noise stops.

Squelch Tips:

• If the scanner picks upunwanted or weak transmis-sions, slightly turn SQUELCHclockwise to decrease receiversensitivity.

• If the scanner does not pick upany transmissions, slightly turnSQUELCH counterclockwise toincrease receiver sensitivity.

FINDING BIRDIE FREQUENCIES

Birdies are operating frequenciesgenerated and used inside the scan-ner’s receiver. These operating fre-quencies could interfere withbroadcasts on the same frequenciesand make them difficult or impossibleto receive.

These are the most common birdiesto watch for:

31.0500 MHz 134.550 MHz127.2500 MHz 136.050 MHz128.1875 MHz 138.050 MHz128.2500 MHz 140.275 MHz129.6875 MHz 144.900 MHz132.0500 MHz 171.250 MHz132.2625 MHz

If you store one of these frequenciesinto a channel, you might hear onlynoise when the scanner stops on thatfrequency. If the interference is notsevere, you might be able to turnSQUELCH clockwise to cut out thebirdie.

To find your scanner’s specific bird-ies:

1. Disconnect the antenna andmove it away from the scanner.

Note: Make sure that no othernearby radios or TVs are turnedon.

2. Search every frequency bandfrom its lowest frequency to thehighest (see “Searching For andTemporarily Storing Active Fre-quencies”).

If searching stops (as if the scannerhad found a signal) but there is nosound, that frequency might be abirdie.

For future reference, record all thebirdies in your particular scanner.


20

MANUALLY STORING FREQUENCIES IN CHANNELS

You can manually store up to 100 fre-quencies into your scanner’s chan-nels. Radio Shack sells some goodreferences for active frequencies,such as “Police Call Radio Guide In-cluding Fire and Emergency Servic-es,” “Official Maritime FrequencyDirectory” and “Official AeronauticalFrequency Directory.”

Radio Shack updates these directo-ries every year, so be sure to get acurrent copy. If you do not have a ref-erence to frequencies in your area,you can use a limit or direct search tofind a transmission.

Follow these steps to manually storefrequencies.

1. Press MANUAL to stop the scan-ning.

2. Enter the channel number whereyou want to store a frequency.

3. Press PGM. 000.0000MHzPROGRAM, BANK, the banknumber and the selected chan-nel number appear on the dis-play.

4. Enter the frequency you want tostore, including the decimalpoint.

Notes:

• Frequencies are separatedfrom each other in the follow-ing steps:

• When you enter a frequency,the scanner automaticallyrounds it to the nearest validnumber. For example, if youenter the frequency 151.473,your scanner rounds it up to151.475.

Frequencies Steps29.0-108.0 MHz 5 kHz

108-136.975 MHz 12.5 kHz137.0-300.0 MHz 5 kHz

300-3000 MHz 12.5 kHz


21

5. Press ENTER to store the fre-quency into the selected chan-nel.

Note: If you made a mistake inStep 4, Error appears on thedisplay. Repeat Steps 4 and 5.

6. To program the next channel insequence, repeat Steps 3-5.

To program other channels notin sequence, repeat Steps 2-5.

SEARCHING FOR AND TEMPORARILY STORING ACTIVE FREQUENCIES

You can search for frequencies usinga limit or direct search, then eitherskip selected frequencies or tempo-rarily store frequencies into monitormemories.

Limit Search

A limit search lets you search for ac-tive transmissions within a specifiedrange of frequencies.

Note: You can use the scanner’s de-lay feature while using limit search(see “Delay”).

Follow these steps to search for ac-tive frequencies.

1. Press PGM, then LIMIT. Lo and afrequency appear on the display.

2. Using the number keys, enterthe lowest frequency (includingthe decimal point) you want tosearch within the desired fre-quency range, then pressENTER.

3. Press D to search up or — tosearch down starting from thespecified frequency or channel.-d- , SEARCH, and s or tappear, and the next availablemonitor memory flashes on thedisplay.

Note: If you enter an invalid fre-quency, Error appears on thedisplay. To correct this, repeatSteps 2 and 3.

4. When the scanner finds anactive frequency you want tomonitor, you can do one of thefollowing:

• To store the frequency into thecurrent monitor memory,press MON.

• To continue the search, pressD or —.

• To hold the frequency, pressLIMIT. -h- appears on thedisplay.

• Press LIMIT again to exit thehold mode and resume thedirect search.

Notes:

• If you press D or — duringthe hold mode, the frequencychanges in the current stepincrement toward the upper orlower limits.

• If you tune to a search skipfrequency, the display showsLOCKOUT (see “Search SkipMemory”).

Search Skip Memory

You can skip specified frequenciesduring a limit or direct search. Thislets you avoid unwanted frequenciesor ones you have already stored in achannel. You can program up to 50skip frequencies into the scanner’smemory.


24

To skip a frequency, press L/O/SEARCH SKIP when the scannerstops on the frequency during a limitor direct search.

To clear a single frequency from skipmemory so the scanner can stop onit during a limit or direct search, pressLIMIT to hold the search, press D or— to select the skipped frequency,then press L/O/SEARCH SKIP untilLOCKOUT disappears from the dis-play.

To clear all the skip frequencies atonce, while in the search mode,press and hold L/O/SEARCH SKIP un-til the scanner beeps twice.

Notes:

• If you program more than 50skip frequencies, each new fre-quency replaces earlier ones,starting from the first stored fre-quency.

• You can select the skipped fre-quency when the scanner is inthe hold mode. The scanner dis-plays LOCKOUT when youselect a skipped frequency.

LISTENING TO MONITOR MEMORIES

After you temporarily store frequen-cies into the scanner’s monitor mem-ories, you can listen to them bypressing MANUAL , MON, then thenumber for the monitor memory youwant to listen to.

Note: To listen to the monitor memo-ries, the priority channel feature mustbe turned off (see “Designating a Pri-ority Channel”).


25

MOVING A FREQUENCY FROM A MONITOR MEMORY TO A CHANNEL

1. Press MANUAL to stop thescanning.

2. Enter the channel number whereyou want to store the monitorfrequency, then press PGM.PROGRAM appears on the dis-play.

3. Press MON, then enter the moni-tor memory number that has thefrequency you want to store intothe channel. MON and theentered frequency appear, andthe channel number blinks onthe display.

4. Press ENTER. The scannerstores the frequency into theselected channel.

SCANNING THE STORED CHANNELS

To scan the stored channels, pressSCAN. Your scanner scans throughall the stored channels except theones you lock out (see “Locking OutChannels”).

If needed, readjust SQUELCH so youdo not hear the hissing sound be-tween transmissions.


26

Turning Channel-Storage Banks On and Off

You can set your scanner to scanmore efficiently by turning selectedchannel storage banks on and off.When you turn off a bank, the scan-ner does not scan any of the 10channels in the bank.

While scanning, press the numberkey corresponding to the bank youwant to turn on or off. If the memorybank indicator is on, the bank isturned on and the scanner scans allchannels within that bank that are notlocked out. If the indicator is off, thescanner does not scan any of thechannels within that bank.

Notes:

• You can manually select anychannel in a bank, even if thebank is turned off.

• You cannot turn off all banks.There must be at least oneactive bank.

MANUALLY SELECTING A CHANNEL

You can continuously monitor a spe-cific channel without scanning. Thisis useful if you hear an emergencybroadcast on a channel and want tohear all the details (even thoughthere might be periods of silence) orif you want to monitor only a specificchannel or a locked-out channel.

To manually select a channel, pressMANUAL , enter the channel number,then press MANUAL again.

If scanning has stopped at the de-sired channel, simply press MANUALonce.

LISTENING TO THE WEATHER BAND

The FCC (Federal CommunicationsCommission) has allocated 11 chan-nels for use by the National Oceanicand Atmospheric Administration(NOAA).

Your scanner is preprogrammed withthe following frequencies available toNOAA.

162.400 MHz 162.500 MHz

162.425 MHz 162.525 MHz

162.450 MHz 162.550 MHz

162.475 MHz

To hear your local forecast and re-gional weather information, simplypress WX. WX appears on the dis-play.

Your scanner searches through theweather band and stops on an activebroadcast. If a broadcast is weak,press WX again to continue to searchthrough the weather band.

SPECIAL FEATURES

DESIGNATING A PRIORITY CHANNEL

By designating a priority channel,you can scan through the pro-grammed channels and still not missan important or interesting call on aspecific channel.

Note: You can select only one chan-nel as the priority channel.

To program a stored channel as thepriority channel, press PGM, the de-sired stored channel number, thenPRI/HYPER SEARCH. P appears onthe display.

To turn on the priority feature, pressPRI/HYPER SEARCH during scan-ning. PRIORITY appears on thedisplay. The scanner now checks thepriority channel every 2 seconds,and stays on the channel if there isactivity. P appears on the displaywhenever the scanner is set to thepriority channel.

To turn off the priority feature, pressPRI/HYPER SEARCH until PRIORI-TY disappears from the display.

USING THE 2-SECOND DELAY

Many agencies use a two-way radiosystem that might have a period ofseveral seconds between a queryand a reply. To avoid missing a reply,you can program a 2-second delayinto any channel. When the scannerstops on an active channel with aprogrammed delay, it continues tomonitor the channel for 2 seconds af-ter the activity stops before resumingscanning.

To program a 2-second delay into aspecific channel, manually select thedesired channel then press DLY. DE-LAY appears on the display.

To program a 2-second delay whenthe scanner stops on an active chan-nel during scanning, quickly pressDLY while the channel is still active.DELAY appears on the display.

To turn off the programmed delay onany active channel, press DLY whilethe channel is still active. DELAY dis-appears from the display.


29

LOCKING OUT CHANNELS

You can set your scanner to scanmore efficiently by locking out chan-nels you do not want to monitor. Thisis handy for locking out channelswhere you stored a frequency with acontinuous transmission, such as aweather channel.

To lock out a channel, press MANU-AL , enter the desired channel num-ber, press MAN or PGM to select thechannel, then press L/O/SEARCHSKIP so LOCKOUT appears on thedisplay.

Notes:

• You can still manually selectlocked out channels.

• You cannot lock out all channels.There must be at least oneactive channel in each bank.

To unlock a channel, manually selectthe channel, then press L/O/SEARCHSKIP so LOCKOUT disappears fromthe display.

To unlock all channels, while thescanner is scanning, select thebanks containing the locked chan-nels you want to unlock, press MAN-UAL , then press and hold L/O/SEARCH SKIP until the scannerbeeps twice.

CHANGING SCANNING AND SEARCH SPEEDS

The PRO-2040 has two scan andthree search speeds.

To change the scanning speed, dur-ing scanning, press SPEED to switchbetween normal and hyper scanspeeds. SCAN flashes on the displayduring hyper scan speed.

Notes:

• You can also change the searchspeeds when you listen to theweather band.

• s or t flashes on the display dur-ing high speed search.

To change the search speed, duringa limit or direct search, press SPEEDto switch between the normal andhigh speed search speeds. s or tflashes on the display during highspeed search.

To select the hyper search speed,during a limit or direct search, pressPRI/HYPER SEARCH. SEARCH flash-es on the display during hyper searchspeed.

Note: You can use hyper searchspeed only in 5 kHz-step bands.

DETECTING DATA SIGNALS

You can set the scanner to detectdata signals (nonmodulated signalssuch as preamble signals for pagers)during a limit or direct search.

Note: You cannot detect data signalsin the air band (AM mode).

To detect data signals, press DATAso DATA appears on the display. Ifthe scanner momentarily pauses ona transmission and detects a datasignal, it resumes searching in 2 or 3seconds.

To stop detecting data signals, pressDATA so DATA disappears from thedisplay.

A GENERAL GUIDE TO SCANNING

Reception of the frequencies cov-ered by your scanner is mainly “line-of-sight.” That means you usuallycannot hear stations that are beyondthe horizon. During the summermonths, you might be able to hearstations in the 30-50 MHz range lo-cated several hundred or even thou-sands of miles away. This is becauseof summer atmospheric conditions.This type of reception is unpredict-able but often very interesting!

FREQUENCY CONVERSION

The tuning location of a station can be expressed in frequency (kHz or MHz) orin wavelength (meters). The following information can help you make the neces-sary 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 MHz to meters, divide 300 by the number of megahertz.

300 ÷ 7.1 MHz = 42.25 meters

TROUBLESHOOTING

Your Radio Shack PRO-2040 100-Channel Programmable Home Scannershould require very little maintenance. If you have problems, refer to this chartfor possible solutions. If you cannot solve the problem, contact your local RadioShack store for assistance.

Problem Probable Cause SolutionScanner is totally inoperative. The AC or DC adapter

is not properly con-nected.

Be sure the adapter is fully inserted into the DC 12V jack and into a working AC or DC power source receptacle

The display dims. The AC or DC adapter does not provide the required 12 volts DC.

Be sure the adapter is set to provide no less than 12 volts DC.

The scanner turns on, but does not scan.

The SQUELCH con-trol is not correctly adjusted.

Adjust the SQUELCH control clockwise (see “Turning On the Scanner/Setting the Volume and Squelch”).

In the scan mode, the scanner locks on frequencies that have an unclear transmission.

You have programmed a “Birdie” frequency.

Avoid programming frequen-cies listed under “Finding Birdie Frequencies,” or only select them manually.

Poor or no reception. Improperly connected antenna.

Programmed frequen-cies are the same as Birdie frequencies.

The environment is not suitable for reception by the scanner.

Be sure the antenna is properly connected.

Avoid programming frequen-cies listed under “Finding Birdie Frequencies,” or only select them manually.

Relocate the scanner and try again.

Keys do not work or display changes at random.

Undetermined error. The CPU is locked up.

Reset or initialize the scanner (see “Resetting the Scanner’s Display” and “Initializing the Scanner”).

Error appears on the dis-play.

Programming error. Reprogram the frequency cor-rectly.

CARE AND MAINTENANCE

Your Radio Shack PRO-2040 100-Channel Programmable Home Scanner is anexample of superior design and craftsmanship. The following suggestions willhelp you care for your scanner so you can enjoy it for years.

Keep the scanner dry. If it gets wet, wipe it dry immediately. Liq-uids might contain minerals that can corrode the electronic cir-cuits.

Handle the scanner gently and carefully. Dropping it can damagecircuit boards and cases and can cause the scanner to work im-properly.

Use and store the scanner only in normal temperature environ-ments. Temperature extremes can shorten the life of electronicdevices and distort or melt plastic parts.

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

Wipe the scanner with a damp cloth occasionally to keep it lookingnew. Do not use harsh chemicals, cleaning solvents, or strong de-tergents to clean the scanner.

Modifying or tampering with the scanner’s internal components can cause a mal-function and might invalidate your scanner’s warranty and void your FCC autho-rization to operate it. If your scanner is not performing as it should, take it to yourlocal Radio Shack store for assistance.
