All Rights Reserved. Radio Shack is a registered trademark used by Tandy Corporation. Your Radio Shack PRO-2040 100- Channel Programmable Home Scan- ner lets you in on all the action! This scanner gives you direct access to over 30,000 exciting frequencies that include police and fire departments, ambulance and transportation ser- vices, and amateur radio. You can select up to 100 channels to scan, and you can change your selections at any time. The secret to your scanner’s ability to scan 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 channels per second. Hypersearch — searches through frequencies at 300 steps per second in bands that have 5 kHz steps to help you find interesting broadcasts. Ten 10-Channel Storage Banks — let you store 10 channels in each of 10 banks to group frequencies so you can easily identify calls. Priority Channel — checks a speci- fied channel every 2 seconds so you do not miss important calls. Data Detection — you can set it to detect data signals (nonmodulated signals such as preamble signals for pagers) during a limit or a direct search so it can automatically contin- ue searching. Monitor Memories — let you store up to 10 frequencies you locate dur- ing a frequency search which you can then transfer into channels. Search Function — searches for new and unlisted frequencies using a designated frequency range (limit search) or starting from a specified frequency (direct search). Selectable Scan/Search Speeds — let you select normal or hyper scan speeds, and normal, high, or hyper search speeds. Manual or Scan Channel Select — lets you manually specify a single channel or set the scanner to auto- matically scan all the stored chan- nels. Search Skip — lets you select up to 50 frequencies for the scanner to skip during a limit or direct search, so you can avoid unwanted frequen- cies. 20-414.fm Page 2 Wednesday, August 4, 1999 11:12 AM

scanning for 2 seconds before mov- ing to another channel, so you can hear more replies. Weather Band Key — scans the preprogrammed weather frequen- cies to keep you informed of the most current weather conditions. Memory Backup — keeps the chan- nel frequencies stored in your scan- ner’s memory for up to 3 days during a power loss. Squelch Control — lets you adjust the receiver’s sensitivity low enough to receive weak signals or high enough to eliminate receiver noise when not receiving a signal. Lock-Out Function — prevents channels you select from being scanned. Backlit LCD Display — lets you easily see the indicators on the scan- ner’s display, even at night. Audio Output Jack — lets you con- nect an earphone or headphones for private listening, or an external speaker for listening in a remote or noisy area. Optional Antenna Terminals — let you connect the supplied telescoping antenna to the screw-in terminal, or an external antenna to the BNC con- nector. Optional Power Sources — let you power your scanner using the sup- plied AC adapter or an optional DC adapter. Warning: To prevent fire or shock hazard, do not expose this system to rain or moisture.

You can hear police and fire depart- ments, ambulance services, government agencies, private companies, amateur radio services, aircraft, and military operations. It is legal to listen to almost every transmission your scanner can receive. However, there are some electronic and wire 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), as amended, you could be fined and possibly imprisoned for intentionally listening to, using, or disclosing the contents of such a transmission unless you have the consent 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 laws that also affect legal scanner usage. 20-414.fm Page 6 Wednesday, August 4, 1999 11:12 AM

You can power your scanner from a standard AC outlet using the sup- plied AC adapter. Warning: Do not use the AC adapt- er’s polarized plug with an extension cord receptacle unless the blades can be fully inserted to prevent blade exposure. Cautions: • The supplied AC adapter sup- plies 12 volts and delivers 500 milliamps. Its center tip is set to positive, and its plug properly fits the scanner’s DC 12V jack. Using an AC adapter that does not meet these specifications could damage the scanner or the adapter. The scanner’s dis- play dims if the AC adapter you use does not provide the required 12 volts DC. • Be sure you connect the AC adapter to the scanner before you connect it to a standard AC outlet. Then disconnect the adapter from the AC outlet before you disconnect it from the scanner. • If you have difficulty inserting the AC adapter’s polarized plug, do not force it. Turn it over and rein- sert it. 1. Insert the supplied AC adapter’s barrel plug into the scanner’s DC 12V 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 keeps information in memory for up to 3 days. Note: The memory backup circuit begins to protect the contents in memory within a few minutes after you plug in the scanner. 20-414.fm Page 7 Wednesday, August 4, 1999 11:12 AM

To power your scanner from your ve- hicle’s battery power, you need a DC power cord (such as Radio Shack Cat. No. 270-1533). Cautions: • Your vehicle must have a 12-volt DC, negative-ground electrical system. • The recommended DC power cord supplies 12 volts and deliv- ers at least 500 milliamps. The center tip on the barrel plug is set to positive, and the plug properly fits the scanner’s DC 12V jack. Using a DC power cord (or adapter) that does not meet these specifications could dam- age the scanner or the cord (or adapter). The scanner’s display dims if the DC cord (or adapter) you use does not provide the required 12 volts DC. • Be sure you connect the DC cord to the scanner before you connect it to the vehicle’s ciga- rette-lighter plug. Then discon- nect the cord from the vehicle’s cigarette-lighter plug before you disconnect it from the scanner. Follow these steps to use vehicle battery power. 1. Insert the barrel plug into the scanner’s DC 12V jack. 2. Plug the other end of the adapter 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 (or adapter) from the lighter socket and clean the socket to remove ashes and other debris. DC 12V Jack 20-414.fm Page 8 Wednesday, August 4, 1999 11:12 AM

telescoping antenna or an optional antenna. Telescoping Antenna To attach the telescoping antenna, simply screw it into the hole on top of your scanner. The antenna’s length controls its sensitivity. Adjust the length of the telescoping antenna as follows for the best reception. 29-54 MHz Extend all 3 seg- ments 108-174 MHz Extend only 2 seg- ments 406-956 MHz Collapse Fully (only 1 segment extend- ed) Optional Outdoor Antenna The supplied antenna is usually ade- quate for strong, local signals. How- ever, for the best results in receiving weaker, more distant signals on all bands, you can attach an optional outdoor antenna (not supplied), such as a mobile, telescoping, multi-band, or outdoor base antenna. Warning: When installing or remov- ing an outdoor antenna, follow all cautions and warnings included with the antenna. Notes: • This scanner uses a BNC antenna connector. If the coaxial cable’s connector does not fit the ANT jack, you might also need an adapter. Your local Radio Shack store sells a com- plete line of outdoor antennas, adapters, BNC connectors, and mounting hardware. • Always use 50-ohm coaxial cable to connect an outdoor antenna. For lengths under 50 feet, 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). 20-414.fm Page 9 Wednesday, August 4, 1999 11:12 AM

the following when deciding on an outdoor base antenna and its loca- tion: • The location of the external antenna should be as high as possible. • The external antenna and antenna cable should be as far away as possible from sources of electrical noise (appliances, other radios, and so on). • The external antenna should be vertical. Mount the antenna following the in- structions supplied with the antenna and its mounting hardware, then fol- low these steps to connect an exter- nal antenna. 1. Route the antenna cable to the scanner and connect it to the ANT jack on the back of the scanner. Caution: Do not route the cable over sharp edges or moving objects. 2. Remove the supplied antenna from the top of the scanner. RESETTING THE SCANNER’S DISPLAY If the scanner’s display locks up after you connect a power source, follow these steps to reset it. 1. If the scanner is off, press POWER to turn it on. 2. Using a pointed object, such as a straightened paper clip, press RESET on the back of the scan- ner. The display resets, and the scanner turns off. 3. Press POWER to turn on the scanner again. 20-414.fm Page 10 Wednesday, August 4, 1999 11:12 AM

work properly even after resetting it, follow these steps to initialize the scanner. Caution: Initializing the scanner clears all the channels you stored in memory. Initialize the scanner only when you are sure it is not working properly. 1. If the scanner is off, press POWER to turn it on. 2. Press and hold ./CLEAR, then press RESET on the back of the scanner using a pointed object, such as a straightened paper clip. The display resets, and the scanner turns off. 3. Press POWER to turn on the scanner. CONNECTING AN EARPHONE/ HEADPHONES/ EXTERNAL SPEAKER The 1/8-inch EXT SP jack on the back of the scanner lets you connect an earphone, headphones, or an exter- nal speaker. • For private listening, connect an earphone (Cat. No. 33-175). • For more comfortable private lis- tening, connect monaural head- phones (Cat. No. 20-210). • For listening from a remote area or in a noisy area, connect an extension speaker (Cat. No. 21- 549). Note: Connecting any external de- vice to the EXT SP jack automatically disconnects the internal speaker. 20-414.fm Page 11 Wednesday, August 4, 1999 11:12 AM

guidelines when you use an ear- phone or headphones. • Do not listen at extremely high volume 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, 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 wear an earphone or head- phones while operating a motor vehi- cle or riding a bicycle. This can create a traffic hazard and is illegal in some areas. Even though some earphones are designed to let you hear some out- side sounds when listening at normal volume levels, they still present a traffic hazard. 20-414.fm Page 12 Wednesday, August 4, 1999 11:12 AM

A LOOK AT THE FRONT PANEL This look at the scanner’s front panel will help you understand each control’s function. Control Function POWER Turns the scanner on and off. 1-0 Each single-digit number on the keys enters the numbers for a channel or a frequency, or each range of numbers above the number keys indicates the channels that make up a channel-storage bank. See “Understanding Channel-Storage Banks.” ./CLEAR Enters the decimal point in a frequency, or clears an incorrect entry and is used when you initialize the scanner. ENTER Enters programmed frequencies into channels. VOLUME Sets the scanner’s volume. SQUELCH Adjusts the scanner’s receiver sensitivity to help you eliminate background noise. SCAN Starts scanning through the stored channels. MANUAL Stops scanning and lets you manually enter a chan- nel number. 20-414.fm Page 13 Wednesday, August 4, 1999 11:12 AM

into your scanner’s memory. You store each frequency into either a memory called a channel, or a tem- porary memory called a monitor. This scanner has 100 channel memories and 10 monitor memories. Channel-Storage Banks To make it easier to identify and se- lect the channels you want to listen to, channels are divided into 10 chan- nel-storage banks of 10 channels each. Use each channel-storage bank to group frequencies, such as the police department, fire depart- ment, ambulance services, or aircraft (see “A Guide to the Action Bands”). For example, the police department might use four frequencies, one for each side of town. You could pro- gram the police frequencies starting with Channel 1 (the first channel in Bank 1) and program the fire depart- ment starting with Channel 11 (the first channel in Bank 2). Monitor Memories The scanner has 10 monitor memo- ries. You can use these memories to temporarily store frequencies while you decide whether or not to store them into channels. This is handy for quickly storing an active frequency when you search through an entire band. You can manually select these memories, but you cannot scan them. 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. 20-414.fm Page 17 Wednesday, August 4, 1999 11:12 AM

SCANNER/SETTING THE VOLUME AND SQUELCH 1. Turn SQUELCH fully clockwise. 2. Press POWER to turn on your scanner. The scanner continu- ously scans the unlocked chan- nels. Note: The first time you turn on the scanner, the channels might not have any frequencies stored in them, but the scanner will continuously scan the empty channels anyway. 3. Press MANUAL to stop the scan- ning. The display shows the cur- rent channel. 4. Turn VOLUME clockwise to set the scanner’s volume about 1/4 of the way between MIN and MAX. 5. Turn SQUELCH counterclock- wise until you hear a hissing noise. 20-414.fm Page 18 Wednesday, August 4, 1999 11:12 AM

level. 7. Slowly turn SQUELCH clockwise until the hissing noise stops. Squelch Tips: • If the scanner picks up unwanted or weak transmis- sions, slightly turn SQUELCH clockwise to decrease receiver sensitivity. • If the scanner does not pick up any transmissions, slightly turn SQUELCH counterclockwise to increase receiver sensitivity. FINDING BIRDIE FREQUENCIES Birdies are operating frequencies generated and used inside the scan- ner’s receiver. These operating fre- quencies could interfere with broadcasts on the same frequencies and make them difficult or impossible to receive. These are the most common birdies to watch for: 31.0500 MHz 134.550 MHz 127.2500 MHz 136.050 MHz 128.1875 MHz 138.050 MHz 128.2500 MHz 140.275 MHz 129.6875 MHz 144.900 MHz 132.0500 MHz 171.250 MHz 132.2625 MHz If you store one of these frequencies into a channel, you might hear only noise when the scanner stops on that frequency. If the interference is not severe, you might be able to turn SQUELCH clockwise to cut out the birdie. To find your scanner’s specific bird- ies: 1. Disconnect the antenna and move it away from the scanner. Note: Make sure that no other nearby radios or TVs are turned on. 2. Search every frequency band from its lowest frequency to the highest (see “Searching For and Temporarily Storing Active Fre- quencies”). If searching stops (as if the scanner had found a signal) but there is no sound, that frequency might be a birdie. For future reference, record all the birdies in your particular scanner. 20-414.fm Page 19 Wednesday, August 4, 1999 11:12 AM

quencies into your scanner’s chan- nels. Radio Shack sells some good references for active frequencies, such as “Police Call Radio Guide In- cluding Fire and Emergency Servic- es,” “Official Maritime Frequency Directory” and “Official Aeronautical Frequency Directory.” Radio Shack updates these directo- ries every year, so be sure to get a current copy. If you do not have a ref- erence to frequencies in your area, you can use a limit or direct search to find a transmission. Follow these steps to manually store frequencies. 1. Press MANUAL to stop the scan- ning. 2. Enter the channel number where you want to store a frequency. 3. Press PGM. 000.0000MHz PROGRAM, BANK, the bank number and the selected chan- nel number appear on the dis- play. 4. Enter the frequency you want to store, including the decimal point. Notes: • Frequencies are separated from each other in the follow- ing steps: • When you enter a frequency, the scanner automatically rounds it to the nearest valid number. For example, if you enter the frequency 151.473, your scanner rounds it up to 151.475. Frequencies Steps 29.0-108.0 MHz 5 kHz 108-136.975 MHz 12.5 kHz 137.0-300.0 MHz 5 kHz 300-3000 MHz 12.5 kHz 20-414.fm Page 20 Wednesday, August 4, 1999 11:12 AM

quency into the selected chan- nel. Note: If you made a mistake in Step 4, Error appears on the display. Repeat Steps 4 and 5. 6. To program the next channel in sequence, repeat Steps 3-5. To program other channels not in sequence, repeat Steps 2-5. SEARCHING FOR AND TEMPORARILY STORING ACTIVE FREQUENCIES You can search for frequencies using a limit or direct search, then either skip selected frequencies or tempo- rarily store frequencies into monitor memories. Limit Search A limit search lets you search for ac- tive transmissions within a specified range 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 a frequency appear on the display. 2. Using the number keys, enter the lowest frequency (including the decimal point) you want to search within the desired fre- quency range, then press ENTER. Note: If you enter an invalid fre- quency, Error appears on the display. To correct this, simply repeat the step. 20-414.fm Page 21 Wednesday, August 4, 1999 11:12 AM

appear on the display. 4. Using the number keys, enter the highest frequency you want to search within the desired fre- quency range, then press ENTER. 5. Press D to search upward from the lower to the upper limit, or press — to search downward from the upper to the lower limit. -L-, SEARCH, and s or t appear, and the next available monitor memory flashes on the display. 6. When the scanner finds an active frequency you want to monitor, you can do one of the following: • To store the displayed fre- quency into the current moni- tor memory, quickly press MON. • To continue the search, press D or —. To hold the frequency, press LIMIT. -H- appears on the dis- play. Press LIMIT again to exit the hold mode and resume the limit search. Notes: • If you press D or — during the hold mode, the frequency changes in the current step increment toward the upper or lower limits. • If you tune to a search skip frequency, the display shows LOCKOUT (see “Search Skip Memory”). Direct Search A direct search lets you specify a starting frequency, then search for active transmissions above or below the specified frequency. Note: You can use the scanner’s de- lay feature while using direct search (see “Delay”). 1. Press MANUAL. 20-414.fm Page 22 Wednesday, August 4, 1999 11:12 AM

the frequency (including the dec- imal point) you want to start the search from, or the channel number containing the starting frequency, then press MAN or PGM to select the channel. 3. Press D to search up or — to search down starting from the specified frequency or channel. -d-, SEARCH, and s or t appear, and the next available monitor memory flashes on the display. Note: If you enter an invalid fre- quency, Error appears on the display. To correct this, repeat Steps 2 and 3. 4. When the scanner finds an active frequency you want to monitor, you can do one of the following: • To store the frequency into the current monitor memory, press MON. • To continue the search, press D or —. • To hold the frequency, press LIMIT. -h- appears on the display. • Press LIMIT again to exit the hold mode and resume the direct search. Notes: • If you press D or — during the hold mode, the frequency changes in the current step increment toward the upper or lower limits. • If you tune to a search skip frequency, the display shows LOCKOUT (see “Search Skip Memory”). Search Skip Memory You can skip specified frequencies during a limit or direct search. This lets you avoid unwanted frequencies or ones you have already stored in a channel. You can program up to 50 skip frequencies into the scanner’s memory. 20-414.fm Page 23 Wednesday, August 4, 1999 11:12 AM

SEARCH SKIP when the scanner stops on the frequency during a limit or direct search. To clear a single frequency from skip memory so the scanner can stop on it during a limit or direct search, press LIMIT to hold the search, press D or — to select the skipped frequency, then press L/O/SEARCH SKIP until LOCKOUT disappears from the dis- play. To clear all the skip frequencies at once, while in the search mode, press and hold L/O/SEARCH SKIP un- til the scanner beeps twice. Notes: • If you program more than 50 skip 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 in the hold mode. The scanner dis- plays LOCKOUT when you select 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 by pressing MANUAL, MON, then the number for the monitor memory you want to listen to. Note: To listen to the monitor memo- ries, the priority channel feature must be turned off (see “Designating a Pri- ority Channel”). 20-414.fm Page 24 Wednesday, August 4, 1999 11:12 AM

FROM A MONITOR MEMORY TO A CHANNEL 1. Press MANUAL to stop the scanning. 2. Enter the channel number where you want to store the monitor frequency, then press PGM. PROGRAM appears on the dis- play. 3. Press MON, then enter the moni- tor memory number that has the frequency you want to store into the channel. MON and the entered frequency appear, and the channel number blinks on the display. 4. Press ENTER. The scanner stores the frequency into the selected channel. SCANNING THE STORED CHANNELS To scan the stored channels, press SCAN. Your scanner scans through all the stored channels except the ones you lock out (see “Locking Out Channels”). If needed, readjust SQUELCH so you do not hear the hissing sound be- tween transmissions. 20-414.fm Page 25 Wednesday, August 4, 1999 11:12 AM

You can set your scanner to scan more efficiently by turning selected channel storage banks on and off. When you turn off a bank, the scan- ner does not scan any of the 10 channels in the bank. While scanning, press the number key corresponding to the bank you want to turn on or off. If the memory bank indicator is on, the bank is turned on and the scanner scans all channels within that bank that are not locked out. If the indicator is off, the scanner does not scan any of the channels within that bank. Notes: • You can manually select any channel in a bank, even if the bank is turned off. • You cannot turn off all banks. There must be at least one active bank. MANUALLY SELECTING A CHANNEL You can continuously monitor a spe- cific channel without scanning. This is useful if you hear an emergency broadcast on a channel and want to hear all the details (even though there might be periods of silence) or if you want to monitor only a specific channel or a locked-out channel. To manually select a channel, press MANUAL, enter the channel number, then press MANUAL again. If scanning has stopped at the de- sired channel, simply press MANUAL once. Repeatedly press MANUAL to step through the channels one at a time. 20-414.fm Page 26 Wednesday, August 4, 1999 11:12 AM

WEATHER BAND The FCC (Federal Communications Commission) has allocated 11 chan- nels for use by the National Oceanic and Atmospheric Administration (NOAA). Your scanner is preprogrammed with the following frequencies available to NOAA. 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, simply press WX. WX appears on the dis- play. Your scanner searches through the weather band and stops on an active broadcast. If a broadcast is weak, press WX again to continue to search through the weather band. 20-414.fm Page 27 Wednesday, August 4, 1999 11:12 AM

you can scan through the pro- grammed channels and still not miss an important or interesting call on a specific channel. Note: You can select only one chan- nel as the priority channel. To program a stored channel as the priority channel, press PGM, the de- sired stored channel number, then PRI/HYPER SEARCH. P appears on the display. To turn on the priority feature, press PRI/HYPER SEARCH during scan- ning. PRIORITY appears on the display. The scanner now checks the priority channel every 2 seconds, and stays on the channel if there is activity. P appears on the display whenever the scanner is set to the priority channel. To turn off the priority feature, press PRI/HYPER SEARCH until PRIORI- TY disappears from the display. USING THE 2-SECOND DELAY Many agencies use a two-way radio system that might have a period of several seconds between a query and a reply. To avoid missing a reply, you can program a 2-second delay into any channel. When the scanner stops on an active channel with a programmed delay, it continues to monitor the channel for 2 seconds af- ter the activity stops before resuming scanning. To program a 2-second delay into a specific channel, manually select the desired channel then press DLY. DE- LAY appears on the display. To program a 2-second delay when the scanner stops on an active chan- nel during scanning, quickly press DLY while the channel is still active. DELAY appears on the display. To turn off the programmed delay on any active channel, press DLY while the channel is still active. DELAY dis- appears from the display. 20-414.fm Page 28 Wednesday, August 4, 1999 11:12 AM

more efficiently by locking out chan- nels you do not want to monitor. This is handy for locking out channels where you stored a frequency with a continuous transmission, such as a weather channel. To lock out a channel, press MANU- AL, enter the desired channel num- ber, press MAN or PGM to select the channel, then press L/O/SEARCH SKIP so LOCKOUT appears on the display. Notes: • You can still manually select locked out channels. • You cannot lock out all channels. There must be at least one active channel in each bank. To unlock a channel, manually select the channel, then press L/O/SEARCH SKIP so LOCKOUT disappears from the display. To unlock all channels, while the scanner is scanning, select the banks containing the locked chan- nels you want to unlock, press MAN- UAL, then press and hold L/O/ SEARCH SKIP until the scanner beeps twice. CHANGING SCANNING AND SEARCH SPEEDS The PRO-2040 has two scan and three search speeds. To change the scanning speed, dur- ing scanning, press SPEED to switch between normal and hyper scan speeds. SCAN flashes on the display during hyper scan speed. Notes: • You can also change the search speeds when you listen to the weather band. • s or t flashes on the display dur- ing high speed search. Type Speed Normal Scan Hyper Scan 12 channels/second 50 channels/second Normal Search High Speed Search Hyper Search 50 steps/second 100 steps/second 300 steps/second 20-414.fm Page 29 Wednesday, August 4, 1999 11:12 AM

a limit or direct search, press SPEED to switch between the normal and high speed search speeds. s or t flashes on the display during high speed search. To select the hyper search speed, during a limit or direct search, press PRI/HYPER SEARCH. SEARCH flash- es on the display during hyper search speed. Note: You can use hyper search speed only in 5 kHz-step bands. DETECTING DATA SIGNALS You can set the scanner to detect data signals (nonmodulated signals such as preamble signals for pagers) during a limit or direct search. Note: You cannot detect data signals in the air band (AM mode). To detect data signals, press DATA so DATA appears on the display. If the scanner momentarily pauses on a transmission and detects a data signal, it resumes searching in 2 or 3 seconds. To stop detecting data signals, press DATA so DATA disappears from the display. 20-414.fm Page 30 Wednesday, August 4, 1999 11:12 AM

Reception of the frequencies cov- ered by your scanner is mainly “line- of-sight.” That means you usually cannot hear stations that are beyond the horizon. During the summer months, you might be able to hear stations in the 30-50 MHz range lo- cated several hundred or even thou- sands of miles away. This is because of summer atmospheric conditions. This type of reception is unpredict- able but often very interesting!

The following chart shows the frequencies that Hams use: GUIDE TO THE ACTION BANDS International Broadcast Bands Several shortwave bands are allocat- ed for international broadcasting be- cause of the nature of propagation of high frequencies. The bands are sometimes identified according to the approximate wavelength of the signals in meters. Wavelength (meters) Frequency (MHz) 10-meter 28.000–29.700 6-meter 50.000–54.000 2-meter 144.000–148.000 70-cm 420.000–450.000 Wavelength (meters) Frequency (MHz) 20-414.fm Page 31 Wednesday, August 4, 1999 11:12 AM

their associated base stations and relay repeater units. Specified Intervals Frequencies in different bands are accessible only at specific intervals. For example: Note: Your scanner rounds the entered frequency to the nearest valid frequency. For example, if you try to enter 151.473, the scanner accepts this as 151.475. Band Allocation To help decide which frequency ranges to search, use the following listing of the typical services that use the frequencies your scanner receives. These frequen- cies are subject to change, and might vary from area to area.

GTR 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 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 20-414.fm Page 38 Wednesday, August 4, 1999 11:12 AM

should require very little maintenance. If you have problems, refer to this chart for possible solutions. If you cannot solve the problem, contact your local Radio Shack store for assistance. Problem Probable Cause Solution Scanner 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. 20-414.fm Page 39 Wednesday, August 4, 1999 11:12 AM

Your Radio Shack PRO-2040 100-Channel Programmable Home 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. Liq- uids might contain minerals that can corrode the electronic cir- cuits. Handle the scanner gently and carefully. Dropping it can damage circuit 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 electronic devices 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 looking new. 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.
