20-418.fm Page 1 Wednesday, August 4, 1999 12:42 PM Cat. No. 20-418 OWNER’S MANUAL PRO-2045 200-Channel Weather Alert Home Scanner Please read before using this equipment. 20-418.fm Page 2 Wednesday, August 4, 1999 12:42 PM FEATURES Your RadioShack PRO-2045 200Channel Weather Alert Home Scanner lets you in on all the action! This scanner gives you direct access to over 49,500 exciting frequencies used by police and fire departments, ambulance and transportation services, amateur radio, as well as aircraft communications, Citizen’s Band, and commercial FM and television broadcasts. You can select up to 200 channels for your scanner to scan, and you can change your selections at any time. Its rotary tuning control lets you easily select frequencies and channels. Plus, when you turn on the weather alert function, the scanner sounds an alarm if the weather service transmits a weather alert tone. Hyperscan — scans programmed channels at up to 50 channels per second. Hypersearch — lets you set the scanner to search at up to 300 steps per second. Rotary Tuner — lets you easily tune and select frequencies or channels. Auto Sort — lets you scan the channels stored in a bank, in order from lowest to highest frequency, to increase scanning speed. Auto Store — quickly finds and automatically stores active frequencies into the selected banks (but does not store the frequency if it is already stored in another channel). The secret to your scanner’s ability to scan so many frequencies is its custom-designed microprocessor — a tiny, built-in computer. Ten Channel-Storage Banks — let you store 20 channels in each of 10 banks to group frequencies so you can easily identify calls. Your scanner has these features: Frequency Transfer — lets you easily organize your frequencies by transferring them from one channel to another. WX Alert — warns you of serious weather conditions by sounding an alarm if the weather service transmits a weather alert tone. Weather Band Auto Scan — scans the preprogrammed weather frequencies so you can stay informed about current weather conditions. Monitor Memories — let you store up to 10 frequencies you locate during a frequency search. Limit Search — lets you search for transmissions within a set range. © 1996 Tandy Corporation.

Attenuator — reduces the scanner’s sensitivity to help limit reception to strong, nearby transmitters. Count Feature — lets you keep track of how many times your scanner has stopped on a channel. Memory Backup — keeps stored channel frequencies in memory for up to 3 days during a power loss. Search Skip — lets you select up to 50 frequencies for the scanner to skip during a search, so you can avoid frequencies you have already discovered or that have a continuous transmission. CTCSS Option — with an optional CTCSS tone circuit board, you can use the Continuous Tone Coded Squelch System (CTCSS) to selectively listen to some business band and amateur radio transmissions. Two-Second Scan Delay — delays scanning for 2 seconds before moving to another channel, so you can hear more replies. Backlit Display — lets you easily see the indicators on the scanner’s display, even at night. Data Skip — skips data signals (nonmodulated signals such as preamble signals for pagers) during scan, limit search, and direct search. Lock-Out Function — prevents channels you select from being scanned. Priority Channels — checks 10 specified channels every 2 seconds so you do not miss important calls. We recommend you record your scanner’s serial number here. The number is on the scanner’s back panel. Serial Number: _________________ Your scanner has the following preprogrammed weather channels: • 162.4000 MHz (NFM) • 162.4250 MHz (NFM) • 162.4500 MHz (NFM) • 162.4750 MHz (NFM) Automatic Modulation Mode — selects the modulation method — narrow-band frequency modulation (NFM) or amplitude modulation (AM) — most often used for each band, and lets you manually override the preset mode. • 162.5000 MHz (NFM) • 162.5250 MHz (NFM) • 162.5500 MHz (NFM) 3 20-418.fm Page 4 Wednesday, August 4, 1999 12:42 PM Your scanner can receive all of these bands: Range (MHz) Step (kHz) Mode 29–54 5 NFM 108–136.975 12.5 AM 137–174 5 NFM 216–224.9875 12.5 NFM 225–399.9875 12.5 AM 400–512 12.5 NFM 806–823.9375 12.5 NFM 851–868.9375 12.5 NFM 896.1125–1,000 12.5 NFM FCC NOTICE Your scanner might cause radio or TV interference even when it is operating properly. To determine if your scanner is causing the interference, turn off your scanner. If the interference goes away, your scanner was causing it. Try to eliminate the interference by: • Moving your scanner away from the receiver • Connecting your scanner to an outlet that is on a different electrical circuit from the receiver • Contacting a RadioShack store for help If you cannot eliminate the interference, the FCC requires that you stop using your scanner. 4 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 transmission 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 transmissions or encrypted 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 conversation (unless such activity is otherwise illegal). RadioShack encourages responsible, legal scanner use. 20-418.fm Page 5 Wednesday, August 4, 1999 12:42 PM CONTENTS Preparation . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 7 Connecting Power . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 7 Using Standard AC Power . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 7 Using Vehicle Battery Power . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 7 Connecting an Antenna . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 8 Telescoping Antenna . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 8 Optional Outdoor Antenna . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 8 Resetting the Scanner . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 9 Using the Feet . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 9 Testing Alert Operation . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 10 Testing Alert Reception . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 10 Testing the Weather Alert . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 11 Connecting an Earphone . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 11 Listening Safely . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 11 Traffic Safety . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 12 Connecting an Amplified Extension Speaker . . . . . . . . . . . . . . . . . . . . . . . . 12 Installing an Optional CTCSS Tone Board . . . . . . . . . . . . . . . . . . . . . . . . . . 12 Understanding Your Scanner . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

You can power your scanner from a standard AC outlet using the supplied AC adapter or from your vehicle’s battery using an optional DC power cord. If a power failure occurs or if the power cord is disconnected, the scanner’s memory backup circuit keeps information in memory for up to 3 days. Note: The memory backup circuit begins to protect memory within a few minutes after you plug in the scanner. DC 12V 1. Insert the supplied AC adapter’s barrel plug into the scanner’s DC 12V jack. 2. Plug the adapter’s power module into a standard AC outlet. Using Standard AC Power Using Vehicle Battery Power Warning: Do not use the AC adapter with an extension cord unless the blades can be fully inserted. Use a DC power cord (not supplied), such as RadioShack Cat. No. 2701533, to power your scanner in your vehicle. Cautions: • The supplied AC adapter supplies 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. • Connect the adapter to the scanner before you connect it to an AC outlet. Disconnect the adapter from the AC outlet before you disconnect it from the scanner. • If you have difficulty inserting the AC adapter’s plug, do not force it. Turn it over and reinsert it. Cautions: • The DC power cord you select must supply 12 volts and deliver at least 500 mA. Its center tip must be positive, and its plug must fit the scanner’s DC 12V jack. The recommended power cord meets these specifications. Using a power cord that does not meet these specifications could damage the scanner or power cord. • Connect the power cord to the scanner before you plug it into your vehicle. Disconnect the power cord from the vehicle before you disconnect it from the scanner. 7 20-418.fm Page 8 Wednesday, August 4, 1999 12:42 PM • If you use your scanner in your vehicle with the engine running, you might hear electrical noise from the scanner. This is normal. Note: Mobile use of this scanner is unlawful or requires a permit in some areas. Check the laws in your area. Follow these steps to use vehicle battery power. DC 12V ANT 1. Hold the antenna so it stands straight up. 2. Gently push the antenna’s plug onto the ANT jack on the scanner’s back panel. The antenna’s length affects reception. Adjust the antenna’s length as follows for the best results. 29–150 MHz Extend fully 150–174 MHz 1. Insert the DC power cord’s barrel plug into the scanner’s DC 12V jack. Extend only 3 segments 216–406 MHz Extend only 2 segments 2. Plug the DC power cord’s cigarette-lighter plug into your vehicle’s cigarette-lighter socket. 406–1000 MHz Collapse Fully (only 1 segment extended) Optional Outdoor Antenna CONNECTING AN ANTENNA Telescoping Antenna The supplied antenna is usually good for strong, local signals. However, 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. The supplied telescoping antenna helps your scanner receive strong local signals. Follow these steps to install the supplied antenna. Warning: When installing or removing an outdoor antenna, follow all cautions and warnings included with the antenna. You can connect either the supplied telescoping antenna or an optional antenna to your scanner. 8 20-418.fm Page 9 Wednesday, August 4, 1999 12:42 PM Note: Always use 50-ohm coaxial cable to connect an outdoor antenna to your scanner. For lengths under 50 feet, use RG-58 or RG-8/M coaxial cable. For lengths over 50 feet, use RG8, low-loss coaxial cable. If the coaxial cable’s connector does not fit the ANT jack, you might also need an adapter. Your local RadioShack store sells a complete line of outdoor antennas, adapters, BNC connectors, and mounting hardware. For the best performance, consider the following when deciding on an outdoor antenna and its location: RESETTING THE SCANNER If the scanner’s display locks up or does not work properly after you connect power or after a power surge, you might need to reset the scanner. Caution: This procedure clears all the information you have programmed into the scanner. Use this procedure only when you are sure your scanner is not working properly. • 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 instructions supplied with the antenna and its mounting hardware, then route the antenna cable to the scanner and connect it to the ANT jack on the back of the scanner. 1. Turn off the scanner. 2. While you press and hold down 2 and 9, turn on the scanner. USING THE FEET To tilt the display for the best viewing angle and to provide the best traction, pull down on the scanner’s feet so they lock into place. ANT 9 20-418.fm Page 10 Wednesday, August 4, 1999 12:42 PM TESTING ALERT OPERATION For your scanner’s weather alert function to be effective, you must place the scanner: • Where it can receive an emergency alert broadcast (see “Testing 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 that meets these two conditions, leave the scanner there for the best protection. Testing Alert Reception The fact that you get clear voice reception or that the tone sounds when you test the weather alert does not guarantee that an emergency alert broadcast will trigger your scanner’s alert tone. Also, if you are in a fringe area, your scanner might be triggered by a broadcast in one area, but not be triggered if you place it somewhere else (even close by). To test for actual reception, your radio must receive a test or emergency alert broadcast. The National Weather Service (NWS) broadcasts a test alert every week on Wednesday between 11 AM and 12 Noon. To find out the specific test schedule in your area, contact your local National Oceanic and Atmospheric Administration (NOAA) or National Weather Service office. 10 These offices are usually listed in the telephone book under “US Government, Department of Commerce.” To verify that your scanner receives the test alert properly, set the scanner to the weather alert standby mode (see “Using the Weather Alert Standby Mode” on Page 25) during the time when the test alert is broadcast in your area. If the test alert broadcast does not trigger your scanner’s tone, you are out of range of the broadcast. Note: If you use your scanner’s weather alert feature when you travel, you cannot guarantee that an emergency alert broadcast will trigger the scanner in all areas. Notes for Weather Alerts: • To ensure your scanner will sound the alert tone when it receives an emergency signal, keep the antenna fully extended at all times. • If severe weather threatens, do not wait for an alert tone; turn on your scanner and monitor the latest weather information. 20-418.fm Page 11 Wednesday, August 4, 1999 12:42 PM Testing the Weather Alert scanner. This disconnects the internal speaker. Follow these steps to test the weather alert — to hear how it sounds and ensure that the circuitry is working. Note: This test does not ensure that your scanner will sound an alert when the weather service transmits an emergency signal (see “Weather Alert” on Page 25). Proper operation is affected by the strength of the weather service’s signal. Note: Your local RadioShack store has a wide selection of earphones and headphones. Listening Safely 1. Press WX . 2. When the scanner stops on a weather channel, press ALERT. ALERT appears on the display. 3. Press and hold PRIORITY for more than 2 seconds until the scanner sounds a loud alarm. To turn off the alarm, press ALERT or WX . CONNECTING AN EARPHONE For private listening, plug an earphone or mono headphones’ 1/8-inch plug into the jack on the front of the To protect your hearing, follow these guidelines when you use an earphone or headphone. • 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. 11 20-418.fm Page 12 Wednesday, August 4, 1999 12:42 PM Traffic Safety Do not wear an earphone or headphones while operating a motor vehicle. This can create a traffic hazard and can be illegal in some areas. Even though some earphones and headphones let you hear some outside sounds when listening at normal volume levels, they still can present a traffic hazard. INSTALLING AN OPTIONAL CTCSS TONE BOARD The scanner’s CTCSS (Continuous Tone Control Squelch System) feature lets you choose to listen only to transmissions that transmit one of 38 standard CTCSS tones. To use CTCSS, you must install an optional CTCSS tone board (Cat. No. 20-0031). Cautions: CONNECTING AN AMPLIFIED EXTENSION SPEAKER In a noisy area, an amplified extension speaker might provide more comfortable listening. Plug the speaker cable’s 1/8-inch (3.5 mm) mini plug into the scanner’s jack. This disconnects the internal speaker. Note: RadioShack stores sell an amplified communications extension speaker. 12 • Make sure the scanner is off and disconnect the power before you install a CTCSS tone board. • Discharge static electricity buildup by touching a metal object before you open the scanner. 1. Use a Phillips screwdriver to remove the two side screws on the scanner’s top cover and three screws on the bottom. Caution: The scanner’s speaker is attached to the top cover and the circuit board. Use care when you remove the top cover to not damage the speaker or its connector. 20-418.fm Page 13 Wednesday, August 4, 1999 12:42 PM 2. Remove the scanner’s top cover. 3. Gently plug the CTCSS board into sockets J9 and J10 on the top of the scanner’s circuit board. CTCSS Board CTCSS BORD 4. Replace the scanner’s top cover, then replace the two side screws and three bottom screws. Note: For information about using CTCSS, see “Using CTCSS” on Page 30. 13 20-418.fm Page 14 Wednesday, August 4, 1999 12:42 PM UNDERSTANDING YOUR SCANNER A LOOK AT THE KEYBOARD A quick glance at this section should help you understand each key’s function(s).

Also, the indicator appears when you turn on the delay feature during a limit or direct search or weather scan. WX — appears when the scanner is searching the weather band frequencies. ALERT — appears when the scanner is set to respond to a weather alert tone. s and t — indicate the search direction. SEARCH — appears during a limit search ( -L- also appears), direct frequency search ( -d- also appears), weather frequency search, auto store mode, hold direct search (-h- also appears), and hold limit search ( -Halso appears). UNDERSTANDING CHANNEL-STORAGE BANKS Channel-Storage Banks To make it easier to identify and select the channels you want to listen to, channels are divided into 10 channelstorage banks of 20 channels each. Use each channel-storage bank to group frequencies, such as the police department, the fire department, ambulance services, or aircraft (see “Guide to the Action Bands” on Page 34). For example, the police department might use four frequencies, one for each side of town. You could program the police frequencies starting with Channel 1 (the first channel in Bank 1) and then program fire department frequencies starting with Channel 21 (the first channel in Bank 2). MONITOR MEMORIES The scanner also has 10 monitor memories. You can use these memories to temporarily store frequencies while you decide whether or not to save them into channels. This is handy for quickly storing an active frequency when you search through an entire band. See “Searching For and Temporarily Storing Active Frequencies” on Page 19. You can store up to 210 frequencies into your scanner’s memory. You store each frequency into either a memory called a channel, or a temporary memory called a monitor. This scanner has 200 channel memories and 10 monitor memories. 17 20-418.fm Page 18 Wednesday, August 4, 1999 12:42 PM OPERATION TURNING ON THE SCANNER/SETTING VOLUME AND SQUELCH 1. Rotate VOLUME 1/4 turn clockwise to turn on the scanner. 2. Rotate SQUELCH fully counterclockwise. 3. Slowly turn SQUELCH clockwise until the hissing stops. STORING FREQUENCIES You can store up to 200 frequencies into your scanner’s channels. Good frequency references are RadioShack’s “Police Call Guide including Fire and Emergency Services,” “Official Aeronautical Frequency Directory,” and “Maritime Frequency Directory.” These directories are updated every year, so be sure to get a current copy. Note: To hear a weak or distant station, turn SQUELCH counterclockwise. You might hear hissing, but you will not miss any transmissions. If you turn SQUELCH too far counterclockwise, the scanner does not search or scan. If you do not have a frequency reference for your area, you can use a limit or direct search to find transmissions. See “Searching For and Temporarily Storing Active Frequencies” on Page 19 or “Guide to the Action Bands” on Page 34. USING THE ROTARY CONTROL Follow these steps to manually store frequencies. The rotary control has three modes that you select using the FREQ/CHANLOCK button. To select the control’s mode, repeatedly press FREQ/CHANLOCK until the scanner displays the desired mode. FREQ — the rotary control steps through frequencies during a search. CHAN — the rotary control steps through the programmed channels. LOCK — the rotary control does not operate. Use this setting to help prevent accidentally changing the channel or frequency. 18 1. Press PROGRAM. PGM appears on the display. 2. Enter the number for the channel where you want to store a frequency. Note: You can enter the channel number using any of the following methods: • Use the number keys to enter the channel number, then press PROGRAM. • Press PROGRAM to increment the channel number one step at a time. 20-418.fm Page 19 Wednesday, August 4, 1999 12:42 PM • Press FREQ/CHAN-LOCK until the CHAN indicator appears.

To stop storing frequencies, press MANUAL. When all channels fill, the scanner beeps twice and End appears. Press MANUAL to display the channel where the last frequency was stored. 20-418.fm Page 23 Wednesday, August 4, 1999 12:42 PM LISTENING TO MONITOR MEMORIES Once you store frequencies into monitor memories using a direct or limit search or weather scan, you can listen to a monitor memory by pressing MANUAL , MONITOR, and then the number for the monitor memory you want to listen to. Note: To listen to the monitor memories, the priority channel feature must be turned off. MOVING A FREQUENCY FROM A MONITOR MEMORY TO A CHANNEL 1. Press PROGRAM. 2. Enter the channel number where you want to store the frequency, then press PROGRAM. PGM appears on the display. 3. Press MONITOR. Use the number keys or turn the rotary tuner to select the monitor memory’s number. The channel number flashes and the frequency appears. 4. Press E. The scanner stores the frequency into the selected channel. SCANNING CHANNELS To begin scanning channels, press SCAN. The scanner scans through all non-locked channels in the activated banks. (See “Turning Channel-Storage Banks On and Off” below and “Locking Out Channels” on Page 25.) Note: If the scanner does not scan, be sure you have set SQUELCH correctly. Turning Channel-Storage Banks On and Off You can turn each channel-storage bank on and off. When you turn off a bank, the scanner does not scan any of the 20 channels in that bank. While scanning, press the number key corresponding to the bank you want to turn on or off. If the memory bank number at the top of the display is on, the bank is turned on and the scanner scans all channels within that bank that are not locked out. If the number 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. • There must be at least one active bank. You cannot turn off all banks. 23 20-418.fm Page 24 Wednesday, August 4, 1999 12:42 PM Locking Out Channels You can increase the effective scanning speed by locking out channels that have a continuous transmission, such as a weather channel. Note: You can manually select the channels you have locked out. To lock out a channel, manually select the channel, then press LOCKOUT so L/O appears on the display. To review the locked-out channels, manually select the first channel you want to review. Then repeatedly press REVIEW to see the locked-out channels in sequence.

To store the current weather channel in a monitor memory, press MONITOR . Weather Alert Your scanner’s weather alert feature can warn you when your local NOAA weather station broadcasts a severe weather emergency signal. (See “Testing Alert Operation” on Page 10.) When NOAA broadcasts a severe weather emergency signal, the scanner sounds a loud alarm (regardless of the volume control setting). The alarm continues until the emergency signal stops transmitting. To manually turn off the siren and exit the weather alert mode, press ALERT or WX . Using the Weather Alert Standby Mode When you set the scanner to the weather alert standby mode, the scanner’s display and speaker turn off until the scanner receives the severe weather emergency signal. When the scanner receives the signal, it sounds a loud alarm. To set the scanner to the weather alert standby mode, follow these steps. 1. Press WX. 2. When the scanner stops on a weather channel, press ALERT for 2 seconds. The scanner displays on ALErt for 10 seconds, then the display turns off and your scanner is in the weather alert standby mode. To exit the weather alert standby mode, press ALERT or WX . 25 20-418.fm Page 26 Wednesday, August 4, 1999 12:42 PM SPECIAL FEATURES DELAY PRIORITY Many agencies use a two-way radio system that might have a period of 2 or more seconds between a query and a reply. To keep from missing a reply on a specific channel, you can program a 2-second delay into any channel, or on frequencies during a frequency search. The scanner continues to monitor the frequency for 2 seconds after the transmission stops before resuming scanning. The priority feature lets you scan through channels and still not miss important or interesting calls on specific channels. You can program one stored channel in each bank as a priority channel (up to 10 stored channels). As the scanner scans the banks, it checks the priority channels every 2 seconds for activity. To program a 2-second delay: • If the scanner is scanning and stops on an active channel, quickly press DELAY before it continues scanning again. • If the desired channel is not selected, manually select the channel, then press DELAY. • If the scanner is searching, press DELAY while the scanner is searching. DLY appears on the display and the scanner automatically adds a 2-second delay to every transmission it stops on. To turn off the 2-second delay, press DELAY while the scanner is monitoring the channel or while the scanner is searching. DLY disappears from the display. 26 Notes: • You cannot use the priority and data skip features at the same time. • You cannot use the priority and count features at the same time. • You can lock out priority channels. If you lock out all priority channels, the display shows LOC OUt when you turn on the priority feature. • The priority feature must be turned off to listen to monitor memories. • The scanner checks the lowestnumbered priority channels first. If it detects a transmission on a priority channel, it stays on that channel and does not check the other priority channels until the transmission ends. 20-418.fm Page 27 Wednesday, August 4, 1999 12:42 PM The scanner automatically designates each bank’s first channel as that bank’s priority channel.

While the scanner is scanning, press MANUAL. 2. Press COUNT. The scanner displays COUNT, the current channel number, and the count number. 3. Repeatedly press MANUAL to display each channel and the number of times the scanner detected a transmission on that channel. Note: If CHAN is on the display, you can use the rotary tuner instead of pressing MANUAL to display the channel count. While you view the count for a channel, you can zero the count by pressing CLEAR. To turn off the count display, press COUNT until COUNT disappears. USING CTCSS CTCSS is frequently used when two different services or groups use the same frequencies, but are relatively close together. Each group sets their transmitters to different CTCSS frequencies, and sets their receivers to only let them hear transmissions that include the correct CTCSS frequency. 30 This helps to avoid radio interference between the groups. You can use the CTCSS feature to lock out undesired transmissions and monitor only those which transmit a specific CTCSS tone. Note: You must install a CTCSS tone board before you can use this feature. “Installing an Optional CTCSS Tone Board” on Page 12. CTCSS Tone Frequencies The following table shows the available CTCSS tone frequencies and the letter codes commonly used in the industry to refer to the frequencies: XZ 67.0 1B 107.2 6Z 167.9 XA 71.9 2E 110.9 6A 173.8 WA 74.4 2A 114.8 6B 179.9 XB 77.0 2B 118.8 7Z 186.2 WB 79.7 3Z 123.0 7A 192.8 YZ 82.5 3A 127.3 M1 203.5 YA 85.4 3B 131.8 M2 210.7 YB 88.5 4Z 136.5 M3 218.1 ZZ 91.5 4A 141.3 M4 225.7 ZA 94.8 4B 146.2 M5 233.6 ZB 97.4 5Z 151.4 M6 241.8 1Z 100.0 5A 156.7 M7 250.3 1A 103.5 5B 162.2 20-418.fm Page 31 Wednesday, August 4, 1999 12:42 PM Assigning a CTCSS Tone Frequency to a Channel You can specify the CTCSS tone frequency you want the scanner to detect on a specific preprogrammed channel.

During the summer months, you might be able to hear stations in the 30–50 MHz range located several hundred or even thousands of miles away. This is because of summer atmospheric con- GUIDE TO FREQUENCIES National Weather Service Frequencies 161.650 MHz 162.425 MHz 162.475 MHz 162.550 MHz 161.775 MHz 162.440 MHz 162.500 MHz 163.275 MHz 162.400 MHz 162.450 MHz 162.525 MHz Ham Radio Frequencies Ham radio operators often broadcast emergency information when other means of communication break down. The following chart shows the voice frequencies that you can monitor. Wavelength Voice Frequency (MHz) 10-meter 29.000 29.700 6-meter 50.100 54.000 2-meter 144.100 148.000 11/4-meter 222.000 225.000 70-centimeter 420.000 450.000 33-centimeter 902.000 928.000 32 ditions. This type of reception is unpredictable but often very interesting! 20-418.fm Page 33 Wednesday, August 4, 1999 12:42 PM Birdie Frequencies Birdies are frequencies your scanner uses when it operates. These operating frequencies might interfere with broadcasts on the same frequencies. If you tune one of these frequencies, you hear only noise on that frequency. If the interference is not severe, you might be able to turn SQUELCH clockwise to cut out the birdie. Here are this scanner’s birdie frequencies that you might want to watch for: 29.4900 114.6875 147.4550 405.6000 29.4950 117.9625 147.4600 416.0000 31.2000 124.5250 150.9100 417.1000 36.0450 127.8000 155.1050 456.9260 52.0000 131.0750 156.0000 469.5000 52.4300 134.3500 228.4625 813.4000 108.1375 135.2000 230.5625 820.1125 108.8125 137.6250 232.1000 940.9000 111.4125 140.9050 398.2375 993.5000 114.4000 144.1800 To find the birdies in any receiver, begin by disconnecting the antenna and moving it away from the receiver. Make sure that no other nearby radio or TV sets are turned on near the receiver. Use the search function and search every frequency range from its lowest frequency to the highest. Occasionally, the searching 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. 33 20-418.fm Page 34 Wednesday, August 4, 1999 12:42 PM GUIDE TO THE ACTION BANDS Typical Band Usage HF Band (29.00–30.0 MHz) 10-Meter Amateur ................................................................. 29.00–29.70 MHz VHF Band (30.00–300.0 MHz) Low Range ............................................................................ 29.70–50.00 MHz 6-Meter Amateur ................................................................... 50.00–54.00 MHz Aircraft ............................................................................... 108.00–136.98 MHz U.S. Government .............................................................. 137.00–144.00 MHz 2-Meter Amateur ............................................................... 144.00–148.00 MHz High Range ....................................................................... 148.00–174.00 MHz New Mobile Narrow Band ................................................. 220.00–222.00 MHz 11/4 -Meter Amateur........................................................... 222.00–225.00 MHz Military Aircraft .................................................................. 225.00–287.80 MHz UHF Band (300.00 MHz–3.0 GHz) Military Aircraft .................................................................. 311.00–384.00 MHz U.S. Government .............................................................. 406.00–450.00 MHz 70-Centimeter Amateur ..................................................... 420.00–450.00 MHz Low Range ........................................................................ 450.00–470.00 MHz Public Service ................................................................... 806.00–823.98 MHz Conventional Systems ...................................................... 851.00–856.00 MHz Conventional/Trunked Systems ........................................ 856.00–861.00 MHz Trunked Systems .............................................................. 861.00–866.00 MHz Public Safety ..................................................................... 866.00–869.00 MHz High Range ....................................................................... 894.01–902.00 MHz 33-Centimeter Amateur ..................................................... 902.00–928.00 MHz Private Trunked ................................................................. 935.00–940.00 MHz General Trunked ............................................................... 940.00–941.00 MHz Fixed Services................................................................... 941.00–944.00 MHz Studio-to-Transmitter Broadcast Links .............................. 944.00–952.00 MHz Private Fixed Services, Paging ......................................... 952.00–960.00 MHz Aeronautical Navigation .................................................. 960.00–1000.00 MHz 34 20-418.fm Page 35 Wednesday, August 4, 1999 12:42 PM Primary Usage As a general rule, most radio activity is concentrated on the following frequencies: VHF Band Activities Frequencies (MHz) Government, Police, and Fire Emergency Services 153.785–155.980 158.730–159.460 Railroad 160.000–161.900 UHF Band Activities Frequencies (MHz) Land-Mobile Paired Frequencies 450.000–470.000 Base Stations 451.025–454.950 Mobile Units 456.025–459.950 Relay Repeater Units 460.025–464.975 Remote Control Stations 465.025–469.975 Note: Remote control stations and mobile units operate at 5 MHz higher than their associated base stations and relay repeater units.

AIR FREQUENCY CONVERSION The tuning location of a station can beexpressed in frequency (kHz or MHz) 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 by 1,000. 30.62 MHz x 1000=30620 kHz To convert from kHz to MHz, divide by 1,000. 127, 800 kHz =127.8 MHz ----------------------1000 To convert MHz to meters, divide 300 by the number of megahertz. 300 = 1.75 meters ---------171 MHz 39 20-418.fm Page 40 Wednesday, August 4, 1999 12:42 PM TROUBLESHOOTING If you have problems, here are some suggestions that might help. If none of these suggestions help, take your PROBLEM Scanner is totally inoperative. Scanner is on but will not scan. scanner to your local RadioShack store for assistance. POSSIBLE CAUSE No power. REMEDY Make sure you plugged the scanner into a working AC or DC outlet. • SQUELCH is not correctly adjusted. • Adjust SQUELCH clockwise. • A channel has been manually selected. • Press SCAN. While scanning, the scanner locks on frequencies that have an unclear transmission. “Birdies.” Avoid programming frequencies 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. 40 20-418.fm Page 41 Wednesday, August 4, 1999 12:42 PM CARE AND MAINTENANCE Your PRO-2045 200-Channel Direct Entry Programmable Scanner is an example of superior design and craftsmanship. The following suggestions will help you care for the PRO-2045 so you can enjoy it for years. CLEANER Keep the scanner dry. If it gets wet, wipe it dry immediately. Liquids can contain minerals that can corrode the electronic circuits. 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 your scanner’s internal components can cause a malfunction and might invalidate the scanner’s warranty and void your FCC authorization to operate it. If your scanner is not operating as it should, take it to your local RadioShack store for assistance. Use and store the scanner only in normal temperature environments. 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 premature wear of parts. 41 20-418.fm Page 42 Wednesday, August 4, 1999 12:42 PM SPECIFICATIONS Frequency Coverage, Step, and Default Modulation Modes: Range (MHz) Step (kHz) Mode 29–54 5 NFM 108–136.975 12.5 AM 137–174 5 NFM 216–224.9875 12.5 NFM 225–399.9875 12.5 AM 400–512 12.5 NFM 806–823.9375 12.5 NFM 851–868.9375 12.5 NFM 896.1125–1,000 12.5 NFM Channels . . . . . . . . . . . . . 210 (20 Channels × 10 Banks + 10 Monitor Memories) Sensitivity (20 dB S/N with 60% modulation for AM; 3 kHz deviation for NFM): NFM S+N/N=20 dB AM S+N/N=20 dB 40.84 MHz 162.4 MHz 453.25 MHz 954.9125 MHz . . . . ....... ....... ....... ....... ...... ...... ...... ...... ...... ...... ...... ...... 0.5 µV 0.6 µV 0.6 µV 0.8 µV 127.175 MHz . . . . . . . . . . . . . . . . . . . . 1.5 µV 230.05 MHz . . . . . . . . . . . . . . . . . . . . 1.5 µV 325.05 MHz . . . . . . . . . . . . . . . . . . . . 1.5 µV Direct/Limit Search Speed: Normal Speed . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 100 Steps/Second Hypersearch . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 300 Steps/Second Scanning Speed . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 50 Channels/Second Priority Channel Sampling Interval . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2 Seconds Programmable Delay . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2 Seconds 42 20-418.fm Page 43 Wednesday, August 4, 1999 12:42 PM IF Frequencies . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1st IF: 370.7 MHz 2nd IF: 10.85 MHz 3rd IF: 450 kHz (NFM) Audio Power . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1 Watt Maximum Built-In Speaker . . . . . . . . . . . . . . . . . . 27/16-Inch (57 mm), 8-Ohm, Dynamic Type Maximum Current Drain . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 500 mA Power Requirement . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 12 Volts AC Adapter . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
