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 f requen cies used by police and fire departments, amb u­lance and transportation services, am­ateur radio, as well as aircraft communications, Citizen’s Band, and commercial FM and t elevision 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.
The secret to your scan ner’s ability to scan so many frequencies is its cus­tom-designed microprocessor — a tiny, built-in computer.

Count Feature — lets you keep track of how many times your sc anner has stopped on a channel.
Search Skip — lets you select up to 50 frequencies for the scanner t o skip during a search, so you can avoid fre­quencies you have already discovered or that have a continuous transmis­sion.
Two-Second Scan Delay — delays scanning for 2 seconds before mov ing to another channel, so you can hear more replies.
Data Skip — skips data signal s (non­modulated signals such as preamble signals for pagers) during scan, limit search, and direct search.
Attenuat or — reduces the scanner’s sensitivity to help limit reception to strong, nearby transmitters.
Memory Backup — keeps stored channel frequencies in memory for up to 3 days during a power loss.
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.
Backlit Display — lets you easily see the indicators on the scanner’s dis­play, even at night.

FCC NOTICE
Your scanner might caus e radio or T V interference even when it is operat ing 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
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 lega l to listen to almost every t ransmission your scanner can receive. However, there are some transmissions you should never intentionally listen to. These include:
• Telephone conversations (either cellular, cordless, or other private means of telephone signal trans­mission)
• Pager transmissions
• Any scrambled or encrypted transmissions
According to the Electronic Communi­cations Privacy Act (ECPA), you are subject to fines and possible imprison­ment for intentionally listening to, us­ing, or divulging the contents of such a transmission unless you have the con­sent of a party to the conversation (un­less such activity is otherwise illegal). RadioShack encourages responsible, legal scanner use.
If you cannot eliminate the interfer­ence, the FCC requires that you stop using your scanner.

Optional Outdoor Antenna
The supplied anten na 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 st rong lo­cal signals. Follow these steps to in­stall the supplied antenna.
8
Warning: When installing or removing an outdoor antenna, follow all cautions and warnings included with the anten­na.
20-418 .fm Page 9 Wednesday, Au gust 4, 1999 12 :42 PM
Note: Always use 50-ohm coaxial ca­ble to connect an outdoor ant enna 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 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:
• 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).
ANT
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.
1. Turn off the scanner.
2. While you press and hold down and 9, turn on the scanner.

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 t one 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 area, your scanner might be triggered by a broadcast in one area , but no t be triggered if you place it somewhere else (even close by).
To test for actual reception, yo ur radio must receive a test or emergency alert broadcast. The National Weather Ser­vice (NWS) broadcasts a te st a lert 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.
fringe
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 Sta nd­by Mode” o n Page 25) duri ng 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:
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:
If you use your scanner’s
• 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.

Testing the Weather Alert
Follow these steps to test the weather alert — to hear how it sounds and e n­sure that the circuitry is working.
Note:
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.

Traffic Safety
Do not wear an earphone or head­phones while operating a mo tor 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 a t normal volume levels, they still c an 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:
• Make sure the scanner i s 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.

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).

UNDERSTANDING CHANNEL-STORAGE BANKS
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.
MONITOR MEMORIES
The scanner also has 10 monitor memories. You can use these mem o­ries 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.

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.
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.

PRIORITY
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.
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 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 transmissi on ends.

USING CTCSS
CTCSS is frequently used when two different services or groups use the same frequencies, but are relatively close together. Each group set s their transmitters to different CTCSS fre­quencies, and sets their receivers to only let them hear transmiss ions that include the correct CTCSS frequenc y.
This helps to avoid radio interferenc e 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 t his feature. “Installing an Optional CTCSS Tone Board” on Page 12.

A GENERAL GUIDE TO SCANNING
Reception of the frequencies covered by your scanner is mainly “line-of­sight.” 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 located several hundred or even thousands of m iles away. This is because of summer atmospheric con-

Birdie Frequencies
Birdies are frequencies your scanner uses when it operates. T hese 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 migh t wan t to watch for:
29.4900 114.6875 147.4550 405.6000
29.4950 117.9625 147.4600 416.0000

114.4000 144.1800
To find the birdies in any receiver, begin by disc onnecting the antenna and movi ng 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.

CARE AND MAINTENANCE
Your PRO-2045 200-Channel Direct Entry Programmable Scanner is an
CLEANER
example of superior design and crafts­manship. The following suggestions will help you care for the PRO-2045 so you can enjoy it for years.
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.
