41 Chan- nel No.Frequency Chan- nel No.Frequency Ship Shore Ship Shore Birdie Frequencies Every scanner has birdie frequencies. Birdies are signals created in- side the scanner’s receiver. These operating frequencies might inter- fere with broadcasts on the same frequencies. If you program one of these frequencies, you hear only noise on that frequency. If the inter- ference is not severe, you might be able to turn SQUELCH clockwise to cut out the birdie. The birdie frequencies (in MHz) found in this scanner are: 19 156.9500 156.9500 79 156.9750 156.9750 20 157.0000 161.6000 80 157.0250 157.0250 21 157.0500 157.0500 81 157.0750 157.0750 22 157.1000 157.1000 82 157.1250 157.1250 23 157.1500 157.1500 83 157.1750 157.1750 24 157.2000 161.8000 84 157.2250 161.8250 25 157.2500 161.8500 85 157.2750 161.8750 26 157.3000 161.9000 86 157.3250 161.9250 27 157.3500 161.9500 87 157.3750 161.9750 28 157.4000 162.0000 88 157.4250 157.4250 31.2000 41.6000 52.6000 116.0375 171.2500 410.0000 430.0000 480.4750 489.1875 489.2500 489.3500 489.4500 489.5000 813.4000 814.0000 932.6000 932.8250 938.3750 940.9000 Chan- nel No.Frequency Chan- nel No.Frequency Ship Shore Ship Shore 20-513.fm Page 41 Wednesday, August 4, 1999 2:39 PM
42 To find the birdies in your particular scanner, begin by disconnecting the antenna and moving it away from the scanner. Make sure that no other nearby radios or TVs are turned on near the scanner. Use the search function to search every frequency range from its lowest to the highest frequency. Occasionally, the searching will stop as if it had found a sig- nal, often without any sound. That is a birdie. Make a list of all the birdies in your scanner for future reference.

43 Primary Usage As a general rule, most of the radio activity is concentrated on the fol- lowing frequencies: VHF Band UHF Band Note: Remote control stations and mobile units operate at 5 MHz high- er than their associated base stations and relay repeater units. BAND ALLOCATION To help decide which frequency ranges to scan, use the following list- ing of the typical services that use the frequencies your scanner re- ceives. These frequencies are subject to change, and might vary from area to area. For a more complete listing, refer to the book “Beyond Police Call,” available at your local RadioShack store.

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 necessary conversions. 1 MHz (million) = 1,000 kHz (thousand) To convert MHz to kHz, multiply the number of megahertz by 1,000: 9.62 (MHz) x 1000 = 9620 kHz To convert from kHz to MHz, divide the number of kilohertz 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 20-513.fm Page 47 Wednesday, August 4, 1999 2:39 PM
48 TROUBLESHOOTING If you have problems, here are some suggestions that might help. If none do, take your scanner to your local RadioShack store for as- sistance. PROBLEM POSSIBLE CAUSE REMEDY Keys do not work or display changes at random.Undetermined error. Reset the scanner (see “Resetting the Scanner” on Page 49). Scanner is on but will not scan.SQUELCH is not correctly adjusted.Adjust SQUELCH clock- wise. Only one channel or no channels are stored.Store frequencies into more than one channel. Scanner is totally inoperative.No power. Check the batteries or make sure the scanner is plugged into a working AC or DC outlet. Be sure the adapter’s barrel plug is fully plugged into the POWER jack. Recharge the recharge- able batteries or replace the non-rechargeable batteries. The scanner’s dis- play dims or the scanner sounds a tone every 15 –30 seconds.Batteries are not correctly installed.Make sure the batteries are installed with the proper polarity (+ to + and – to –). Batteries are low. Recharge the recharge- able batteries or replace the non-rechargeable batteries. Keypad does not work.The keylock func- tion is activated.To turn off the keylock, press KEYLOCK until K/L disappears. 20-513.fm Page 48 Wednesday, August 4, 1999 2:39 PM
49 BATT.Lo appears.The batteries are weak.Recharge rechargeable batteries, or replace non- rechargeable batteries. PROBLEM POSSIBLE CAUSE REMEDY RESETTING THE SCANNER If the scanner’s display locks up or does not work properly after you connect power, you might need to reset the scanner. Caution: This procedure clears all the information you have stored into the scanner (such as frequencies and car numbers). Before you reset the scanner, try turning it off and on to see if it begins working properly. Reset the scanner only when you are sure it is not working properly. 1. Turn off the scanner. 2. While you hold down the 2 and 9 keys, turn on the scanner. If you still have problems after resetting the scanner, take it to your lo- cal RadioShack store. Poor or no recep- tion.Batteries are weak or dead.Check the batteries, or make sure the scanner is plugged into a working AC or DC outlet. Error appears. Frequency entered incorrectly.Re-enter the frequency correctly, including the decimal point. While scanning, the scanner locks on frequencies that have an unclear transmission.Stored frequencies are the same as “birdie” frequencies.Avoid storing frequen- cies listed under “Birdie Frequencies” on Page 41, or only listen to them manually.

50 CARE AND MAINTENANCE Your RadioShack PRO-74 100-Channel VHF/UHF/Air/800 MHz Race Scanner is an example of superior design and craftsmanship. The fol- lowing suggestions will help you care for your scanner so you can en- joy it for years. Keep the scanner dry. If it gets wet, wipe it dry immedi- ately. Liquids can contain minerals that can corrode the electronic circuits. Use only batteries of the required size and recommended type. Always remove old and weak batteries. They can leak chemicals that destroy electronic circuits. Handle the scanner gently and carefully. Dropping it can damage circuit boards and cases and can cause the scanner to work improperly. Use and store the scanner only in normal temperature environments. Temperature extremes can shorten the life of electronic devices, damage batteries, and distort or melt plastic parts. Keep the scanner away from dust and dirt, which can cause premature wear of parts. Wipe the scanner with a damp cloth occasionally to keep it looking new. Do not use harsh chemicals, cleaning sol- vents, or strong detergents to clean the scanner. Modifying or tampering with your scanner’s internal components can cause a malfunction, 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. 20-513.fm Page 50 Wednesday, August 4, 1999 2:39 PM
