32 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: 30.62 (MHz) ¥ 1000 = 30,620 kHz To convert from kHz to MHz, divide the number of kilohertz by 1,000: 127,800 (kHz) ¸ 1000 = 127.8 MHz To convert MHz to meters, divide 300 by the number of megahertz: 300 ¸ 50 MHz = 6 meters 20-147.fm Page 32 Tuesday, August 3, 1999 3:23 PM
33 TROUBLESHOOTING If your scanner is not working as it should, these suggestions might help you elimi- nate the problem. If the scanner still does not operate properly, take it to your local RadioShack store for assistance. Problem Possible Causes Remedies The scanner does not work at all.The AC adapter is not properly connected.Be sure the AC adapter is plugged into a working AC outlet. The DC power cord or DC cigarette-lighter power cord is not con- nected.Be sure the power cord is ful- ly inserted into the DC 13.8V jack. Be sure the power cord’s red wire is connected correctly to a voltage source and the black wire is connected cor- rectly to ground. Poor or no reception. Improperly connected antenna.Be sure the antenna is prop- erly connected. Scanner is on but does not scan. SQ is not correctly ad- justed.Adjust SQ counterclockwise (see “Turning On the Scan- ner/Setting Volume and Squelch” on Page 19). In the scan mode, the scanner locks on fre- quencies that have an unclear transmission.Birdies. Avoid programming frequen- cies listed under “Birdie Fre- quencies” on Page 25 or only listen to them manually. 20-147.fm Page 33 Tuesday, August 3, 1999 3:23 PM
34 CARE AND MAINTENANCE Your RadioShack PRO-2056 50-Channel Home/Mobile 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. Liquids might contain minerals that can corrode the electronic circuits. Keep the scanner away from dust and dirt, which can cause prema- ture wear of parts. Handle the scanner gently and carefully. Dropping it can damage cir- cuit 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 deter- gents 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 authoriza- tion to operate it. If your scanner is not performing as it should, take it to your local RadioShack store for assistance. 20-147.fm Page 34 Tuesday, August 3, 1999 3:23 PM
35 REPLACING THE FUSES The fuses in the scanner’s DC power cord and DC cigarette-lighter power cord help protect your scanner from power surges and short circuits. If the fuse in the DC power cord has blown, replace it with a 1-amp, fast-acting glass fuse (such as RadioShack Cat. No. 270-1005). For the fuse in the DC cigarette-lighter power cord, replace it with a 2-amp, fast-acting glass fuse (such as RadioShack Cat. No. 270- 1007). Warnings: • Before you begin, turn off the scanner and your vehicle’s igni- tion. • Make sure you replace the fuse only with another fuse of the same type and rating. Replacing the Fuse in the DC Power Cord 1. Turn off the scanner and your vehicle’s ignition. 2. To open the fuse holder, push the fuse holder ends together, then turn either end counterclockwise and release it.3. If the fuse is blown, replace it. 4. To close the fuse holder, push the fuse holder ends together, then turn either end clockwise. Replacing the Fuse in the DC Cigarette-Lighter Power Cord 1. Turn off the scanner and your vehicle’s ignition. 2. To open the cigarette-lighter plug, turn the cap counterclockwise and remove it. 3. If the fuse is blown, replace it. 4. Replace the cap.(add corrected illus F26, deleting curved arrow) 20-147.fm Page 35 Tuesday, August 3, 1999 3:23 PM
