31 The birdie frequencies on this unit to watch for are: To find the birdies in your scanner, begin by disconnecting the antenna and mov- ing it away from the scanner. Make sure that no other nearby radio or TV sets are turned on near the scanner. Use the search function and scan every frequen- cy 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. GUIDE TO THE ACTION BANDS United States Broadcast Bands In the United States, there are several broadcast bands. The standard AM and FM bands are probably the most well known.

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 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 20-417.fm Page 39 Wednesday, August 4, 1999 11:33 AM
40 TROUBLESHOOTING If you have problems, here are some suggestions that might help. If they do not, take your scanner to your local RadioShack store for assistance. PROBLEM POSSIBLE CAUSE REMEDY Scanner is on but will not scan.SQUELCH is not correctly adjusted.Adjust SQUELCH clockwise. Only one channel or no channels are stored.Store frequencies into more than one channel. The scanner’s display must be reset.Reset the scanner’s display (see “Resettin g the Scan- ner’s Display” on Pa ge 10). Scanner is totally inopera- tive.No power. Make sure the scanner is plu gged into a working AC or DC outlet. The AC or DC adapter is not connected.Be sure the adapter’s barrel plu g is fully plugged into the DC 12V jack. The scanner’s display dims.The AC or DC adapter is not providin g the required volta ge.Make sure the AC or DC adapter is set to provide the required voltage. Keypad does not work or display randomly chan ges.The scanner’s display must be reset.Reset the scanner’s display (see “Resettin g the Scan- ner’s Display” on Pa ge 10). Poor or no reception. An antenna is not con- nected or connected incorrectly.Make sure an antenna is correctly connected to the scanner. Pro grammed frequencies are the same as “birdie” frequencies.Avoid programming fre- quencies listed under “Birdie Frequencies” on Pa ge 30, or only listen to them manually. Error appears. Programming error. Reprogram the frequency correctly, includin g the deci- mal point. While scannin g In the scan mode, the scanner locks on frequencies that have an unclear transmis- sion.Programmed frequencies are the same as “birdie” frequencies.Avoid programming fre- quencies listed under “Birdie Frequencies” on Pa ge 30, or only listen to them manually. 20-417.fm Page 40 Wednesday, August 4, 1999 11:33 AM
