The fol- lowing information can help you make the necessary conversions. 1 MHz (million) = 1,000 kHz (thousand) To convert MHz to kHz, multiply the number of mega- hertz by 1,000: 30.62 (MHz) x 1000 = 30,620 kHz To convert from kHz to MHz, divide the number of kilo- hertz 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 Frequency Range Service 935.0125–939.9875 MHz PTR Frequency Range Service 940.0125–940.9875 MHz GTR Frequency Range Service 1240.000–1300.000 MHz HAM
78 Troubleshooting ˆTroubleshooting If you have problems with your scanner, here are some suggestions that might help you eliminate the problem. If they do not, take your scanner to your local RadioShack store for assistance. Problem Possible Cause Remedy Scanner is on but will not scanSQUELCH is not adjusted correctlyTurn SQUELCH clockwise. See “Turning on the Scanner and Set- ting Squelch” on Page 24 Poor or no recep- tionAn antenna is not connected or is connected incor- rectlyMake sure an antenna is con- nected to the scanner Programmed fre- quencies are the same as birdie fre- quenciesAvoid program- ming birdies or only select them manually. See “Birdie Frequen- cies” on Page 65 In scan mode, the scanner locks on frequencies with an unclear trans- mission Stored frequen- cies are the same as birdie frequen- ciesAvoid program- ming birdies or only select them manually Scanner is totally inoperative. No powerBatteries have failed Recharge the rechargeable bat- teries or replace the standard bat- teries Batteries are installed improp- erlyInstall the batteries according to the polarity markings, see “Using Batter- ies” on Page 10
79Troubleshooting RESETTING/INITIALIZING THE SCANNER If the scanners display locks up or does not work prop- erly after you connect a power source, you might need to reset or initialize it. Important: If you have problems with the scanner, first try to reset it to retain all memory. If that does not work, you can initialize the scanner; however, initializing clears all information stored in the scanners memory. Resetting the Scanner 1. Turn off the scanner, then turn it on again. 2. Insert a pointed object, such as a straightened paper clip, into the reset opening on the side of the scanner. Then gently press and release the reset button inside the opening. Note: Pressing the reset button does not clear the scan- ners memory. Initializing the Scanner Important: This procedure clears all information you stored in the scanners memory. Initialize the scanner Scanner is totally inoperative. No powerThe AC or DC adapter is not con- nected properlyBe sure the adapter’s barrel plug is properly connected to the PWR DC 9V jack Keypad does not workKeylock is on Turn keylock off, see “Using the Keylock” on Page 48 Keys do not work or display changesUndetermined errorTurn scanner off then on again, or reset the scanner, see “Resetting/Ini- tializing the Scan- ner” Problem Possible Cause Remedy
80 Troubleshooting only when you are sure the scanner is not working prop- erly. 1. Turn off the scanner, then turn it on again. 3
