45 AVOIDING IMAGE FREQUENCIES You might discover one of your regular stations on anoth- er frequency that is not listed. This might be what is known as an image frequency. For example, you might find a ser- vice that regularly uses a frequency of 453.275 also on 474.675. To see if it is an image, do a little math. Note the new frequency. 474.675 Double the intermediate frequency of 10.7 MHz (21.400) and subtract it from the new frequency. –21.400 If the answer is the regular frequency, 453.275 then you have tuned to an image. Occasionally you might get interference on a weak or dis- tant channel from a strong broadcast 21.4 MHz below the tuned frequency. This is rare, and the image signal is usu- ally cleared whenever there is a broadcast on the actual frequency. 20-310.fm Page 45 Wednesday, August 4, 1999 10:49 AM
46 FREQUENCY CONVERSION The tuning location of a station can be expressed in fre- quency (kHz or MHz) or in wavelength (meters). 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 MHz by 1,000: 30.62 MHz ´ 1000 = 30,620 kHz To convert from kHz to MHz, divide the number of kHz by 1,000. 127,800 kHz ¸ 1000 = 127.8 MHz To convert MHz to meters, divide 300 by the number of MHz. 300 ¸ 50 MHz = 6 meters 20-310.fm Page 46 Wednesday, August 4, 1999 10:49 AM
47 TROUBLESHOOTING If your scanner is not working as it should, these sugges- tions might help you eliminate the problem. If the scanner still does not operate properly, take it to your local Ra- dioShack store for assistance. PROBLEMPOSSIBLE CAUSESREMEDIES Scanner is totally inop- erative.The batteries are dead.Replace the batter- ies with fresh ones or recharge the bat- tery pack. The optional AC or DC power adapter is not con- nected.Be sure the adapter is fully inserted into the PWR/DC 9V jack. Poor or no receptionImproperly connected antenna.Be sure the antenna is properly connected. Programmed frequencies are the same as birdie frequen- cies.Avoid program- ming frequencies listed under “Birdie Frequencies” on Page 37 or only select them manu- ally. Error appears on the display.Programming error.Reprogram the fre- quency correctly. Keypad does not work.Keylock is turned on.Turn off keylock. 20-310.fm Page 47 Wednesday, August 4, 1999 10:49 AM
48 Keys do not work or dis- play changes.Undetermined error.Turn the scanner off then on again, or reset the scan- ner (see “Reset- ting/Initializing the Scanner” on Page 49). Scanner is on but will not scan. SQUELCH is not correctly adjusted.Adjust SQUELCH clockwise (see “Turning On the Scanner and Set- ting SQUELCH” on Page 21). In the scan mode, the scanner locks on fre- quencies that have an unclear transmis- sion.Birdies. Avoid program- ming frequencies listed under “Birdie Frequencies” on Page 37 or only lis- ten to them manu- ally. PROBLEMPOSSIBLE CAUSESREMEDIES 20-310.fm Page 48 Wednesday, August 4, 1999 10:49 AM
49 RESETTING/INITIALIZING THE SCANNER If the scanner’s display locks up or does not work properly after you connect a power source, you might need to reset or initialize the scanner. IMPORTANT! If you have problems, first try to reset the scanner (see “Resetting the Scanner”). If that does not work, you can initialize the scanner (see “Initializing the Scanner” on Page 50); however, this clears all information stored in your scanner’s 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 (as shown below) and gently press then release the reset button inside the opening. Note: If the scanner still does not work properly, you might need to initialize the scanner (see “Initializing the Scan- ner” on Page 50). 20-310.fm Page 49 Wednesday, August 4, 1999 10:49 AM
50 Initializing the Scanner Caution: This procedure clears all information you stored in the scanner’s memory. Initialize the scanner only when you are sure the scanner is not working properly. 1. Turn off the scanner, then turn it on again. 2. Press and hold CLEAR. 3. While holding down CLEAR, insert a pointed object, such as a straightened paper clip, into the reset opening on the side of the scanner and gently press then release the reset button inside the opening. 4. When the display reappears, release CLEAR. Note: You must release RESET before releasing CLEAR, otherwise the memory might not clear. 20-310.fm Page 50 Wednesday, August 4, 1999 10:49 AM
