AE55H OWNER’S MANUAL 11 GENERAL GUIDE TO SCANNING BIRDIE FREQUENCIES Every scanner has birdie frequencies. Birdies are signals created inside the scanner’s receiver. These operating frequencies might interfere with broadcasts on the same frequencies. If you program one of these frequencies, you hear only noise on that frequency. If the interference is not severe, you might be able to turn SQUELCH clockwise to cut out the birdie. To find the birdies in your scanner, being by disconnecting the antenna and moving 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 frequency 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. SPECIFIED INTERVALS Frequencies in different bands are accessible only at specific intervals. For example: Frequency RangesSpecified Interval 26-54, 68-88, 137-144 and 146-174 MHz5.0 kHz steps 144-146 and 380-512 MHz12.5 kHz steps TROUBLESHOOTING If your scanner is not working as it should, these suggestions might help you eliminate the problem. If the scanner still does not operate properly, take it to your local store for assistance.

AE55H OWNER’S MANUAL 12 RESETITNG/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 it. Important: If you have problems, first try to reset the scanner. If that does not work, you can initialize the scanner, however, initializing clears all frequencies you stored in the scanner’s memory and initialilzes the scanner to its default settings. 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 hole on the side of the scanner. Then gently press and release the reset button inside the opening. The display goes blank, then information reappears. Initializing the Scanner Important: This procedure clears all frequencies you stored in the scanner’s memory and initializes the scanner to its default settings. 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. While holding down CLEAR, insert a pointed object, such as a straightened paper clip, into the reset hole on the side of the scanner. Then gently press and release the reset button inside the opening. The display goes blank, then information reappears. Note: You must release the reset button before you release CLEAR. Otherwise, the memory might not clear. 3. When the display reappears, release CLEAR. CARE AND MAINTENANCE 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. Use only fresh batteries of the required size and 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 solvents, or strong detergents to clean the scanner.
