First, turn off the scanner and your vehicle's ignition. Make sure you replace the fuse only
with another fuse of the same type and rating (2-amp, fast-acting glass fuse).
service and repair
If your scanner is not performing as it should, take it to your local RadioShack store for
assistance. To locate your nearest RadioShack, use the store locator feature on
RadioShack's website (www.radioshack.com), or call 1-800-The Shack (800-843-7422) and
follow the menu options. Modifying or tampering with the scanner's internal components
can cause a malfunction and might invalidate its warranty and void your FCC
authorization to operate it.
birdie frequencies
Every scanner has birdie frequencies. Birdies are signals created inside the scanner's
receiver. These operating frequencies might interfere with transmissions 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 SQ clockwise to omit the birdie.
To find the birdies in your scanner, begin 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. This is a birdie. Make a list of all the birdies in your scanner for future
reference.
