care
Keep the scanner dry; if it gets wet, wipe it dry immediately. Use and store the scanner only in
normal temperature environments. Handle the scanner carefully; do not drop it. Keep the scanner
away from dust and dirt, and wipe it with a damp cloth occasionally to keep it looking new.
replacing the fuse
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.
