Birdie Frequencies

Every scanner has birdie frequencies. Birdies are signals created inside
the scanner's receiver, which may 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 Squelch clockwise to omit the birdie.
To find the birdies in your scanner, disconnect the antenna and move
it away from the scanner. Make sure that no other nearby radio or TV
sets are turned on near the scanner. Search every frequency range
from its lowest frequency to the highest. Occasionally, the searching
will stop as if it has found a signal, often without any sound. This
is a birdie. Make a list of all the birdies in your scanner for future
reference.

Care

Your scanner is not waterproof. Do not expose it to rain, moisture,
or extremely high humidity. If the scanner 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.

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.
