Troubleshooting
The scanner is not working at all.
• The AC or DC adapter might not be connected. Be sure the adapter's barrel
plug is fully inserted into the DC 9V jack. The center tip of the adapter's
barrel plug must be set to positive.
The scanner does not receive any stations or reception is poor.
• An antenna is not connected or is connected incorrectly. Be sure an antenna
is properly connected to the scanner.
• Reception may be blocked by walls or other obstructions. Try moving to a
different area.
The scanner is on but does not scan.
• The squelch might not be adjusted correctly. Turn SQUELCH clockwise.
• Only one channel or no channels are stored. Store frequencies into more
than one channel.
The keypad does not work.
• The scanner might need to be reset or initialized. Turn the scanner off then
on again, or initialize the scanner (see "Initializing the Scanner" on page 26).
While scanning, the scanner locks on frequencies that have an unclear
transmission.
• Some frequencies programmed into the scanner might be the same as
birdie frequencies. Avoid programming birdie frequencies or only listen to
them manually.
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:
1. 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.
2. Use the Tune to 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.
