Care and Maintenance
General Use
Turn the scanner off before disconnecting the power.
If memory is lost, simply reprogram each channel.
Always press each button firmly until you hear the entry tone for that
key entry.
Location
Do not use the scanner in high-moisture environments such as the
kitchen or bathroom.
Avoid placing the unit in direct sunlight or near heating elements or
vents.
If the scanner receives strong interference or electrical noise, move it
or its antenna away from the source of the noise. If possible, a higher
elevation might provide better reception.
Also try changing the height or angle of the antenna.
Cleaning
Disconnect the power to the unit before cleaning.
Clean the outside of the scanner with a mild detergent.
To prevent scratches, do not use abrasive cleaners or solvents. Be
careful not to rub the LCD window.
Do not use excessive amounts of water.
Repairs
Do not attempt any repair. The scanner contains no user serviceable
parts. Contact the Uniden Customer Service Center or take it to a
qualified repair technician.
Birdies
All radios can receive “birdies” (undesired signals). If your scanner stops
during Scan mode and no sound is heard, it might be receiving a birdie.
Birdies are internally generated signals inherent in the electronics of the
scanner. Press
L/O
to lock out the channel.

holding down

contents are erased .
