Care and Maintenance
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.
