    Troubleshooting
    Resetting the Scanner
    If the scanners display locks up or stops operating 
    properly, you might need to reset the scanner.
    Caution: This procedure clears all the information 
    you have stored in the scanner. Before you reset the 
    scanner, try turning it off and on to see if it begins 
    working properly. Reset the scanner only when you 
    are sure it is not working properly.
    1. Turn off the scanner.
    2. While holding down 2, 9, and Hold, turn on the 
    scanner. It takes about 3 seconds to initialize 
    and CLEAr appears. Weather

    Care and Maintenance
    Care and MaintenanceKeep 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.
    General Use
    • Turn the scanner off before disconnecting the 
    power. 
    • Always write down the programmed frequencies 
    in the event of memory loss. 
    • If memory is lost, simply reprogram each 
    channel. The display shows 000.0000 in all 
    channels when there has been a memory loss. 
    • 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.

    Care and Maintenance
    • 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 receiver. 
    Press L/O to lock out the channel, then press Scan 
    to resume scanning. 
    If you still cannot get satisfactory results while using 
    your scanner or if you want additional information, 
    please call or write the Uniden Parts and Service 
    Division. The address and phone number are listed 
    in the Warranty at the end of this manual. If you 
    would like immediate assistance, please call
    Customer Service at (800) 297-1023.
