Care and Maintenance
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, unless you have turned 2:OFF the
3:KEY BEEP in the menu system.
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, may provide better reception.
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. 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
may be receiving a birdie. Birdies are internally generated
signals inherent in the electronics of the receiver.
Press L/O to lockout the channel, and then press RSM
to resume scanning.
• Narrow band responses (start scanning without reason)
occur in the VHF low band in case of strong signals around
89.3, 99.6, 102.6, and 127.7 MHz.
