safety of individuals or protection of property. Use Channel 9 to render

Maintenance

Every six to twelve months, check to make sure that:
► The Voltage Standing Wave Ratio (VSWR) is less than 2:1.
► All electrical connections are secure and free of corrosion.
► The antenna cable shows no wear or damage.
► All mounting screws are securely fastened.
► Inspect all screws and other mounting hardware.
If your radio is not performing to your expectations, please try these simple
steps. If these steps don't solve your problem, visit www.uniden.com for

Problem:
Radio won't turn
on (no power)
Poor reception
– Turn the knob clockwise to boost the reception of weak
signals, or counter-clockwise to reduce the reception of
strong signals.
– In areas where strong signals cause noise and distortion,
reduce the RF gain (turn the knob counterclockwise).
– In areas where weaker signals are difficult to hear,
– increase the RF gain (turn the knob clockwise).
– Move the CH9 switch up; the radio automatically tunes to
channel 9 and disables the channel selector.
– Move the switch back down to return to the previous
channel and enable the channel selector.
