Operation; Turning On The Power; Setting The Squelch Level - Uniden UH6000 Owner's Manual

Operation

Turning on the Power

Press and hold the Power/Channel Selector.
Low-Voltage/High-Voltage Alert
If the power supply voltage exceeds 18VDC, an alert tone
sounds and dc HI flashes for 5 seconds. The power source
must not exceed 25VDC otherwise permanent damage
may occur to your radio, which may not be covered by the
manufacturer's warranty.
NOTE
If the input voltage falls below 10VDC, dc Lo flashes for 5
seconds. The power turns off automatically if voltage falls
below 8.5VDC.
Switch your UH6000 OFF and disconnect it from the power
source, before locating the cause of the power supply problem.

Setting the Squelch Level

The Squelch circuit determines when the radio's audio output (speaker)
turns on, based on the strength of received signals. This avoids noise
and undesired signals constantly coming through the speakers.
Press the Power/Channel Selector momentarily. SqL shows and the
current squelch level will flash.
Turn the Channel Selector to select the desired squelch level.
