Precautions
Before you use this scanner, please read and observe
the following.
EARPHONE WARNING!
Be sure to use only a monaural earphone with this
scanner. You can also use an optional 32 Ω stereo
headset. Use of an incorrect earphone or stereo
headset might be potentially hazardous to your
hearing. The output of the phone jack is monaural, but
you will hear it in both headphones of a stereo
headset.
Set the volume to a comfortable audio level coming
from the speaker before plugging in the monaural
earphone or a stereo headset of the proper
impedance (32 Ω). Otherwise, you might experience
some discomfort or possible hearing damage if the
volume suddenly becomes too loud because of the
volume control or squelch control setting. This might
be particularly true of the type of earphone that is
placed in the ear canal.
WARNING!
Uniden does not represent this unit to be
waterproof. To reduce the risk of fire or electrical
shock, do not expose this unit to rain or moisture.
