Uniden USC230 Precautions

Precautions

Before you use this scanner, please read and observe the

following.

EARPHONE WARNING!

Be sure to use the supplied 8Ω monaural headphone.

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.
