CONNECTING AN EARPHONE/ HEADPHONES/ EXTERNAL SPEAKER

The 1/8-inch EXT SP jack on the back of the scanner lets you connect an optional earphone (such as Cat. No. 33-175), headphones (such as Cat. No. 20-210), or an external speaker (such as Cat. No. 21-549).

Note: Connecting any external de- vice to the EXT SP jack automatically disconnects the internal speaker.

Listening Safely

To protect your hearing, follow these guidelines when you use an ear- phone or headphones.

•Do not listen at extremely high volume levels. Extended high- volume listening can lead to per- manent hearing loss.

•Set the volume to the lowest set- ting before you begin listening. After you begin listening, adjust the volume to a comfortable level.

•Once you set the volume, do not increase it. Over time, your ears adapt to the volume level, so a volume level that does not cause discomfort might still damage your hearing.

Traffic Safety

Do not wear an earphone or head- phones while operating a motor vehi- cle or riding a bicycle. This can create a traffic hazard and could be illegal in some areas.

Even though some earphones and headphones let you hear some out- side sounds when listening at normal volume levels, they still can present a traffic hazard.
