USING HEADPHONES

For private listening, plug a pair of op- tional headphones (not supplied) with a 1/8-inch (3.5-mm) plug into the jack. Your local RadioShack store has a wide selection of headphones.

Listening Safely

To protect your hearing, follow these guidelines when you use headphones.

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

•Do not listen at extremely high volume levels. Extended high-vol- ume listening can lead to perma- nent hearing loss.

•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.
