Note: If the CD-3321 does not operate when you turn it on, remove the DC adapter from your vehicle’s cigarette- lighter socket and check the socket for debris. Also check the fuse in the adapt- er and your vehicle’s fuse block.

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

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

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

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