2.Put eight D batteries in the battery compartment as indicated by the polarity symbols (+ and –) marked inside.

3. Replace the cover and snap it shut.

When the sound weakens or the CD- 3327 stops operating properly, replace all eight batteries.

Cautions:

•Always remove old or weak batter- ies. Batteries can leak chemicals that can destroy electronic parts.

•If you do not plan to use the CD- 3327 with batteries for several weeks, or if you plan to power the CD-3327 using only AC power, remove the batteries.

USING HEADPHONES

For private listening, plug a pair of op- tional stereo headphones with a 1/8-inch

(3.5-mm) plug into the PHONES 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 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.
