2.Install the batteries in the compart- ment and on top of the attached rib- bon, as indicated by the polarity symbols (+ and –) marked on the lower left corner of the back of the CD-3330.

3. Replace the cover.

When the CD-3330’s sound weakens or distorts, replace the batteries.

Cautions:

•Dispose of old batteries promptly and properly. Do not burn or bury them.

•If you do not plan to use the CD- 3330 with batteries for a month or more, or if you plan to use only AC power, remove the batteries. Batter- ies can leak chemicals that can destroy electronic parts.

USING HEADPHONES

For listening privately, you can connect a pair of stereo headphones (not sup- plied) with a 1/8-inch (3.5-mm) plug into the PHONES jack. Your local Ra- dioShack store carries a wide selection of stereo headphones.

Note: Connecting headphones automat- ically disconnects the built-in speaker.

Listening Safely

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

•Set the volume to the lowest setting before you begin listening. After you begin listening, adjust the volume to a comfortable 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 volume level, so a vol- ume level that does not cause dis- comfort might still damage your hearing.
