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.

• 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.

For listening privately, you can connect
a pair of stereo headphones (not sup-
plied) with a

/

-inch (3.5-mm) plug into

the 

 jack. Your local Ra-

dioShack store carries a wide selection
of stereo headphones.

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

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.
