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.
