USING HEADPHONES
For private listening, you need a pair of
headphones (not supplied) with a
1 /
8
-
inch (3.5 mm) plug. Your local Ra-
dioShack store has a wide selection of
headphones.
Plug the headphones into the EAR-
PHONE jack on the back of the clock
radio.
Note: When you connect head-
phones, the internal speaker is auto-
matically disconnected.
LISTENING SAFELY
To protect your hearing, follow these
guidelines when you use headphones.
• Set the volume to the lowest set-
ting before you begin listening.
After you begin listening, adjust
the volume to a comfortable level.
• Do not listen at extremely high
volume levels. Extended high vol-
ume listening can lead to perma-
nent hearing loss.
• Once you set the volume, do not
increase it. Over time, your ears
adapt to the volume level, so a
volume level that does not cause
discomfort might still damage your
hearing.
