partment.

USING HEADPHONES
To listen to the system without disturb-
ing others, plug a pair of stereo head-
phones with a
1 /
8
-inch plug (not
supplied) into the system’s PHONES
jack. This mutes the system’s speak-
ers. Your local RadioShack store sells
a wide selection of headphones.
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 put on the headphones,
adjust the volume to a comfortable
level.
• Do not listen at extremely high
volume levels. Extended high-
volume listening can lead to per-
manent hearing loss.
• Once you set the volume, do not
increase it. Over time, your ears
adapt to the volume level, so a
level that does not cause discom-
fort might still damage your hear-
ing.
Traffic Safety
Do not wear headphones while oper-
ating a motor vehicle or riding a bicy-
cle. This can create a traffic hazard
and is illegal in some areas.
Even though some headphones are
designed to let you hear some outside
sounds when listening at normal vol-
ume levels, they still present a traffic
hazard.
