-inch plug (not

supplied) into the system’s 

jack. This mutes the system’s speak-
ers. Your local RadioShack store sells
a wide selection of headphones.

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.

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.
