Listening Safely

To protect your hearing, follow these
guidelines when you use headphones.

• Set the sound source’s 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
volume levels. Extended high­volume 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
volume level that d oes not cause
discomfort might still damage your
hearing.

Traffic Safety

Do not wear h eadphones while oper­ating a motor vehicle or riding a bicy­cle. This can create a traffic hazard
and could be illegal in some areas.

Even though some headphones are
designed to let you hear some out side
sounds when listening at normal vol­ume levels, they still can present a
traffic hazard.
