Listening Safely
To protect your hearing, follow these guidelines when
you use an earphone.
• Do not listen at extremely high volume levels.
Extended high-volume listening can lead to perma-
nent hearing loss.
• Set the volume to its lowest level before you begin
listening. After you put on the earphone, adjust the
volume to a comfortable listening level.
• Do not increase the volume once you have estab-
lished a comfortable listening level. Over time, your
ears adapt to the volume level, so a volume level that
does not cause discomfort might still damage your
hearing.
Traffic Safety
Do not wear an earphone while operating a motor vehicle
or riding a bicycle. This can cause a traffic hazard and
could be illegal in some areas.
Even though some earphones let you hear outside
sounds when listening at normal volume levels, they still
can present a traffic hazard.
