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 vol-
ume levels. Extended high-volume
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 vol-
ume level that does not cause dis-
comfort might still damage your
hearing.
TraffIc Safety
Do not wear headphones while operat-
ing a motor vehicle or riding a bicycle.
This can create a traffic hazard and
could be illegal in some areas.
Even though some headphones let you
hear some outside sounds when listen-
ing at normal volume levels, they still
can present a traffic hazard.
