Listening Safely
To protect your hearing, follow these
guidelines when you use the ear-
phone.
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 an earphone while operat-
ing a motor vehicle or riding a bicycle.
This can create a traffic hazard and
can be illegal in some areas.
Even though some earphones let you
hear some outside sounds when lis-
tening at normal volume levels, they
still can present a traffic hazard.
