The Basics
listening safely
To protect your hearing, follow these guidelines when
you use headphones.
•
Adjust
VOL
(volume) to its lowest level before
putting on headphones. With the headphones on,
adjust
VOL
to a comfortable level.
•
Avoid increasing the volume once you set it. Over
time, your sensitivity to volume decreases, so
volume levels that do not cause discomfort might
damage your hearing.
•
Avoid listening at high volume levels. Prolonged
exposure to high volume levels can cause
permanent hearing loss.
traffi c safety
Do not wear headphones while driving. This can create
a traffi c hazard and is illegal in some areas. Even
though some headphones let you hear outside sounds
when you listen at normal levels, they still can present
a traffi c hazard.
