Safety Guidelines
select the lowest volume at which you can
hear adequately.
]
When using headphones, turn the
volume down if you cannot hear the
people speaking near you or if the person
sitting next to you can hear what you are
listening to.
]
Do not turn the volume up to block
out noisy surroundings. If you choose
to listen to your portable device in a
noisy environment, use noisecancelling
headphones to block out background
environmental noise.
]
Limit the amount of time you listen. As the
volume increases, less time is required
before your hearing could be affected.
]
Avoid using headphones after exposure
to extremely loud noises, such as rock
concerts, that might cause temporary
hearing loss. Temporary hearing loss might
cause unsafe volumes to sound normal.
]
Do not listen at any volume that causes
you discomfort. If you experience ringing
in your ears, hear muffled speech or
experience any temporary hearing difficulty
after listening to your portable audio
device, discontinue use and consult your
doctor.
