When using any portable audio device:
• Set the volume in a quiet environment and
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 noise-canceling
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 diffi culty after listening to
your portable audio device, discontinue use
and consult your doctor.
