Health and Safety Information 39
• 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-cancelling
headphones to block out background
environmental noise. By blocking
background environment noise, noise
cancelling headphones should allow you to
hear the music at lower volumes than
when using earbuds.
• Limit the amount of time you listen. As the
volume increases, less time is required
before you 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.
