Safety
sound and distorted hearing. Individual susceptibility to noise-
induced hearing loss and other potential hearing problems varies.
The amount of sound produced by a portable audio device varies
depending on the nature of the sound, the device, the device
settings and the headphones. You should follow some common
sense recommendations 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-cancelling 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.
