AVOID POTENTIAL HEARING LOSS
• 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.
