Health and Safety Information 165
• 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. 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.
