APPENDIX
x 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.
x Limit the amount of time you listen. As the volume increases, less time is required before your
hearing could be affected.
x Avoid using headphones after exposure to extremely loud noises, such as concerts, that might
cause temporary hearing loss. Temporary hearing loss might cause unsafe volumes to sound
normal.
x 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.
