Avoid Potential Hearing Loss - UTStarcom CDM8960 Manual Del Usuario

SAFETY AND WARRANTY
Prolonged exposure to loud sounds (including music) is the most
common cause of preventable hearing loss. Some scientific research
suggests that using portable audio devices, such as portable music
players and cellular telephones, at high volume settings for long
durations may lead to
permanent noise-induced hearing loss. This includes the use of
headphones (including headsets, earbuds and Bluetooth ® or other
wireless devices). Exposure to very loud sound has also been associat-
ed in some studies with tinnitus (a ringing in the ear), hypersensitiv-
ity to 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 set-
tings and the headphones. You should follow some commonsense
recommendations when using any portable audio device:
• Set the volume in a quiet environment and select the lowest vol-
ume 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 environ-
mental 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.
