Samsung Dart SGH-T499 User Manual page 170

Set the volume in a quiet environment and select the
•
lowest volume at which you can hear adequately.
Be aware that you can adapt to higher volume settings
•
over time, not realizing that the higher volume may be
harmful to your hearing.
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.
