For Your Safety 173
The amount of sound produced by a portable audio device varies depending on
the nature of the sound, the device, the device settings and the headphones. You
should follow some common sense recommendations when using any portable
audio device:
• Set the volume in a quiet environment and select the lowest volume 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 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.
TIA Safety Information
The following is the complete TIA Safety Information for wireless handheld devices.
Exposure to Radio Frequency Signal
Your wireless handheld portable device is a low power radio transmitter and
receiver. When ON, it receives and sends out Radio Frequency (RF) signals.
In August, 1996, the Federal Communications Commissions (FCC) adopted
RF exposure guidelines with safety levels for handheld wireless devices. Those
guidelines are consistent with the safety standards previously set by both U.S. and
international standards bodies:
ANSI C95.1 (1992) *
NCRP Report 86 (1986)
ICNIRP (1996)
