203 Safety
• 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
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
phones.
Exposure to Radio Frequency Signal
Your wireless handheld portable phone 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 phones.
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)
* American National Standards Institute; National Council on Radiation
Protection and Measurements; International Commission on Non-Ionizing
Radiation Protection
Those standards were based on comprehensive and periodic evaluations of
the relevant scientific literature. For example, over 120 scientists,
engineers, and physicians from universities, government health agencies,
and industry reviewed the available body of research to develop the ANSI
Standard (C95.1).
