Your wireless handheld portable telephone is a low power radio transmitter and
receiver. When it is ON, it receives and also sends out radio frequency (RF) signals.
In August 1996, the Federal Communications Commissions (FCC) adopted RF expo-
sure guidelines with safety levels for hand-held wireless IP endpoints. Those guide-
lines are consistent with the safety standards previously set by both U.S. and
international standards bodies:
•
ANSI C95.1 (1992) American National Standards Institute
•
NCRP - Report 86 (1986) National Council on Radiation Protection and Mea-
surements
•
ICNIRP (1996) International Commission on Non-Ionizing Radiation Protection;
•
DHWC - Safety Code 6 Department of Health and Welfare Canada
Those standards were developed by independent scientific organizations through peri-
odic and thorough evaluation of scientific studies. The standards include a substantial
safety margin designed to assure the safety of all persons, regardless of age and
health. The exposure standard for wireless mobile endpoints employs a unit of mea-
surement known as the Specific Absorption Rate, or SAR. The SAR limit set by the
FCC is 1.6W/kg.
specified by the FCC with the endpoint transmitting at its highest certified power
level in all tested frequency bands. Although the SAR is determined at the highest
certified power level, the actual SAR level of the endpoint while operating can be
well below the maximum value. This is because the endpoint is designed to operate at
multiple power levels so as to use only the power required to reach the network. In
general, the closer you are to a wireless base station antenna, the lower the power out-
put. Before an endpoint model is available for sale to the public, it must be tested and
certified to the FCC that it does not exceed the limit established by the government-
adopted requirement for safe exposure. The tests are performed in positions and loca-
tions (e.g., at the ear and worn on the body) as required by the FCC for each model.
While there may be differences between the SAR levels of various endpoints and at
various positions, they all meet the government requirement for safe exposure. The
FCC has granted an Equipment Authorization for this model endpoint with all
reported SAR levels evaluated as in compliance with the FCC RF emission guide-
lines. SAR information on this model endpoint is on file with the FCC and can be
found under the Display Grant section of http://www.fcc.gov/oet/fccid after searching
on FCC ID IYGRNP2400.
1. In the United States and Canada, the SAR limit for mobile endpoints used by the public is 1.6
watts/kg (W/kg) averaged over one gram of tissue. The standard incorporates a substantial margin
of safety to give additional protection for the public and to account for any variations in measure-
ments.
