Specific Absorption Rate (SAR) Information
Your wireless 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 exposure guidelines with safety
levels for hand-held wireless phones. Those guidelines 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 Measurements
• 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 periodic 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 phones employs a unit of
measurement known as the Specific Absorption Rate, or SAR. The
SAR limit set by the FCC is 1.6W/kg.
In the United States and Canada, the SAR limit for mobile phones
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 measurements.
Tests for SAR are conducted using standard operating positions
specified by the FCC with the phone 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 phone while operating can be well below the maximum value.
This is because the phone 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 output. Before a phone 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 locations
