Specific Absorption Rate (SAR) Information
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 Com-
munications 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 Pro-
tection 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 organi-
zations 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.

Tests for SAR are con-
ducted 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
1. 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 protec-
tion for the public and to account for any variations in measurements.
