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.
