What does “SAR” mean?
In1996,theFCC,workingwiththeFDA,theU.S.
Environmental Protection Agency, and other
agencies, established RF exposure safety guidelines
for wireless phones in the United States. Before
a wireless phone model is available for sale to
the public, it must be tested by the manufacturer
and certified to the FCC that it does not exceed
limits established by the FCC. One of these limits
is expressed as a Specific Absorption Rate, or
“SAR.”SAR is a measure of the rate of absorption of
RF energy in the body. Tests for SAR are conducted
with the phone transmitting at its highest power
levelinalltestedfrequencybands.Since1996,
the FCC has required that the SAR of handheld
wirelessphonesnotexceed1.6wattsperkilogram,
averaged over one gram of tissue. Although the SAR
is determined at the highest power level, the actual
SAR value of a wireless phone while operating can
be less than the reported SAR value. This is because
the SAR value may vary from call to call, depending
on factors such as proximity to a cell site, the
proximity of the phone to the body while in use, and
the use of hands-free devices. For more information
about SARs, see the FCC’s OET
