What does "SAR" mean?
In 1996, the FCC, working with
the FDA, the U.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
level in all tested frequency bands.
Since 1996, the FCC has required
that the SAR of handheld
wireless phones not exceed 1.6
watts per kilogram, 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. 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 (e.g., at the ear and worn
on the body) as required by the
FCC for each model.
The highest SAR value for this
model phone when tested for use
at the ear is 0.70 W/kg and when
worn on the body, as described
in this user guide, is 1.25 W/kg
(body-worn measurements differ
among phone models, depending
upon available accessories and
FCC requirements).
