energy by the human body expressed in
units of watts per kilogram (W/kg). The
FCC requires wireless devices to comply
with a safety limit of 1.6 watts per
kilogram (1.6 W/kg).
The FCC SAR limit incorporates a
substantial margin of safety to give
additional protection to the public and to
account for any variations in
measurements.
SAR tests are conducted using standard
operating positions accepted by the FCC
with the device 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
device while operating can be well below
the maximum reported value. This is
because the device 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 of the device.
Before a new model device is available
for sale to the public, it must be tested
and certified to the FCC that it does not
exceed the SAR limit established by the
