(W/kg). The FCC requires wireless phones to comply with a safety
limit of 1.6 watts per kilogram (1.6 W/kg).
The FCC exposure 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 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
because the phone 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.
Before a new model phone is available for sale to the public, it must
be tested and certified to the FCC that it does not exceed the
exposure limit established by the FCC. Tests for each model phone
are performed in positions and locations (e.g. at the ear and worn on
the body) as required by the FCC.
