two expert organizations, the National Counsel on Radiation Protection
and Measurement (NCRP) and the Institute of Electrical and Electronics
Engineers (IEEE). In both cases, the recommendations were developed
by scientific and engineering experts drawn from industry, government,
and academia after extensive reviews of the scientific literature related
to the biological effects of RF energy.
The exposure Limit for wireless mobile phones employs a unit of
measurement known as the Specific Absorption Rate, or SAR. The
SAR is a measure of the rate of absorption of RF energy by the human
body expressed in units of watts per kilogram (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.
Tests for SAR are conducted using standard operating positions
specified by the FCC with the phone transmitting at its highest certified
power level in all tested frequency bands. Although 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. Because the
phone is designed to operate at multiple power levels 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 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 governmentadopted 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.
This device was tested for typical body-worn operations with the back
of the phone kept 0.79 inches (2.0 cm) between the user’s body and
the back of the phone. To comply with FCC RF exposure requirements,
a minimum separation distance of 0.79 inches (2.0 cm) must be
maintained between the user s body and the back of the phone. Third-
