Consumer Information on SAR
(Specific Absorption Rate)
This Model Phone Meets the Government’s Requirements for
Exposure to Radio Waves.
Your wireless phone is a radio transmitter
and receiver. It is designed and manufactured not to exceed the emission
limits for exposure to radiofrequency (RF) energy set by the Federal
Communications Commission (FCC) of the U.S. Government.
These FCC exposure limits are derived from the recommendations of
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
