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 Council 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, generally, the closer you are to a wireless base
station antenna, the lower the power output. Before a phone model is available for
