Consumer information on SAR
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 sale to the public, it
must be tested and certified to the FCC that it does not exceed
the limit established by the government adopted requirement for
safe exposure. The tests are performed in positions and locations
