Exposure to Radio Frequency (RF) Signals
Certification Information (SAR)
Your wireless phone is a radio transmitter and receiver. It is designed and
manufactured not to exceed the exposure limits for radio frequency (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 set by the FCC for wireless mobile phones employs a unit
of measurement known as the Specific Absorption Rate (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.
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.
