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
