Specific Absorption Rate (SAR)
Certification Information
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 RF 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
DRAFT For Internal Use Only
recommendations were developed by scientific
18
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 RF 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 SAR limit incorporates a substantial
margin of safety to give additional protection to
