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
