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.
Before a new model phone is available for
sale to the public, it must be tested and
