Safety Guidelines
Consumer Information on SAR
(Specific Absorption Rate)
This Model Phone Meets the
Government's Requirements for
Exposure to Radio Waves.
Your wireless phone is a radio transmitter
and receiver. It is designed and
manufactured not to exceed the emission
limits for exposure to radiofrequency (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 for
wireless mobile phones employs a unit
of measurement known as the Specific
82
Absorption Rate, or 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.
Tests for SAR are conducted using standard
operating positions specified by the FCC with
the phone transmitting at its highest certified
power level in all tested frequency bands.
Although 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. Because the phone is
designed to operate at multiple power levels
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 phone model is available for sale
to the public, it must be tested and certified
to the FCC that it does not exceed the limit
