8 Important Health, Safety and Warranty Information
Speciic Absorption Rate (SAR)
Certiication Information
Your wireless mobile device 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 recommendations were developed by
scientiic and engineering experts drawn
from industry, government, and academia
after extensive reviews of the scientiic
literature related to the biological effects of
RF energy.
The RF exposure limit set by the FCC for
wireless mobile devices employs a unit
of measurement known as the Speciic
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 devices 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 the public and to
account for any variations
in measurements.
SAR tests are conducted using standard
operating positions accepted by the FCC
with the mobile device transmitting at its
highest certiied power level in all tested
frequency bands. Although the SAR is
