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 determined at the
highest certiied power level, the actual SAR
