Specific Absorption Rate (SAR)
Certification Information
Your 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 scientic and engineering experts drawn
from industry, government, and academia after
extensive reviews of the scientic 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 Specic 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 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 device
transmitting at its highest certied power level in
all tested frequency bands. Although the SAR is
determined at the highest certied power level,
the actual SAR level of the device while operating
