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
