Specific Absorption Rate (SAR) Certification
Information
Your 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 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 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 set by the FCC for wireless mobile devices
employs a unit of measurement known as the Specific
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 exposure 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 certified power level in all tested frequency bands.
Although the SAR is determined at the highest certified power
level, the actual SAR level of the mobile device while operating
can be well below the maximum value. This is because the
mobile device is designed to operate at multiple power levels so
as 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 new model mobile device is available for sale to the
public, it must be tested and certified to the FCC that it does not
exceed the exposure limit established by the FCC. Tests for each
model of a device are performed in positions and locations (e.g.
near the body) as required by the FCC.
For typical operations, this mobile device has been tested and
meets FCC RF exposure guidelines.
Use of other accessories may not ensure compliance with FCC RF
exposure guidelines.
