Specific Absorption Rate (SAR)
Certification Information
Your wireless phone 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 phones
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
phones 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 phone 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 phone while
operating can be well below the maximum value. This is
because the phone 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 phone 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 phone are performed in positions and locations
(e.g. at the ear and worn on the body) as required by the
FCC.
For body-worn operation, this phone has been tested and
meets FCC RF exposure guidelines when used with an
accessory that contains no metal and that positions the
mobile device a minimum of 1.0 cm from the body.
