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 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 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 RF 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 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 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 reported 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 of the phone.
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 SAR 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.
