Exposure to Radio Frequency (RF) Signals
Certification Information (SAR)
Your wireless
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 Counsel
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
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
device
while operating can be well below the maximum value. This is because the
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
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
device
are performed in positions and locations as required by the FCC.
Non-compliance with the above restrictions may result in violation of FCC RF exposure
guidelines.
