The exposure limit set by the FCC for wireless 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 unites 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 wireless 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. Health and safety information
Exposure to Radio Frequency (RF) Signals
Certification Information (SAR)
This product can be embedded 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.
