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 for wireless mobile phones employs a unit of
measurement known as the Specific Absorption Rate, or 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.
Tests for SAR are conducted using standard operating positions
specified by the FCC with the phone transmitting at its highest
certified power level in all tested frequency bands. Although 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. Because the phone is designed to operate at multiple power
levels 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 phone model is available for sale to the public, it must be
tested and certified to the FCC that it does not exceed the limit
established by the government adopted requirement for safe
exposure. The tests are performed in positions and locations (e.g.,
at the ear and worn on the body) as required by the FCC for each
model.
This device was tested for typical body-worn operations with the
back of the phone kept 0.79 inches (2.0 cm) between the user's
body and the back of the phone. To comply with FCC RF exposure
requirements, a minimum separation distance of 0.79 inches (2.0
cm) must be maintained between the user's body and the back of
the phone. Third-party belt-clips, holsters, and similar accessories
