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, generally, 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 0.39 inches (1.0 cm) between
the user’s body and the back of the phone. To comply with FCC RF exposure
