The exposure standard for mobile devices employs a unit of
measurement known as the Specific Absorption Rate, or SAR.
Tests for SAR are conducted using standard operating positions
with the device transmitting at its highest certified well below the
maximum value. Although the SAR is determined at the highest
certified power level, the actual SAR 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 base station, the
lower the power output of the device.
SAR values may vary depending on national reporting and
testing requirements and the network band. Use of device
accessories and enhancements may result in different SAR
values.
The SAR limit for mobile devices used by the public is 2.0 W/kg
averaged over 10 grams of body tissue. The guidelines
incorporate a substantial margin of safety to give additional
protection for the public and to account for any variations in
measurements.
The highest SAR value for this model phone tested for use is
xxxx mW/g.
