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 the SAR is
determined at the highest certified power level, the
actual SAR level of the phone while operation can be
well below the maximum value. This is because the
phone 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 phone model is available for sale to the
public,
must be tested and certified to the FCC that
it
does not exceed the limit established by the
it
government-adopted requirement for safe exposure.
The tests are performed in positions and locations
the FCC for each model. (Body-worn measurements
may differ among phone models, depending upon
available accessories and FCC requirements). While
there may be differences between the SAR levels of
various phones and at various positions, they all meet
the government requirement for safe exposure
