Safety
guidelines are based on standards that were developed by
independent scientific organizations through periodic and
thorough evaluation of scientific studies. The standards include
a substantial safety margin designed to assure the safety of all
persons, regardless of age and health.
The exposure standard for wireless mobile phones employs a
unit of measurement known as the Specific Absorption Rate,
or SAR. The SAR limit set by the FCC is 1.6 W/kg.* Tests for
SAR are conducted 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 operating 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, 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.
The highest SAR value for this model phone when tested for
use at the ear is 0.524 W/Kg and when worn on the body,
as described in this user guide, is 0.527 W/Kg. (Body-worn
measurements 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.
