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 1.6W/kg.* 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 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 1.38 W/kg and when worn on the body, as described in
this user guide, the highest SAR value is 1.26 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. The FCC has
granted an Equipment Authorization for this model phone
with all reported SAR levels evaluated as in compliance with
