manufactured not to exceed the emission limits for exposure to
radiofrequency (RF) energy set by the Federal Communications
Commission of the U.S. Government. These limits are part of
comprehensive guidelines and establish permitted levels of RF energy for
the general population. The 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 face is
0.700
W/Kg
and when
worn on the body, as described in this user guide, is
0.785W/Kg
(Body-worn measurements differ among phone models,
depending upon available accessories and FCC requirements). The
maximum scaled SAR in hotspot mode is
0.785W/Kg
. 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 the FCC
RFexposure guidelines. SAR information on this model phone is on file
with the FCC and can be found under the Display Grant section of

Additional information on Specific Absorption
Rates (SAR) can be found on the Cellular Telecommunications Industry
Asso-ciation (CTIA) web-site at http://www.wow-com.com. * In the
United States and Canada, the SAR limit for mobile phones used by the
public is 1.6 watts/kg (W/kg) averaged over one gram of tissue. The
standard incorporates a sub-stantial margin of safety to give additional
protection for the public and to account for any variations in
