What does "SAR" mean?
In 1996, the FCC, working with the FDA, the U.S. Environmental
Protection Agency, and other agencies, established RF
exposure safety guidelines for wireless phones in the United
States. Before a wireless phone model is available for sale to
the public, it must be tested by the manufacturer and certified
to the FCC that it does not exceed limits established by the
FCC. One of these limits is expressed as a Specific Absorption
Rate, or "SAR. " SAR is a measure of the rate of absorption
of RF energy in the body. Tests for SAR are conducted with
the phone transmitting at its highest power level in all tested
frequency bands. Since 1996, the FCC has required that the
SAR of handheld wireless phones not exceed 1.6 watts per
kilogram, averaged over one gram of tissue.
Although the SAR is determined at the highest power level,
the actual SAR value of a wireless phone while operating can
be less than the reported SAR value. This is because the SAR
value may vary from call to call, depending on factors such
as proximity to a cell site, the proximity of the phone to the
body while in use, and the use of hands-free devices. 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 0.67 W/kg and when worn on the body,
as described in this user guide, is 0.52 W/kg (body-worn
measurements differ among phone models, depending upon
available accessories and FCC requirements).
While there may be differences between 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 RF emission guidelines. SAR
