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 0.71 W/kg and when
worn on the body, as described in this user guide,
is 1.37 W/kg (body-worn measurements differ
