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 0.58 W/kg and when
worn on the body, as described in this user guide,
is 1.02 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.
