Before a phone model is available for
sale to the public, it must be tested
and certifi ed 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 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.
The highest SAR value for this model
phone when tested for use at the
ear is 0.70 W/kg and when worn on
the body, as described in this user's
manual, is 1.25 W/kg. While there
may be differences between SAR
levels of various phones and at various
positions, they all meet the government
requirement for safe exposure.
