the sar limit set by the industry canada is 1.6 W/kg. * tests for
sar are conducted using standard operating positions with the
phone transmitting at its highest certified power level in all tested
frequency bands.
Although 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. Because the phone is designed to operate at
multiple power levels 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 for each model.
the highest sar value for this model phone when tested for use at
the ear is 0.56 W/kg and when worn on the body, as described in
this user's manual, is 1.27 W/kg. (Body-worn measurements differ
among phones models, depending upon available accessories and
Fcc/ic 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 and industry canada have granted an equipment
authorization for this model phone with all reported sar levels
evaluated as in compliance with the relevant rF emission
guidelines. SAR information on this model phone is on file with the
Fcc and can be found under the display grant section of http://
