SAR tests are conducted using standard operating positions
accepted by the FCC with the phone transmitting at its highest
certified power level in all tested frequency bands. Although the
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. This is because the phone is designed to
operate at multiple power levels so as 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 new model phone is available for sale to the public, it
must be tested and certified to the FCC that it does not exceed
the exposure limit established by the FCC. Tests for each model
phone are performed in positions and locations (e.g. at the ear
and worn on the body) as required by the FCC.
For body-worn operation, this phone has been tested and meets
FCC RF exposure guidelines when used with an accessory that
contains no metal and that positions the mobile device a
minimum of 1.5 cm from the body.
Use of other accessories may not ensure compliance with FCC RF
exposure guidelines.
The FCC has granted an Equipment Authorization for this mobile
phone with all reported SAR levels evaluated as in compliance
with the FCC RF exposure guidelines. The maximum SAR values
for this model phone as reported to the FCC are:
WCDMA/GSM/EDGE
