set by the Federal Communications Commission of the U.S.
Government:
The exposure standard for wireless mobile phones employs a
unit of measurement known as the Specific Absorption Rate, or
SAR. The SAR limit set by the FCC is .6 W/kg. Tests for SAR
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.
The highest SAR value for this model phone as reported to
the FCC when tested for use at the ear is 1.230 W/kg and
when worn on the body, as described in this user guide, is
1.000 W/kg (Body-worn measurements differ among phone
models, depending upon available enhancements and FCC
requirements.)
While there may be differences between the SAR levels of
individual phones and at various positions, they all meet the
government requirement.
The FCC has granted an Equipment Authorization for this model
phone with all reported SAR levels evaluated as in compliance
with the FCC RF exposure guidelines. SAR information on this
model phone is on file with the FCC and can be found under
the Display Grant section of http://www.fcc.gov/oet/ea/fccid after

For body worn operation, this phone has been tested and meets
the FCC RF exposure guidelines for use with an accessory that
contains no metal and that positions the handset a minimum of .5
