conducted using standard operating positions speci
fi
ed by the FCC
with the phone transmitting at its highest certi
fi
ed power level in all
tested frequency bands. Although SAR is determined at the highest
certi
fi
ed 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 certi
fi
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 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 guide, is 1.27 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.
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. SAR information on this model
phone is on
fi
le with the FCC and can be found under the Display
Grant section of http://www.fcc.gov/oet/fccid after searching on
FCC ID ZNFE960. Additional information on Speci
