Absorption Rate (SAR). The SAR is a measure
of the rate of absorption of RF energy by the
human body expressed in units of watts per
kilogram (W/kg). The FCC requires wireless
phones to comply with a safety limit of 1.6
watts per kilogram (1.6 W/kg).
The FCC SAR limit incorporates a substantial
margin of safety to give additional protection
to the public and to account for any
variations in measurements.
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 reported 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 of the device.
