Your wireless phone is a radio transmitter and receiver. It is
designed and manufactured not to exceed the exposure limits for
Radio Frequency (RF) energy set by the Federal Communications
Commission (FCC) of the U.S. Government.

These FCC RF exposure limits are derived from the
recommendations of two expert organizations: the National

Council on Radiation Protection and Measurement (NCRP) and
the Institute of Electrical and Electronics Engineers (IEEE). In both
cases, the recommendations were developed by scientific and
engineering experts drawn from industry, government, and
academia after extensive reviews of the scientific literature
related to the biological effects of RF energy.

The RF exposure limit set by the FCC for wireless mobile phones
employs a unit of measurement known as the Specific
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
phone.
