Exposure to Radio Frequency (RF) Signals
Your wireless phone is a radio transmitter and receiver. It is designed
and manufactured not to exceed the emission limits for exposure to
radio frequency (RF) energy set by the Federal Communications
Commission (FCC) of the U.S. Government. These limits are part of
comprehensive guidelines and establish permitted levels of RF
energy for the general population. The guidelines are based on the
safety standards that were developed by independent scientific
organizations through periodic and thorough evaluation of scientific
studies.
The standards include a substantial safety margin designed to
assure the safety of all persons, regardless of age and health.
The exposure standard for wireless phones employs a unit of
measurement known as Specific Absorption Rate (SAR). The SAR
limit recommended by the FCC is 1.6W/kg.
*
SAR tests are conducted using standard operating positions
specified 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 of the phone.

In the U.S.A. and Canada, the SAR limit for mobile
phones used by the public is 1.6 watts/kg (W/kg) aver-
aged over one gram of tissue. The standard incorpo-
rates a substantial margin of safety to give additional
protection for the public and to account for any varia-
tions in measurements.
