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 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 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 mobile phones employs a unit of
measurement known as the Specific Absorption Rate (SAR). The
SAR limit set by the FCC is 1.6 W/kg
**
. 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 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.
Before a new model phone is available for sale to the public, it must
be tested and certified to the FCC that it does not exceed the
exposure limit established by the FCC. Tests for each model phone
are performed in positions and locations (e.g. at the ear and worn on
the body) as required by the FCC. For body worn operation, this
**. In the United States and Canada, the SAR limit for mobile
phones used by the public is 1.6 watts/kilogram (W/kg) averaged over
one gram of tissue. The standard incorporates a substantial margin of
safety to give additional protection for the public and to account for any
variations in measurements.
