Specific Absorption Rate
SAR
Your model wireless phone meets the governmental
requirements for exposure to radio waves.
Your wireless phone is a radio transmitter and receiver. It is designed and
manufactured to not exceed limits for exposure to radio frequency (RF) energy set by
the Federal Communications Commission (FCC) of the U.S. Government and by the
Canadian regulatory authorities. These limits are part of comprehensive guidelines
and establish permitted levels of RF energy for the general population. The
guidelines are based on standards that were developed by independent scientific
organizations through periodic and thorough evaluation of scientific studies. The
standards include a substantial safety margin designed for the safety of all persons,
regardless of age or health, and to account for any variations in measurements.
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 and by
the Canadian regulatory authorities is 1.6 watts per kilogram (W/kg), averaged over
one gram of tissue. Tests for SAR are conducted using procedures accepted by the
FCC and by Industry Canada with the phone transmitting at its highest certified
power level in all tested frequencies. Although the SAR is determined at the highest
certified power level, the actual SAR level of the phone while operating can be
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, the lower the power output.
Before a phone model is available for sale to the public in the U.S. and Canada, it
must be tested and certified to the FCC and Industry Canada that it does not exceed
the limit established by each government for safe exposure. The tests are performed
in positions and locations (e.g., at the ear and worn on the body) submitted to the
FCC and available for review by Industry Canada. The highest SAR value for this
model phone when tested for use at the ear is 1.59 W/kg, and when worn on the
body, as described in this guide, is 1.49 W/kg. Body-worn measurements can differ,
depending upon available accessories and regulatory requirements. The SAR
