Specific Absorption Rate Data
The model wireless phone meets the government’s requirements for
exposure to radio waves.
Your wireless phone is a radio transmitter and receiver. It is designed and
manufactured not to 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 to assure the
safety of all persons, regardless of age or health.
The exposure standard for wireless mobile phones employs a unit of
measurement known as the Specific Absorption Rate, or SAR. The SAR
limit set by the FCC and by the Canadian regulatory authorities is
1.6 W/kg. 1 Tests for SAR are conducted using standard operating
positions accepted by the FCC and by Industry Canada 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, 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) reported to the FCC and available for review
by Industry Canada. The highest SAR value for this model phone when
