Radio frequency (RF) signals
THIS MODEL 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 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 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, or SAR. The SAR limit set by the FCC
is 1.6W/kilogram.* Tests for SAR 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 phone model is available for sale to the public, it must be tested
and certified to the FCC that it does not exceed the limit established by
the government-adopted requirement for safe exposure. The tests are
performed in positions and locations (for example, at the ear and worn on
the body) as required by the FCC for each model. The highest SAR value for
this model phone as reported to the FCC when tested for use at the ear is
0.74 W/kilogram and when worn on the body, as described in this user
guide, is 0.84 W/kilogram. (Body-worn measurements differ among phone
models, depending upon available accessories and FCC requirements). While
there may be differences between the SAR levels of various phones and at
various positions, they all meet the government requirement.
