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
radiofrequency (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/kg.* 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 (e.g., at the ear and worn on the
body) as required by the FCC for each model. The highest SAR value for
this model phone when tested for use at the ear is 0.86 W/Kg and when
worn on the body, as described in this users guide, is 0.68 W/Kg.
(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.
