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 specified 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) as required by the FCC for each model. The highest
SAR value for this model phone when tested for use at the ear is
1.34 W/Kg. While there may be differences between the SAR
levels of various phones and at various positions, they all meet the
government requirement.
