Safety
Consumer Information on SAR
(Specific Absorption Rate)
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 1.6 W/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 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. Because the phone is designed to operate at multiple
power levels 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 values are:
s Head: 1.22 W/kg
s
Body-worn/Hotspot: 1.29 W/kg
