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)
