59 Health and safety information
* In the United States, the SAR
limit for mobile phones used
by the public is 1.6 watts/
kilogram (W/kg) averaged
over one gram of tissue.
The standard incorporates a
substantial margin of safety
to give additional protection
for the pubilc and to account
for any variations in
measurements.
SAR certification information
Your wireless phone is a radio
transmitter and receiver. It is
designed and manufactured not to
exceed limits for exposure to radio
frequency (RF) energy set by the
Federal Communications
Commission (FCC) 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 or 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, the
lower the power output.
Before a phone model is availble
for sale to the public in the U.S., it
must be tested and certified to the
FCC that it does not exceed the
limit established for safe exposure.
The tests are performed in positions
and locations (e.g., at the ear and
worn on the body) reported to the
FCC.
The highest SAR values for this
model phone are:
- Head : 0.33W/kg
- Body-worn : 0.36W/kg
