Specific Absorption Rate information
YOUR MOBILE DEVICE MEETS INTERNATIONAL GUIDELINES FOR
EXPOSURE TO RADIO WAVES.
Your mobile device is a radio transmitter and receiver. It is designed
not to exceed the limits for exposure to radio waves (radio frequency
electromagnetic fields) recommended by international guidelines. The
guidelines were developed by an independent scientific organization
(ICNIRP) and include a substantial safety margin designed to assure the
safety of all persons, regardless of age and health.
The radio wave exposure guidelines use a unit of measurement known as the
Specific Absorption Rate, or SAR. The SAR limit for mobile devices is 2W/kg.
Tests for SAR are conducted using standard operating positions with the device
transmitting at its highest certified power level in all tested frequency bands.
The highest SAR values under the ICNIRP guidelines for your device model are
listed below:

During use, the actual SAR values for your device are usually well below
the values stated. This is because, for purposes of system eciency and to
minimize interference on the network, the operating power of your mobile
device is automatically decreased when full power is not needed for the data
connection.
The lower the power output of the device, the lower its SAR value.
If you are interested in further reducing your RF exposure then you can easily
do so by limiting your usage or simply using a hands-free kit to keep the
device away from the body.
