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 1.6 W/kg.
measurement known as the Specific Absorption Rate, or SAR.
The SAR limit for mobile devices is 1.6 W/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 FCC 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 efficiency 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 call. The lower
the power output of the device, the lower its SAR value.

Body-worn SAR testing has been carried out using an
approved accessory or at a separation distance of 2.5 cm
(1 inch). To meet RF exposure guidelines during body-worn
operation, the device should be in an approved accessory or
positioned at least 2.5 cm (1 inch) away from the body. If you
are not using an approved accessory, ensure that whatever
product is used is free of any metal and that it positions the
phone at least 2.5 cm (1 inch) away from the body.

The World Health Organization has stated that present scientific
information does not indicate the need for any special
precautions for the use of mobile devices. They recommend
that if you are interested in further reducing your 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 head and
body.
