Your mobile device is a radio transmitter and receiver. It is
designed not to exceed the limits for exposure to radio waves
recommended by international guidelines. These guidelines were
developed by the independent scientific organization ICNIRP and
include safety margins designed to assure the protection of all
persons, regardless of age and health.
The exposure guidelines for mobile devices employ a unit of
measurement known as the Specific Absorption Rate or SAR. The
SAR limit stated in the ICNIRP guidelines is 2.0 watts/kilogram
(W/kg) averaged over 10 grams of tissue. 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 actual SAR level of an operating device can
be below the maximum value because the device is designed to
use only the power required to reach the network. That amount
changes depending on a number of factors such as how close you
are to a network base station. The highest SAR value under the
ICNIRP guidelines for use of the device at the ear is 0.69 W/kg,
which is in compliance with the requirement from the National
Standard GB 21288-2007.
Use of device accessories may result in different SAR values. SAR
values may vary depending on national reporting and testing
requirements and the network band. Additional SAR information
