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 at the ear is
0.68 W/kg.
Use of device accessories and enhancements may result in
different SAR values. SAR values may vary depending on
national reporting and testing requirements and the
