Additional safety information
the limits for exposure to radio waves
recommended by international
guidelines. These guidelines were
developed by the independent scientific
organisation 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 0.97 W/kg.
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
