Specic Absorption Rate (SAR)
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 scientic
organization ICNIRP and include safety
margins designed to assure the protection of
all persons, regardless of age and health.
The guidelines use a unit of measurement
known as Specic Absorption Rate, or SAR.
The SAR limit for mobile devices is 2 W/kg and
the highest SAR value for this device when
tested at the body was 0.99 W/kg* with 5 mm
distance.
As SAR is measured utilizing the device’s
highest transmitting power, the actual SAR of
this device while operating is typically below
that indicated above. This is due to automatic
changes to the power level of the device
to ensure it only uses the minimum power
required to communicate with the network.
* The tests are carried out in accordance with
EN 50566, EN 62209-2, EN 50665, EN 62479
and EN 50663.
