SAR certification information
The device meets international guidelines for exposure to radio waves.
Your phone is a radio transmitter and receiver. I
t‟s designed not to exceed the limits
for exposure to radio waves recommended by international guidelines. The guidelines
were developed by ICNIRP, an independent technical standards body, and include
margins designed to assure the protection of all persons, regardless of age and
health.
These guidelines use a unit of measurement known as Specific Absorption Rate,
(SAR). The SAR limit for mobile devices is 1.6 W/kg and the highest SAR value for
this device when tested was

As SAR is measured when the phone is on its highest transmitting power, the actual
SAR of this device while operating normally is typically below the levels shown above.
This is because your phone automatically changes its power level to ensure it only
uses the minimum level required to reach the network.
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.
1. The tests are carried out in accordance with
IEEE standard P1528-2003
