Your mobile is designed not to exceed the limits for exposure to radio waves
recommended by international guidelines. The guidelines are developed by an
independent scientific organization (ICNIRP) and include substantial safety margin
designed to assure the safety of all persons, regardless of age and health.
The radio wave exposure guidelines use a unit of measurement known as Specific
Absorption Rate, or SAR. The SAR Limit for mobile devices is 2.0W/kg. The highest
SAR values under the ICNIRP guideline for this model are (Maximum SAR for this
model and conditions under which it was recorded).
Body worn SAR testing has been carried out at a separation distance of 1.5cm. To
meet RF exposure guidelines during body-worn operations, the device should be
