12. TECHNICAL INFORMATION
12.1 Specific Absorption Rate Data
This model meets international guidelines for exposure to radio waves.
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 scientific 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 the Specific Absorption Rate,
or SAR. The ICNIRP SAR limit for mobiles devices used by the general public is 2
W/kg and the highest SAR values for this device when tested, were Body: <value>
W/kg, Head: <value> W/kg.>*
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 level required to reach the network.
While there may be differences between the SAR levels of various phones and at
various positions, they all meet the governmental requirements for safe exposure.
Please note that improvements to this product model could cause differences in the
SAR value for later products; in all cases, products are designed to be within the
guidelines.
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. They
note that if you want to reduce your exposure then you can do so by limiting the
