96  Specific Absorption Rate Data 

Your mobile phone is a radio transmitter and receiver. It is designed and 
manufactured not to exceed limits for exposure to radio frequency (RF) energy. 
These limits are part of comprehensive guidelines and establish permitted levels 
of RF energy for the general population. The guidelines are based on standards 
that were developed by independent scientific organizations through periodic 
and thorough evaluation of scientific studies. The guidelines include a 
substantial safety margin designed to assure the safety of all persons, 
regardless of age and health. 

The exposure standard for mobile phones employs a unit of measurement 
known as the Specific Absorption Rate, or SAR. Under the guidelines for your 
phone model, the SAR limit is 2.0 W/kg.

 Tests for SAR are conducted in 

accordance with CENELEC

 testing procedures using standard operating 

positions with the phone transmitting at its highest certified power level in all 
tested frequency bands. Although the SAR is determined at the highest

 The SAR limit recommended by international guidelines (ICNIRP) for mobile 

phones used by the public is 2.0 watts/kilogram (W/kg) averaged over ten 
grams of tissue. The limit incorporates a substantial margin for safety to give 
additional protection for the public and to account for any variations in 
measurements.
