Your phone contains a transmitter and a receiver. When it is ON, it receives and 
transmits RF energy. When you communicate with your phone, the system 

handling your call controls the power level at which your phone transmits. 

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 organisation 

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 SAR limit for mobile devices is 2 W/kg and the highest SAR value for 
this device when tested at the ear was 0.711 W/kg*. As mobile devices offer a 

range of functions, they can be used in other positions, such as on the body as 
described in this user guide**. 

As SAR is measured utilising 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 [EN50360-2001], [EN62209-1:2006] 

and [IEC 62209-2:2008(106/162/CDV)]. 
** Please see page 2 about body worn operation. 

Important safety information regarding radiofrequency radiation (RF) exposure 

 

To ensure compliance with RF exposure guidelines the phone must be used with a 
minimum of 15 mm separation from the body.
