Exposure to radio frequency energy
THIS DEVICE MEETS INTERNATIONAL GUIDELINES FOR EXPOSURE TO RADIO WAVES
Your mobile device is a radio transmitter and receiver. It is designed and manufactured not to exceed the limits 
for exposure to radio frequency (RF) recommended by international guidelines (ICNIRP). These limits are part of 
comprehensive guidelines and establish permitted levels of RF energy for the general population.
The guidelines were developed by independent scientific organisations 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 or health.
The exposure standard for mobile devices employs a unit of measurement known as the Specific Absorption 
Rate, or SAR. The SAR limit stated in the international guidelines is 2.0 W/kg*. Tests for SAR are conducted 
using standard operating positions with the device transmitting at its highest certified power level in all tested 
frequency bands. Although the SAR is determined at the highest certified power level, the actual SAR of the 
device while operating can be well below the maximum value. This is because the device is designed to operate 
at multiple power levels so as to use only the power required to reach the network. In general, the closer you are 
to a base station, the lower the power output of the device.
Before a phone model is available for sale to the public, compliance with the European R&TTE directive must be 
shown. This directive includes as one essential requirement the protection of the health and the safety for the 
user and any other person.
The highest SAR value for this device when tested for use at the ear is 0.662 W/kg.
This device meets RF exposure guidelines when used either in the normal use position against the ear or when 
positioned at least 1.5 cm away from the body. When a carry case, belt clip or holder is used for body-worn 
operation, it should not contain metal and should position the product at least 1.5 cm away from your body. In 
order to transmit data files or messages, this device requires a quality connection to the network. In some cases, 
transmission of data files or messages may be delayed until such a connection is available. Ensure the above 
separation distance instructions are followed until the transmission is completed.
The highest SAR value for this device when tested for use at the body is 0.560 W/kg.
* The SAR limit for mobile devices used by the public is 2.0 watts/ kilogram (W/kg) averaged over ten grams of 
body tissue. The guidelines incorporate a substantial margin of safety to give additional protection for the public 
and to account for any variations in measurements.  
SAR values may vary depending on national reporting requirements and the network band.
