CE SAR Compliance 
This device meets the EU requirements (1999/519/EC) on the limitation of exposure of the general public to 
electromagnetic fields by way of health protection.   
 
The limits are part of extensive recommendations for the protection of the general public. These recommendations have 
been developed and checked by independent scientific organizations through regular and thorough evaluations of 
scientific studies. The unit of measurement for the European Council's recommended limit for mobile devices is the 
"Specific Absorption Rate" (SAR), and the SAR limit is 2.0 W/ kg averaged over 10 gram of body tissue. It meets the 
requirements of the International Commission on Non-Ionizing Radiation Protection (ICNIRP).   
 
For body worn operation, this device has been tested and meets the ICNIRP exposure guidelines and the European 
Standard EN 62311 and EN 62209-2, for use with dedicated accessories. Use of other accessories which contain metals 
may not ensure compliance with ICNIRP exposure guidelines. 
 
SAR is measured with the device at a separation of 1.5 cm to the body, while transmitting at the highest certified output 
power level in all frequency bands of the mobile device.
