Certification Information (SAR) 

THIS DEVICE MEETS THE GOVERNMENT'S 
REQUIREMENTS FOR EXPOSURE TO RADIO 
FREQUENCY ELECTROMAGNETIC FIELD. 
Your device is a low-power radio transmitter and 

receiver. When it is turned on, it emits low levels of 
radio frequency energy (also known as radio waves or 
radio frequency fields). 
Governments around the world have adopted 

comprehensive international safety guidelines, 
developed by scientific organizations, e.g. 
International Commission on Non-Ionizing Radiation 

Protection (ICNIRP) and Institute of Electrical and 
Electronics Engineers Inc. (IEEE), through periodic 

and thorough evaluation of scientific studies. These 
guidelines establish permitted levels of radio wave 
exposure for the general population. The levels 

include a safety margin designed to assure the safety 
of all persons, regardless of age and health, and to 
account for any variations in measurements. 
Specific Absorption Rate (SAR) is the unit of 

measurement for the amount of radio frequency 
energy absorbed by the body when using a device. 
The SAR value is determined at the highest certified 

power level in laboratory conditions, but the actual 
SAR level of the device while being operated can be 
well below the value. This is because the device is 

designed to use the minimum power required to reach 
the network.
