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