Radio Frequency (RF) Energy 

This model USB meets the government’s requirements for exposure to radio waves. 
This USB modem is designed and manufactured not to exceed the emission limits for 
exposure to radio frequency (RF) energy set by the Federal Communications 
Commission of the U.S. Government: 
The exposure standard for wireless mobile USB modems employs a unit of 
measurement known as the Specific Absorption Rate, or SAR.    The SAR limit set by 
the FCC is 1.6W/kg.  *Tests for SAR are conducted using standard operating 
positions accepted by the FCC with the USB modem 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 level of the USB modem while 
operating can be well below the maximum value.    This is because the USB modem is 
designed to operate at multiple power levels so as to use only the poser required to 
reach the network.    In general, the closer you are to a wireless base station antenna, 
the lower the power output. 
The highest SAR value for the model USB modem as reported to the FCC when 
tested for use at worn on the body is 

0.831

 W/kg (Body-worn measurements differ 

among USB modem models, depending upon available enhancements and FCC 
requirements.) 
While there may be differences between the SAR levels of various USB modems and 
at various positions, they all meet the government requirement. 
The FCC has granted an Equipment Authorization for this model USB modem with all 
reported SAR levels evaluated as in compliance with the FCC RF exposure guidelines.   
SAR information on this model USB modem is on file with the FCC and can be found 
under the Display Grant section of http://www.fcc.gov/oet/fccid after searching on   

FCC ID: KA2WM158B1

For body worn operation, this USB modem has been tested and meets the FCC RF
