level, the actual SAR level 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 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 device as reported to the FCC 
when tested for use at the ear is 1.53 W/kg and when worn on the body, 
as described in this user guide, is 0.418 W/kg (Body-worn 
measurements differ among device models, depending upon available 
enhancements and FCC requirements.) 
 
While there may be differences between the SAR levels of various 
devices and at various positions, they all meet the government 
requirement. 
 
The FCC has granted an Equipment Authorization for this model 
device with all reported SAR levels evaluated as in compliance with the 
FCC RF exposure guidelines.  SAR information on this model device 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: Q78-ZTEC339. 
 
For body worn operation, this device has been tested and meets the 
FCC RF exposure guidelines for use with an accessory that contains no
