Radio Frequency (RF) Energy
This model device meets the government’s requirements for exposure to radio waves.
This device 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 devices employs a unit of measurement known as the Specific
Absorption Rate, or SAR. The SAR limit set by the FCC is 1.6 W/kg. *Tests for SAR are conducted using
standard operating positions accepted by the FCC with the device 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 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 worn on the body, as described
in this user guide, is
1.16
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
