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 1.1 W/kg (Body-worn measurements differ among device models,
depending upon available enhancements and FCC requirements.)
For body worn operation, this device has been tested and meets the FCC RF exposure guidelines
for use with an accessory that contains no metal and the positions the handset a minimum of 5
mm from the body. Use of other enhancements may not ensure compliance with FCC RF
exposure guidelines. If you do not use a body-worn accessory and are not holding the phone at
the ear, position the handset a minimum of 5 mm from your body when the phone is switched on.
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/ea/fccid/ after searching on
