Radio Frequency (Rf) Energy - AT&T WF721 User Manual

Radio frequency (RF) energy

This 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 mobile devices employs a
unit of measurement known as the Specifi c Absorption Rate, or
SAR. The SAR limit set by the FCC is 1.6 W/kg.*
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
device with all reported SAR levels evaluated as in compliance
with the FCC RF exposure guidelines. SAR information on
this device is on fi le with the FCC and can be found under the
Display Grant section of http://www.fcc.gov/oet/ea/fccid/
after searching FCC ID: SRQ-WF721.
* 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 power required to
reach the network. In general, the closer you are to a wireless base station
antenna, the lower the power output.
