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 Specific 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 file 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.

equipment.
Note: This equipment has been tested and found to comply with the
limits for a Class B digital device, pursuant to part 15 of the FCC Rules.
These limits are designed to provide reasonable protection against
harmful interference in a residential installation. This equipment
generates, uses, and can radiate radio frequency energy and, if not
installed and used in accordance with the instructions, may cause
harmful interference to radio communications. However, there is no
guarantee that interference will not occur in a particular installation. If
this equipment does cause harmful interference to radio or television
reception, which can be determined by turning the equipment off
and on, the user is encouraged to try to correct the interference by
one or more of the following measures:
•   Reorient or relocate the receiving antenna.
•   Increase the separation between the equipment and receiver.
•   Connect the equipment into an outlet on a circuit different from 
that to which the receiver is connected.
•   Consult the dealer or an experienced radio/TV technician for help.
