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: Q78-Z700.
* 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.

FCC Regulations

This device complies with part 15 of the FCC Rules. Operation is
subject to the following two conditions: (1) This device may not
cause harmful interference, and (2) this device must accept any
interference received, including interference that may cause
undesired operation.
This device 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.
Changes or modifications not expressly approved by the party
responsible for compliance could void the user's authority to
operate the equipment.
