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.
