This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1)
interference, and (2) this device must accept any interference received,
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This
Federal Communication Commission Interference Statement
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
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
to try to correct the interference by one 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.
This device may not cause harmful
including interference that may cause undesired operation.
FCC Caution: Any changes or modifications not expressly approved by the party responsible for
compliance could void the user's authority
to operate this equipment.
IMPORTANT NOTE:
FCC Radiation Exposure Statement:
equipment should be installed
and operated with minimum distance 20cm between the radiator & your body.
This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.
" This equipment must be installed and operated in accordance with provided instructions and the
antenna(s) used for this transmitter must be installed to provide a separation distance of at least 20 cm
from all persons and must not be co-located or operating in conjunction with any other antenna or
transmitter. End-users and installers must be provide with antenna installation instructions and transmitter
operating conditions for satisfying RF exposure compliance. "
