FCC 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 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.
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.
2）This device must accept any interference received, including interference that may cause
undesired operation.
Any changes or modifications not expressly approved by the party responsible for compliance
could void the user’s authority to operate the equipment.
Note: The manufacturer is not responsible for any radio or TV interference caused by
unauthorized modifications to this equipment. Such modifications could void the user’s authority
to operate the equipment.
FCC RF Radiation Exposure Statement:
This equipment complies with FCC RF radiation exposure limits set forth for an uncontrolled
environment. This device and its antenna must not be co-located or operating in conjunction with
any other antenna or transmitter.
“To comply with FCC RF exposure compliance requirements, this grant is applicable to only
Mobile Configurations. The antennas 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.”

This device is restricted in indoor environment only.
