FCC Statement

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 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 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.

IMPORTANT NOTE:

Any changes or modification to this unit not expressly approved by the party responsible for

compliance could void the user’s authority to operate the equipment.

FCC RF RADIATION EXPOSURE STATEMENT:

This module must be installed and operated in accordance with provided instructions and the antenna used for this
transmitter must be installed to provied 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-uses and installers must be provide
with antenna installation instructions and transmitter operating conditions for satisfying RF exposure compliance.

LABELING REQUIREMENTS:

1.

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.

2. Host device of OEM integrator must be labeled with:

1. To comply with FCC RF radiation exposure requirements, the antenna(s) used for this module must not be

co-located or operating in conjunction with any other antenna or transmitter.

2. The end user has to be informed: 1). to keep at least 20 cm separation with the antenna while this end

product is installed and operated. 2). the FCC radio-frequency exposure guidelines for an uncontrolled
environment can be satisfied. 3). any changes or modifications not expressly approved by the manufacturer
could void the user’s authority to operate this equipment.

3. If the size of the end product is smaller than 8x10cm, then additional FCC part 15.19. statement is required

to be available in the user’s manual: this device complies with part 15 of 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.

4. Any changes or modifications not expressly approved by the manufacturer could void the user’s authority to

operate this equipment.
