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.
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.
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:
This equipment complies with FCC radiation exposure limits set forth for an
uncontrolled environment.
This transmitter must not be co-located or operating in conjunction with any
other antenna or transmitter.

This device is intended only for OEM integrators under the following
conditions:
The transmitter module may not be co-located with any other transmitter or
antenna.
As long as conduction above is met, further transmitter test will not be required.
However, the OEM integrator is still responsible for testing their end-product
for any additional compliance requirements required with this module installed
(for example, digital device emissions, PC peripheral requirements, etc.).
IMPORTANT NOTE: In the event that these conditions can not be met (for
example certain laptop configurations or co-location with another transmitter),
then the FCC authorization is no longer considered valid and the FCC ID can
not be used on the final product. In these circumstances, the OEM integrator
will be responsible for re-evaluating the end product (including the transmitter)
and obtaining a separate FCC authorization.
End Product Labeling
The final end product must be labeled in a visible area with the following:
“Contains TX FCC ID: H8NWLF3020”.
Manual Information That Must be Included
The OEM integrator has to be aware not to provide information to the end user
regarding how to install or remove this RF module in the users manual of the
end product which integrate this module.
The users manual for OEM integrators must include the following information
in a prominent location “ IMPORTANT NOTE: To comply with FCC RF
exposure compliance requirements. The antenna must not be co-located or
operating in conjunction with any other antenna or transmitter.
