This device is intended only for OEM integrators under the following conditions:
1)The antenna must be installed such that 20 cm is maintained between the antenna and users, and
2)The antenna should be integral if the end device is intended to be operated in 5.15 ~ 5.25GHz frequency range.
As long as 2 conditions above are 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
This transmitter module is authorized only for use in device where the antenna may be installed such that 20 cm may be maintained between the
antenna and users (for example: Connector Board…etc.). The final end product must be labeled in a visible area with the following: “Contains
TX FCC ID: MXF-940307AT”.
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 end users must include the following information in a prominent location “ IMPORTANT NOTE: To
comply with FCC RF exposure compliance requirements, the antenna 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”.
The end product should include “The 5.15 to 5.35GHz band is restricted to indoor use only. Use of this product in outdoor could void the user’s
authority to operate this equipment.
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 equipment should be installed and operated with minimum distance 20cm
between the radiator & your body.
NOTE:
The WVM1104-Tx ( FCC ID: MXF-940307AT ) is limited in CH1~CH11 for 2.4 GHz by
specified firmware controlled in U.S.A.

The video transmission rate can be set to 4, 8 or 14 Mbps, or can be set to Limited Automatic or Fully
Automatic.
When set to Limited Automatic, the system will select automatically the highest possible video rate, up to
the value set in Byte0 of register 0x09. This setting may be used when the user wants to limit the system to 4
or 8 Mbps only, without trying to go to 14 Mbps.
When set to Fully Automatic, the system will select automatically the highest possible video rate.
Writing a value to register 0x09 commands the system to a desired video rate.

The Installation Process is required for sending MAC and Wireless ID parameters from a Tx unit to a Rx
unit. After the two units are “synchronized”, video/audio transfer can be done.
The normal installation process writes the Tx details in the Rx, in a list of recognized Tx units. (The Normal
process is usually done by pressing the Installation button at the Tx unit).
The temporary installation process is for testing while in production. The Rx writes the Tx details in the list
of recognized Tx units, but deletes the details when the Tx-Rx wireless link is cut off.

The Discrete I/O Test Mode is required for production testing of Tx and Rx units.
When in Discrete I/O test mode, the 4 LEDs (pin 1, 2, 3, 4 of the Discrete I/O port) are turned on.
When pin 5, 6, 7 or 8 of the Discrete I/O port is shorted to GND, the LED of pin 1, 2, 3 or 4, respectively, is
turned off. All 4 input pins can be shorted to GND in any combination.
