Integration instructions for host product manufacturers according to KDB 996369 D03OEM Manual v01
2.2 List of applicable FCC rules
FCC Part 15 Subpart C 15.249 &15.207 &15.209.
Specific operational use conditions
The module can be used for mobile applications with a maximum 0dBi antenna. The host manufacturer installing this module into their product must ensure that the final composite product complies with the FCC requirements by a technical assessment or evaluation to the FCC rules, including the transmitter operation. The host manufacturer has to be aware not to provide information to the end user regarding how to install or remove this RF module in the user’s manual of the end product which integrates this module. The end user manual shall include all required regulatory information/warning as show in this manual.
Limited module procedures
The device is a limited module approval.
Trace antenna designs
Not applicable, The module has its own antenna, and doesn’t need a host sprinted board micro strip trace antenna etc
RF exposure considerations
The device has been evaluated to meet general RF exposure requirement. The device can be used in portable exposure condition without restriction; and if RF exposure statement or module layout is changed, then the host product manufacturer required to take responsibility of the module through a change in FCC ID or new application The FCC ID of the module cannot be used on the final product In these circumstances, the host manufacturer will be responsible for re-evaluating the end product (including the transmitter) and obtaining a separate FCC authorization
Portable host information:
Product Name: 2.4G MIDI IN/OUT Wireless Virtual Cable
Model Name: MIDI MATE, MIDI MATE OUT, MIDI MATE IN, MIDI CAPTAIN
Antennas
Antenna Specification are as follows:
Type of antenna: PCB Antenna
Gain of antenna: 0dBi Max.
This device is intended only for host manufacturers under the following conditions: The transmitter module may not be co-located with any other transmitter or antenna;
The module shall be only used with the internal antenna(s) that has been originally tested and certified with this module. The antenna must be either permanently attached or employ a “unique” antenna coupler
As long as the conditions above are met, further transmitter test will not be required However, the host manufacturer 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)
Label and compliance information
Host product manufacturers need to provide a physical or e-label stating ” Contains FCC ID: 2BFBY-MIDIMATE”with their finished product
Information on test modes and additional testing requirements
Host manufacturer must perform test of radiated & conducted emission and spurious emission, e.t.c according to the actual test modes for a stand-alone modular transmitter in a host, as well as for multiple simultaneously transmitting modules or other transmitters in a host product.
Only when all the test results of test modes comply with FCC requirements, then the end product can be sold legally.
Additional testing, Part 15 Subpart B disclaimer
The modular transmitter is only FCC authorized for FCC Part 15 Subpart C 15.249 & 15.207 &15.209 and that the host product manufacturer is responsible for compliance to any other FCC rules that apply to the host not covered by the modular transmitter grant of certification.
If the grantee markets their product as being Part 15 Subpart B compliant (when it also contains unintentional-radiator digital circuit), then the grantee shall provide a notice stating that the final host product still requires Part 15 Subpart B compliance testing with the modular transmitter installed
Module installation
The wireless module is installed in the host product by the factory operator during the production process.
After assembly, the wireless module is built-in by welding in the host product, which is not removable and will not be used alone, and does not require additional operation by users and other personnel.
The procedure and installation position of wireless module production and assembly are shown as below:

- 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:
- This device may not cause harmful interference, and
- this device must accept any interference received, including interference that may cause undesired operation

IMPORTANT NOTES
Co-location warning:
This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter
OEM integration instructions:
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 The module shall be only used with the external antenna(s)that has been originally tested and certified with this module As long as the 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.).
Validity of using the module certification:
In the event that these conditions cannot be met (for example certain laptop configurations or co-location with another transmitter),then the FCC authorization for this module in combination with the host equipment is no longer considered valid and the FCC ID of the module cannot 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 Transmitter Module FCC ID: 2BFBY-MIDIMATE”
Information that must be placed in the end user manual:
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 user’s manual of the end product which integrates this module The end user manual shall include all required regulatory information/warning as show in this manual.
