Additional testing, Part 15 Subpart B disclaimer

The modular transmitter is only FCC authorized for FCC Part 15 Subpart C 15.247 & 15.207 & 15.209 & 15.205 and FCC Part 15 Subpart E 15.407 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 circuity), 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.

As shown in the diagram, the module is only controlled and powered by ABC representing a three way USB circuit. Normally, it can be replaced with a separate cable. D and E represent the exit of the antenna. But for the convenience of frequency setting and testing, it is fixed on the public board. That is to say, the module can work independently from the public board, and the blue box in the table is suspended and not working. This cable method is the final installation method of the module.
