Is this approach consistent with FCC rules and prior approvals?

Yes, this approach aligns with FCC labeling requirements under Title 47 Code of Federal Regulations Section 2 point 925, as well as long-standing FCC and TCB practice. It is also consistent with prior L3H approvals for this same product configuration. When a transmitter is tested and approved as part of the host, no separate FCC ID labeling is needed. When the host depends on a transmitter approved elsewhere, the FCC ID must be disclosed.
