The final host product still requires Part 15 Subpart B compliance testing with the modular transmitter installed when contains digital circuity.
FCC Statements
(OEM) Integrator has to assure compliance of the entire end-product incl. the integrated RF Module. For 15 B (§15.107 and if applicable §15.109) compliance, the host manufacturer is required to show compliance with 15 while the module is installed and operating.
Furthermore the module should be transmitting and the evaluation should confirm that the module’s intentional emissions (15C) are compliant (fundamental / out-of-band). Finally the integrator has to apply the appropriate equipment authorization (e.g. Verification) for the new host device per definition in §15.101.
Integrator is reminded to assure that these installation instructions will not be made available to the end-user of the final host device.
The final host device, into which this RF Module is integrated has to be labeled with an auxiliary label stating the FCC ID of the RF Module, such as “Contains FCC ID: 2ARXB-051A”.
