(OEM) Integrator has to assure compliance of the entire end-product incl. the integrated RF Module. For 15 B (15.107 and if applicable 15.107) 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.
