HM-BT2204 V1.0 (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).
HM-BT2204 V1.0 (2) this device must accept any interference received, including interference that may cause undesired operation." NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation.
HM-BT2204 V1.0 Changes or modifications to this unit not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. Module statement The single-modular transmitter is a self-contained, physically delineated, component for which compliance can be demonstrated independent of the host operating conditions, and which complies with all eight requirements of §15.212(a)(1) as summarized below.
