IMPORTANT NOTE:
This module is intended for OEM integrator only and the OEM integrators and instructed to ensure that the end user has no manual instructions to remove or install the device. The OEM integrator is still responsible for the FCC compliance requirement of the end product, which integrates this module. Integration is typically strictly restricted to Grantee himself or dedicated OEM integrators under control of the Grantee. In the event that these conditions can not be met (for example certain laptop configurations or co-location with another transmitter. then the FCC authorization is no longer considered valid and the FCC ID can not be used on the final product. In these circumstances, the OEM integrator will be responsible for re-evaluating the end product (including the transmitter) and obtaining a separate FCC authorization. The module will be responsible to satisfy SAR/RF Exposure requirements, when the module integrated into any (portable, mobile, fixed) host device. The module must in the end-product be installed in such manner that the authorized antennas can be used, any change of the antenna will void the certification. LABEL OF THE END PRODUCT:
The final end product must be labelled in a visible area with the following "Contains TX FCC ID:
2ALGY-NRF52840 part 15.19 statement is required to be available in the users manual: This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. is smaller than 8x10cm, then additional FCC If the size of the end product
