Conditions for re-use of modular certification Any modifications made to the module will void the Grant of Certification, this module is limited to OEM installation only and must not be sold to end-users, end-user has no manual instructions to remove or install the device, only software or operating procedure shall be placed in the end-user operating manual of final products. Additional testing and certification may be necessary when multiple modules are used. To ensure compliance with all non-transmitter functions the host manufacturer is responsible for ensuring compliance with the module(s) installed and fully operational. For example, if a host was previously authorized as an unintentional radiator under the Supplier’s Declaration of Conformity procedure without a transmitter-certified module and a module is added, the host manufacturer is responsible for ensuring that after the module is installed and operational the host continues to be compliant with the Part 15B unintentional radiator requirements. Since this may depend on the details of how the module is integrated with the host, (StreamUnlimited Engineering GmbH) will provide guidance to the host manufacturer for compliance with the Part 15B requirements. If any doubt about product compliance due to integration, StreamUnlimited provide via its customer portal software a documentation to re-check compliance.(see Stream1832AE Certification Guidelines.pdf) The modular certifications may be re-used on product level under following conditions: 1. Recommended antennas specifications are followed (see Stream1832AE_Generic_Antenna_Specification.pdf ) 2. The WiFi output power configurations which are stored in “rgpower_XX.bin” remain unchanged 3. The Bluetooth output power which is hard-coded in firmware to 6dB remains unchanged 4. Product labelling requirements are met 5. Instructions for use requirements are met For FCC Compliance, please refer to KDB Publication 996369 D04 for up-to-date information about module integration. Additional notes: Ad 1): StreamUnlimited provide specific PowerTable binaries for “CE” “FCC” and “MIC” configurations. Region is selected during end-product configuration prior to product encasing. In the same step, also the country which the product is intended for should be configured. In the case that no region is configured, the binary for “CE” will be…
