Rule Part 15.19(a)(3): 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. b. Rule Part 15.21: The users manual or instruction manual for an intentional or unintentional radiator shall caution the user that changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. 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. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: —Reorient or relocate the receiving antenna. —Increase the separation between the equipment and receiver. —Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. —Consult the dealer or an experienced radio/TV technician for help. — This equipment complies with the FCC RF radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with a minimum distance of 20cm between the radiator and any part of your body. Thank you

July 11, 2022 Federal Communications Commission Equipment Authorization Branch 7435 Oakland Mills Road Columbia, MD 21046 ORIGINAL TEST REPORTS COVER LETTER FCC ID : 2A7KGGK-WL3B001 The module installed into host platform mentioned above is electronically and mechanically identical to the original certified module(2A7KGFSC-BT630 and 2A7KG-WIZFI360PA). The Original FCC testing on module under FCC ID: 2A7KGGK-WL3B001 The current host platform under application uses an antenna of the same type is installed inside the host platform enclosure. The physical restraints introduced by the host platform should have resulted in equal or lower level of radiated emission. Therefore, additional Radiated emission testing is not necessary. Software security remains unchanged from the original application. Except for the change above, the design, hardware and implementation are exactly same with original. If you have any questions regarding this application, please feel free to contact me. 1. The wireless module in the 2A7KGGK-WL3B001 has the same electrical, circuit, and antenna gain as 2A7KGFSC-BT630 and 2A7KG-WIZFI360PA 2. The 2A7KGGK-WL3B001 equipment was equipped with 2A7KGFSC-BT630 and 2A7KG- WIZFI360PA, and only radiation tests were conducted.
