Reference schematic diagram 1. The MAIN is the WIFI-2.4G&5G antenna interface, and the AUX is the BT antenna interface, which needs to be controlled according to 50 impedance. 2. Ensure that the GND PIN near the antenna port is properly grounded (direct copper laying is recommended). 3. In order to facilitate the adjustment of RF performance, a -type matching circuit should be reserved between RF_ANT and the antenna. The circuit should be placed close to the antenna and the specifications should be selected according to the actual situation. When both the antenna and RF wiring have good performance, attach 0 through, and the NC of the devices on both sides is not attached. When the impedance of the antenna is mismatched, it can be matched and debuggable through this circuit. 4.RF wiring should be as short as possible, and avoid right and acute Angle wiring. 5. Try to reserve the UART0&UART1 cable design on the motherboard to facilitate RF performance testing and debugging. 11.

-3 19 SKI.WB800D.3 FCC Statement 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 inaccordance 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 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. Any changes or modifications not expressly approved by the party responsible for compliance could void the users authority to operate the 20 equipment. SKI.WB800D.3 Please notice that if the FCC identification number is not visible when the module is installed inside another device, then the outside of the device into which the module is installed must also display a label referring to the enclosed module. This exterior label can use wording such as the following:

Contains FCC ID:2AL3T-WB800D any similar wording that expresses the same meaning may be used. This equipment complies with FCC 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 & your body. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. The module is limited to OEM installation ONLY. The OEM integrator is responsible for ensuring that the end-user has no manual instruction to remove or install module. The module is limited to installation in mobile application. A separate approval is required for all other operating configurations, including portable configurations with respect to Part 2.1093 and difference antenna configurations. There is requirement that the grantee provide guidance to the host manufacturer for compliance with Part 15B requirements. The module complies with FCC Part 15.247 / Part 15.407 and apply for Single module approval. 21 SKI.WB800D.3 Instructions for use SKI.WB800D.3 is a Wi-Fi module used in commercial display, and the first batch of home appliances are IFPD and TV . The module is implemented by AIC8800D Wi-Fi IC, which is provided to customers in the form of modules. The hardware and software architecture based on the module can realize the networking and connect to the Wi-Fi router or Bluetooth equipment. The module meets the requirements of standard protocol IEEE 802.11 b/g/n/ax and Bluetooth 5.2 with BLE and it is connected to Main Soc by USB interface. The power management, power amplifier and low-noise amplifier are integrated in the AIC8800D chip of the module which provide a low power consumption for users. 22
