(1)this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. If power exceeds the limit and the distance( Over 20cm distance in actual use between the device and user) is compliant with the requirement. Sichuan AI-Link Technology Co., Ltd. page 7 of 9 Notice to OEM integrator If the FCC ID 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. The end product shall haves the words Contains Transmitter Module FCC ID: 2AOKI-WFM68AUWF1. The device must be professionally installed. The intended use is generally not for the general public. It is generally for industry/commercial use. The connector is within the transmitter enclosure and can only be accessed by disassembly of the transmitter that is not normally required. The user has no access to the connector. Installation must be controlled. Installation requires special training. Any company of the host device which installs this modular with unlimited modular approval should perform the test of radiated & conducted emission and spurious emission, etc. according to FCC part 15C: 15.247 and 15.407and 15.209

& 15.207, 15B Class B requirement, only if the tests result comply with FCC part 15C: 15.247 and 15.407 and 15.209 &

15.207, 15B Class B requirement, then the host can be sole legally When the module is installed inside another device, the user manual of the hose contain below warning statement:

1) This device may not cause harmful interference. 2) This device must accept any interference received, including interference that may cause undesired operation. CIC Radiation Exposure Statement Sichuan AI-Link Technology Co., Ltd. page 8 of 9 Sichuan AI-Link Technology Co., Ltd. page 9 of 9
