What should I do when my device fails to connect to the network? Answer: 1. Please check whether your device is powered on and turned on. 2. Whether the phone and device are in the same Wi-Fi network 3. If the network is normal, but the device network connection still fails, check whether the router is overloaded. You can disable a device’s Wi-Fi feature to reserve the channel for resource reallocation. 4. Please confirm whether the entered router password is correct, pay attention to whether there is a Wi-Fi account or password before and after Space and capitalization issues. 5. Please check whether the connected Wi-Fi is a 2.4G network If there are other questions, please go to the APP and select "Me"-->"FAQ& Feedback" to find the corresponding problem solution.

Operation is subject to the following two conditions: (1) this device may not cause harmful interference, (2) this device must accept any interference received, including interference that may cause undesired operation . The manufacturer is not responsible for any radio or tv interference caused by unauthorized modifications or change to this equipment. Such modifications or change 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 interferencewill not occur in a particular installation. If this equipment doescause 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. RF warning statement: To maintain compliance with FCC's RF exposure guidelines, this equipment should be installed and operated with a minimum distance of 20cm between the radiator and your body.
