If the red light flashes, this indicates a low battery or a system error. Please follow the troubleshooting steps outlined below:Sensor error: The device might not be correctly positioned on the food container. Adjust its position and attempt the process again. If the issue remains, proceed to #2.Sensor obstruction: The sensors may be blocked by substances like grease, dirt, etc. Gently clean the sensors with a damp cloth and retry. If the issue remains, proceed to #3.Sensor non-response: The device appears to be unable to detect a response from the sensor reflectors on the lid. This could result from lid deformation, potentially caused by exposure to high heat. Release the locking flaps to relieve any tension in the lid, then reposition the device on the lid. Ensure the sensors align with the lid’s sensor reflectors and initiate the cycle again. Remember to secure the flaps after the process. If the issue remains, advance to #4.Power Deficiency: Charge the device with the provided USB-C cable. The device is inoperable during charging. A green light will signal when the device is fully charged. If the issue persists, refer to #5.Your device seems to be encountering an unknown problem.
