The traffic lights of electric mattresses don't need to be on all the time. The red light is usually the key to open and close the electric mattress, while the green light is used to adjust different temperature gears. When using the electric mattress, turn on the red light and turn off the green light to ensure one's safety. If the red light is off or the green light is on all the time, it may need to be repaired. At the same time, we should avoid placing sharp objects, articles with heavy moisture on the electric mattress and moving frequently beside the bed to prevent electric shock or damage to the electric mattress. After long-term use, check the condition of the wire plug, and replace the patch panel in time if it is aging or discolored.
