About the sensitivity adjustment: Press the LEARN+MODE ERSET buttons simultaneously, and the three lights flash together, meaning the sensitivity adjustment mode has been entered. Place the induction key at the sensing distance you need. After the sensitivity setting is successful, the farther the key is from the door, the farther the sensing distance will be. The closer it is placed, the closer the sensing distance will be. Then turn the sensitivity dial to receive the sensing distance you placed (the resistance to turning the sensitivity button will be relatively large to prevent accidental touch. If it is difficult to turn, please use tools to turn it). When it is turned to a suitable position, the three lights will flash six times at an interval of 0.5 seconds, which means that the distance acceptance has been completed. Then short press the MODE button to exit and the sensitivity setting is completed. Introducing the ultimate solution for busy pet owners - the Smart Pet Sensing Door.
