Push the remote button, LED indicator on the receiver board will flash then come off. After 3 seconds, the LED indicator will be on again, learning successfully. Learning the Code: (Toggle) Press the learning key on the receiver twice time, it comes into toggle setting mode. Wait for a moment, the LED will be off , it comes into learning state. Press the remote button, LED indicator on the receiver board will flash then come off. After 3 seconds, the LED indicator will be on again, learning successfully. Learning the Code:( Latching) Note: When you choose for latching mode, in order to learn more remote control, you need to learn two different button, the first time learning is for ON, the second time learning for OFF. For example: Button A = ON, Button B = OFF Press the learning key on the receiver triple time, it comes into latching mode . Wait for a moment, the LED indicator on the receiver board will flash then come off. Press the remote button A. LED flash for 5 times. Press the remote button B. LED flash for 5 times After 3 seconds, the LED indicator will be on again, learning successfully. A = ON, B = OFF. NOTE: 1.The system can store for 25 pcs of remotes , if the remote get more than 25 pcs , the initial remote control will be lost . 2.
