1. Clearing method: Press and hold the A key and the B key at the same time, the LED indicator will flash three times. Release the pressed B key, and the A key will not be loosened. Click the released B key three times, and the LED indicator will enter a fast flashing state. At this time, all the data in the memory will be cleared. After the data is cleared, the LED indicator of the remote control will not light up no matter which key is pressed.

2. Copying method: One is to hold the original remote control, the other is to hold the copy remote control. The two remote controls should be as close as possible ideally, the two remote controls should be placed close to each other on the desktop at zero distance. Press the buttons required for copying respectively. The LED indicator lights flash quickly for three times and then flash quickly. Copying is successful. The operation method of other buttons is the same. Some remote controllers have low transmission power, so the original remote controller and the copy remote controller should be operated back-to-back to copy each other. If there is interference in some operating environments, the interference operation should be avoided. If the copy is not easy, the copy should be repeated after the code is cleared. Especially important: the remote control on your hand must work normally and have the same frequency of 433MHZ as our remote control
