Description: Step 1 Clearing method:  Press the "A" button and the "B" button at the same time, the LED indicator flashes three times, release the pressed "B" button, the "A" button is not loose, click the released "B" button three times, LED indication The light enters the fast flashing state. At this time, the memory data is completely cleared. After the data is cleared, the LED indicator is not lit no matter which button is pressed.   Step 2 Copy the method:     One hand holds the original remote control, the other holds the remote control, and the two remotes are as close as possible. (ideally, the two remotes are placed on the desktop with the zero distance on the side.) Press the desired button. The LED indicator flashes rapidly after three flashes, and the copy is successful. The other buttons operate in the same way. Some remote controllers have a small transmitting power, and they should be back-to-back operated with the original remote control and the remote control. Some operating environments have interference, and should avoid the interference operation. If the copying is not good, copy it again after clearing the code. (It's especially important: the remote control on your hand must work properly and be the same frequency as our remote control)   New copy remote control features:     Four buttons can be used to copy four different types of chips, that is, one remote can operate four different types of facilities. The frequency ranges from 270MHz to 434MHZ and more than ten frequency points. Copying data is faster, it is not easy to lose code, and the distance is far.
