Please confirm two things (First, Frequency; Second, Chip Code(Encoder integrated circuit)before you buy it. It's very very important. Don't ignore them.

Don't simple think the frequency is same then it can be copied. It's not true.

The method of confirming the crystal frequency and chip model is shown in the figure

Step 1 : Clear codes

Press the A button and B button at the same time, after the LED indicator light flashes three times, loosen any one of the buttons while the other is kept pressing, then push the released button three times, the LED indicator will enter into the fast flashing status. At this time all the memory data is cleared, the cleaned remote control will not have lighting LED indicator no matter which button you press.

Step 2: Copy method

One hand keeps the original remote controller, while another keeps the copy remote control, the two remote controls should be placed as closely as possible (the ideal situation is to put the two remote controls on the desktop side by side with zero distance), respectively press down the copy button, when the LED indicator light flashes quickly after three flashes, this copy is successful, other key operating methods are the same. Some remote control has a smaller transmitting power, so the original remote control should be placed back to back the copy remote control to be operated. For the presence of noise, it should avoid interference to operate, If the copy is not successful, it should recopy after clearing code.

Resume/Recovery Code

If you clear code of duplicating remote control incautiously, you can press Button C and Button D at the same time, the LED Indicator Light flash fast. It means that the code of duplicating remote control is resumed.
