Try to press this button, the LED light will light up, indicating that you have successfully copied. Perform the same steps for the other buttons.Recovery function.If you accidentally delete a useful code, you can press the 3rd and 4th buttons at the same time until the LED light flashes quickly 3 times, and then the recovery is successfulWe generally do not recommend copying rolling code chips, because there are many uncertainties in copying rolling code chips. When copying the rolling code remote control chip, it is impossible to judge whether the original remote control chip is an encryption chip. Therefore, we recommend copying the rolling code remote control.1The latest IC programming procedures to prevent accidental deletion of codes. 2Suitable for 4channel wireless remote control of cars, car sunroofs, garage doors, gates, alarm systems, heating systems, home automation, etc. 3This is a fixed frequency remote cloner 433MHz, used to copy 99.99% common fixed and learning code remote control. 4The device has a good transmission distance, flexible functions and stable signal. 5Easy to use, the 4channel remote control system allows you to control your gadgets, cars, homes and garages. 6This is an attractive and lightweight remote control, small enough to hold a key chain, so it's not bulky at all, and it's easy to carry when going out.
