1. Radio remote control that allows you to copy (clone) the codes of other remote controls. It can copy almost all remote controls operating at a frequency of 433.92 Mhz with a fixed code. The remote control is made carefully and looks good. 4 buttons - under each of them there can be a different control device. Designed for simple radio communication systems, such as roller shutters, remote control relay, remote quad shooting, entrance gates. 2. It can handle the control of entrance gates, garage doors, alarm systems, lighting, etc. Copying a code from another remote control is very simple - just enter both remote controls and press the button you want to copy. After making a copy, you can control the corresponding device with both the original remote control and the clone. By pressing buttons A and B, the code memory is erased, and buttons C and D restore the deleted codes.

Hold them together until the LED on the remote control starts to flash quickly and then lights up continuously, which means that the code has been memorized, release the button. Press again, the code will be sent and the LED will start to flash, which means that the copying was successful. Do the same with the other buttons. 6. Reset function.
