Multi-functional and user-friendly design, simple and fast to use. This smart copy remote control is compatible with electric door remotes, telescopic door remotes, and garage door remotes. Clearing: Press the top two buttons simultaneously. The LED indicator flashes three times, then release the right button (keep holding the left). Press the right button three consecutive times. The indicator light will flash. Then press any button; if the light remains off, the clear function is complete. Copying: Press the corresponding button on the old remote and this remote at the same time. The LED will flash quickly twice, then slowly three times, and then stay lit continuously. This completes the copying process for that button. Repeat the same steps for the remaining three buttons.
