Working properly, but it would be better to have a notice with. This would avoid wasting time on the Internet to find instructions. To clear the codes press the 2 key up. To save press the desired button hold down, take the remote control to copy and paste this one is by pressing the button to copy. When the code is registered the red LED blinks continuously. It is done. Please note you may need to walk on the remote control while the box of the one you want to copy because you really the 2 antennas are very very close. Each button can register a different code. I have a colleague who has found the staff friendly product and has a buy on a Chinese site, much cheaper, the appearance is the same but against the procedure is different for registration, more complicated, and the more it records only 2 frequency (O / F) its remote control while the latter has no problem to do so. Now I can open and close the garage :) Just kidding .... I erased
