works only partially

The assessment covers the Somer transmitter mini 4050-2 commands. He was to replace our existing and functioning but damaged transmitter.
Two different commands to perform the hand-held transmitter. In our case, the existing station is programmed to open an electronic roller door of an underground garage with a corresponding traffic light: a command opens the gate from the inside, traffic lights inside to green light, outside on the red light, the other command opens the gate from the outside with corresponding reverse traffic lights.
As the program is to handle, has stated on several occasions on the Internet, eg Youtube with a video tutorial. In my case, it worked only partially.
A push-button of the remote control could easily be "train", the second pushbutton that was not possible.
Thus, the new hand-held transmitter can be used at the time only for a command.
Maybe I'll find another way, the transmitter completely "to learn", possibly directly to the receiver.
Three Star Rating I think therefore still appropriate.
