perfectly compatible with my old remote control HS (M) 2/4 868.3 Mhz Note however that the size of the box: It is formatted door keys ... The case opening design is zero ... It takes strong nails, but as the battery is in place, we can make him learn the code immediately from the original remote, it's easy and Ultra fast. If you do not have a remote control, it will refer to engine leaflet (P button (or Tubauto Hormann)) or possibly the little red button on the little box to the transmitter if it is not integrated into the motor (in my case). There is also a small reset button "factory" on the electronic board of the remote control. If it loses its engine code, it must first initialize the "factory", then let him learn the engine code from another remote ... if you made from the P button, a new code is generated, so, all other remote controls will be initialized and then plant it will make them learn the engine code from the remote control that has already learned.
