Abstract (en)
[origin: EP0212050A2] In the coding process for operating a door lock, the coding signal emitted by a transmitter can be entered in a memory, so that, during subsequent opening operations, it can be compared with the particular coding signal then emitted. Since the door-closing system in this way learns the coding signal sent by the transmitter, it is unnecessary, when the transmitter or receiver is exchanged, always to use modules synchronised with one another. <IMAGE>
