Abstract
To provide a remote control by means of coded signals, a portable transmitter case (3) is used comprising, on the one hand, a keyboard (5) with keys (6) for directly forming the coded signal on said case and, on the other hand, means for recording this coded signal, for storing it in the memory for a time t.sub.o at the end of which it is automatically erased, as well as a control button (10) ensuring the instantaneous transmission of the signal thus previously stored in the memory.
