Abstract Apparatus for receiving remote control signals which comprise an alternating sequence of two chronologically successive pulses, the first pulse having a first prede- termined frequency and the second pulse having a second fre- quency manually selected from a predetermined number of fre- quencies, such of the predetermined number of frequencies representing a command to be carried out The receiver com- prises a signal detector, a signal amplifier and a circuit for decoding the remote control signal into a group signal dependent on the first frequency and a command signal da- pendant on the second frequency A controllable gate is provided for gating the command signal from the decoding circuit to a command signal register having a command sig- nal input for each of the commands, and an input for block- ing each command signal output. Means coupled to the com- mand signal outputs implement the commands. A circuit re- sponsive to the group signal controls the gate, while a circuit responsive to receipt of a command signal in the register causes the remaining command signal inputs to be locked. - 1 -
