ABSTRACT:
A remote control system for operating an electrical apparatus has a transmitter for transmitting binary coded commands to a receiver which in turn controls the operation of the electrical apparatus. The apparatus is activated by the receiver in accordance with the received command. Whenever an alteration in the operating condition of the transmitter occurs, a recognition signal is automatically generated and transmitted by the transmitter to signify to the receiver that such an alteration has occurred. The transmitter is equipped to automatically switch off only if it has transmitted the recognition command at least once.
