A system for remotely controlling operation of a device has a transmitter unit and a receiving unit. The transmitter unit has a circuit (2) which produces a control signal when the system is being operated, and transmitter circuit (6, 10, 11) for repeatedly transmitting the control signal. The receiver unit has a receiving circuit (20, 2, 22) which receives the transmitted signal, and operation control circuit (24-30) responsive to the received signal for initiating operation of the device and maintaining operation of the device provided the transmitted control signal continues to be received. |
