Abstract
A fail safe circuit is provided in the receiver of a multi-signal transmission system which includes a transmitter and a receiver each of which incorporates a resettable power supply. The fail safe circuit comprises a signal check circuit which detects whether a check bit has been received or not and a power supply reset circuit which, when the check bit is not present, once shuts off and then resets both the power supplies incorporated in the receiver and the transmitter in order to initialize the transmitter and the receiver.
