Abstract

A system for remotely controlling electrical devices as in the starting of automobiles and the like employing a transceiver, a receiver-transmitter and an actuating solenoid. The transceiver includes circuitry adapted to transmit selected radio frequency signals for performing selected functions during starting of the automobile. The receiver-transmitter includes circuitry adapted to transmit a signal to the transceiver upon receipt of a first check range signal from the transceiver, energize the auto ignition circuit and energize the auto starter upon receipt of a second signal from the transceiver, and energize the actuating solenoid upon receipt of a third signal. The solenoid is adapted to actuate the fuel linkage upon being energized. The receivertransmitter circuit is further adapted to limit the running time of the engine upon starting, transmit an intermittent signal to the transceiver during initial engine running, and stop the engine upon opening a door of the auto during the initial engine running period.
