Abstract
The two channel remote control system activates the engine of an automobile and also activates predetermined accessories in the automobile such as a heater or an air-conditioner. A first paging system is activated by telephonic inputs originating from a user. This first paging system generates a start remote command. A first paging receiver is mounted in the automobile and receives the start remote paging command. The first paging receiver is acoustically or optically coupled to an audio receiver which is mounted in the automobile. The audio receiver, receiving the start remote command, triggers a controller circuit, a timing circuit, an ignition control circuit and a start motor circuit. The timing circuit generates periodic ignition trigger signals for the ignition control circuit. These trigger signals are generated a predetermined number of times. The timing circuit generates an ignition OFF signal after a predetermined period after receipt of the start remote command. The timing circuit issues another trigger signal to the start motor circuit. The start motor circuit then periodically activates the starter motor driving the engine in the automobile based upon a periodic starte…
