Abstract: A car remote control system utilizing a signal in the form of electromagnetic wave or infrared ray called ‘keyless entry’. When receiving a predetermined wake-up signal, an MPU is once operated even when the received input signal is a noise signal to perform only judging operation of whether or not the input signal is normal. Only when judging that the input signal is a normal wake-up signal, the MPU controllably causes an electronic circuit to be shifted to a usual operation mode. When judging that the input signal is the noise signal prior to full input of the tuner signal, the MPU immediately shifts to a sleep mode. Thereby current consumption of an electronic control circuit can be suppressed.
