ABSTRACT:
A timer device for controlling the ON/OFF of a power source generates a long delay from the time when the power source is turned on to the time when the power source timer function thereof is validated. When the power source is turned off and then turned on at a short interval, the device is initialized and prevents equipment incorporating the device from being used over a long period of time. The device, therefore, obviates the illicit use of the equipment.
