Abstract

PURPOSE:To display the moment of requlation and prevent malfunction, by operating the battery life display meachanism by manipulating the external regulator switch. CONSTITUTION:When an external regulator swich 9 is set ON, AND gate 11 inputs 1 Hz of clock pulse into preset part 8 to set to content of the frequency dividing stage. At this time, a signal 1 is outputted simultaneously from upper end (a) of pulldown resistance 10 to part (b) of OR gate 3, and this signal 1 takes NAND with clock pulse at NAND gate 4 to be displayed in a battery life display circuit BLD. The original purpose of BLD, namely, detection of battery life, is normally working because a circuit is composed with OR gate 3. Thus, when an external switch is in regulation mode, BLD is operated to display the progress of regulation, so that malfunction may be prevented.
