Abstract

PURPOSE: To inform users of the expiration of a battery only in the case when users need without exerting influence upon the display of time, by generating the informing sounds of the expiration of the battery when switching an alarm set switch OFF from ON.
CONSTITUTION: When set time is up under a condition that an alarm set switch 20 is made and a standard 18 is closed, alarm sounds manufactured by synthesizing 22 the output of a frequency divider 4 are generated from a speaker 34. When the voltage of a battery 54 beforehand drops, an AND gate 38 is brought to an opening condition by the output Q of a flip-flop 58. When the switch 20 is put to an opening condition from a closing condition under this condition, the alarm sounds stop while a 4th incremental counter 42 counting signals in 4Hz puts out pulses after one second, the output of a flip-flop 46 is made to be a H level and signals in 2048Hz from the frequency divider 4 are generated 34 as battery life informing sounds through gates 36, 38, 30.
