Abstract
In an electronic timepiece including a circuit for setting a voltage level at which alarm is given to indicate the termination of battery lifetime, driving voltage level of a time display device of the timepiece, frequency dividing ratio by which frequency of the timepiece is determined, or the like, a selecting circuit is provided for supplying different voltage level- or frequency dividing ratio-adjusting signals. The voltage level or frequency dividing ratio is precedently set by the different adjusting signals supplied from the selecting circuit and then is fixed by means of a voltage level- or frequency dividing ratio-setting signal supplied from outside selecting terminals.
Claims8
Electronic timepiece comprising:
- a level setting circuit whose level is set by a level setting signal supplied from a plurality of outside selecting terminals,
- a selecting circuit for supplying different level adjusting signals, and
- a switching circuit for switching said level setting signal and said level adjusting signals to selectively supply either of said signals to said level setting circuit, wherein a desired level is set by said level adjusting signals and then is fixedly set by selecting said outside selecting terminals.
