    • An electronic timepiece having a liquid crystal display for displaying a time standard signal which is supplied thereto is provided. A light source for lighting the liquid crystal display is disposed proximate thereto. A time correcting circuit including manually operated switches is coupled to an electronic divider circuit which supplies the timing signal to the display to correct the displayed digits of time counted thereby. The time correcting circuit is provided with a safety switch which in a first position allows a correction switch to effect correction of a displayed digit and in a second position protects against inadvertent time correction and allows the lighting of the light source to make the digital display readable in the darkness.
    • 提供一种具有用于显示提供给其的时间标准信号的液晶显示器的电子钟表。 用于点亮液晶显示器的光源设置在其附近。 包括手动操作的开关的时间校正电路耦合到电子分频器电路,该电子分频器电路将定时信号提供给显示器,以校正由此显示的时间的显示位数。 时间校正电路设置有安全开关,其在第一位置允许校正开关实现显示的数字的校正,并且在第二位置中防止无意的时间校正,并且允许光源的点亮使数字显示器可读 在黑暗中
