    • A fixed subscriber unit includes a voltage measuring unit which acquires a DC input voltage value to be applied to a power circuit, and a comparator/judging unit which compares a preset DC voltage with the DC voltage measurement and judges whether the power circuit is driven by the DC voltage from an AC/DC adaptor or by the DC voltage supplied from a charge battery. When the power circuit is driven by the charge battery, the available operation time of the fixed subscriber unit is calculated by a calculation unit from the DC voltage measurement. The information thus obtained on the driving power state and/or the available operation time are aurally or visually notified to the user by a notification unit. The user thus can select an appropriate method of using the fixed subscriber unit according to the prevailing situation.
    • 固定用户单元包括:电压测量单元,其获取要施加到电源电路的DC输入电压值;以及比较器/判断单元,其将预设的DC电压与DC电压测量进行比较,并判断电源电路是由 来自AC / DC适配器的直流电压或由充电电池提供的直流电压。 当电源电路由充电电池驱动时,通过计算单元从直流电压测量计算出固定用户单元的可用操作时间。 通过通知单元将由此获得的关于驱动功率状态和/或可用操作时间的信息听觉地或视觉地通知给用户。 因此,用户可以根据当前情况选择使用固定用户单元的适当方法。
