该时钟以24小时制显示时间，并可显示2000年至2049年之间的任何日期及星期，日期与时间经按键可相互切换，可输入8个闹钟时间设置，每个闹钟设置包括响铃的时间（小时与分钟）、对工作日有效还是对周末有效的标志，以及本项设置是否启用的标志等三部分。这8个闹钟设置均保存在EEPROM中，即使掉电也不用重新输入。-The 24-hour clock to display time, and shows from 2000 to 2049 and any date between the weeks, the date and time as may be mutually switch button, enter the eight alarm time settings, each set including the ringing of an alarm clock Duration (hours and minutes), the effective working days or weekends effective road signs, as well as whether or not to enable this setting, such as a symbol of three parts. This 8 alarm settings are stored in EEPROM, even brown-out do not have to re-enter.
