说明书

使用说明:

一、首先开机显示“00-00-00”为“时-分-秒”时间显示。

二、按“调整”键进入调整界面“1-000000”为“代号-时分秒”。“S”，“M”，“H”为时、分、秒的调整，调整结束后按“确认”键进入下一个的调整“2-000000”为定时开机时间的调整，调整方法同上，依次调整“3-定时关机时间”、“4-闹铃时间”、“5-定时时间”、“6-年月日”。

三、调整结束后显示正常时间，按键“定时”进入定时界面，根据调整的时间开始定时，同时看“正反”计时键按下为倒计时，不按为正计时。到时间响铃，按键“返回”回到主界面。

四、正常显示时间的时候按键“正反”计时键切换到年月日的显示。按住“返回”键3秒可以软关机，开机亦如此。
