计价表使用说明
（1）S1按键的功能
在出租车不走的时候，按下S1，可以实现数据的分屏显示；车在行走的时候只有总金额和单价显示屏在显示，当到达目的地的时候，客户要求查看总的里程的时候，就可以按下S1 切换到里程和单价显示屏，供客户查询。
（2）S2按键的功能
在按下S1按键之后，若接着按下S2键则进行单价调整（默认为调整白天单价），当接着按下S1时，则进行晚上单价调，再次按下S1可进行中途等待单价调整。当单价调整结束后，可以通过过按下S2按键进行时间调整，默认为调整时，接着按下S1可进行调整分，分调整后再接下S1可进行秒调整。当时调整完成后，若接着按下S2则又可进行单价调整。
（3）S3按键的功能
在显示金额及单价时，若按下S3键则显示路程和单价，再次按下S3，可返回显示金额及单价。
（4）S4按键的功能
在按下S1按键之后，若接着按下S4按键，则进行设定默认晚上单价，并启动计价器，若没有按下S4则可设定默认单价（白天），并启动计价器。当设定默认晚上单价结束后，再次接下S4按键，则可设定默认中途等待单价，并启动计价器。当设定默认中途等待单价后，若还按一次S4，则返回系统时间的显示。
数据的分屏的显示是通过按键S1 来实现切换的，如图7 所示。
在出租车不走的时候，按下S1，可以实现数据的分屏显示；车在行走的时候只有总金额和单价显示屏在显示，当到达目的地的时候，客户要求查看总的里程的时候，就可以按下S1 切换到里程和单价显示屏，供客户查询。显示电路的电路原理图如图8所示。
