Press key to enter Run ModeDisplay will show symbol above current time8th day schedule will be implemented on Thursday and run for 2days and then timer will revert back to normal programs.NOTE:If Sel.key is held down, it will scroll rapidly to 99 and back to 01To review the implementation scheduled, press key once.Display shows day of implementation and number of days holiday pro-gram will be active.Press key.To delete the implementation scheduled, press key twice. symbol disappears from display.On the day the Holiday Program is selected to begin, the 8th day program will be implemented. The display will show the Holiday symbol point, press once.s TROUBLESHOOTINGPROBLEM: Days are flashing, pressing any key does nothing except key turns output ON and OFF.SOLUTION: Time of Day and Day of Week have not been set. See “SETTING THE TIME”NOTE:This is the condition after a reset. If the timer is found in this condition after it has been installed, programmed and operating for a while, it may indicate that electrical noise or voltage transients have dis-rupted the microprocessor causing a loss of program information. Call 1-800-272-1115 and request that a no-charge “Snubber Filter” be sent to you to place across the input to the timer, which may solve the problem.A second, but very unlikely cause of loss of program is a power fail-ure with the backup battery low or dead. Check by disconnecting power and monitoring how long the battery keeps the time of day in the display.PROBLEM:Time of day was set while holding the key down,but days are still flashing.SOLUTION: Current day of week was not set while holding down the key. See “SETTING THE TIME”PROBLEM: It is 10AM and a ON program for 8AM was entered, but the output is not ON. Display shows the and symbols.SOLUTION: After programming, the timer does not “look back” to determine if it should be ON. Press the key (temporary override)to turn the output ON; appears in display. The timer will assume automatic operation at the next programmed event.PROBLEM: A program for 8AM Monday thru Friday was entered,but it will not accept it and CH1is flashing.SOLUTION: The ON or OFF was not entered as part of theprogram. ON or OFF must be selected.P r i n t e d i n U S A 082U S 010.97GRÄSSLIN GmbH & Co.

飞利浦66237电子钟说明书
以下是我找到的关于飞利浦66237电子钟说明书:
一、电池安装打开电池盒，按电池盒内极性标志，装入三节“AAA”7 号电池，如电池安装正确，产品将自动检测，显示屏自动全显示瞬间后，恢复到初试时间，20xx 年x 月x日 12 点整，初始温度25℃，同时发出“哔哔”的声。
否则重新安装电池。
二、查询、设置功能：
1、在正常时间显示状态下，且彩灯开关拨到“ON”或“OFF”时，连续按“M”键或轻触显示屏，显示屏按以下模式循环：TIME→TEMPERATURE→DATE→AL→TIMER，意思为时间→温度→日期→闹铃→定时器
2、在正常时间显示状态下，且彩灯开关拨到“TR”时，首次按“M”键或轻触显示屏，彩灯亮、显示保持时间显示界面，再连续按“M”键或轻触显示屏，显示屏按以下模式循环：TIME→TEMPERATURE→DATE→AL→TIMER，意思为时间→温度→日期→闹铃→定时器
秒信号产生器是整个系统的时基信号，它直接决定计时系统的精度，一般用石英晶体振荡器加分频器来实现。
将标准秒信号送入“秒计数器”，
“秒计数器”采用60进制计数器，每累计60秒发出一个“分脉冲”信号，该信号将作为“分计数器”的时钟脉冲。
“分计数器”也采用60进制计数器，每累计60分钟，发出一个“时脉冲”信号，该信号将被送到“时计数器”。
“时计数器”采用24进制计时器，可实现对一天24小时的累计。
译码显示电路将“时”、“分”、“秒”计数器的输出状态用七段显示译码器译码，通过七段显示器显示出来。
整点报时电路时根据计时系统的输出状态产生一脉冲信号，然后去触发一音频发生器实现报时。
