Next, the operation will be explained.

The current time can be adjusted by pressing the display changeover switch 8. To adjust the current time, use the hour changeover switch 5.
The hour unit is adjusted using the button 6, and the minute unit is adjusted using the minute changeover switch 6. Next, by pressing the display changeover switch 8 again, the first stage time can be set. Then, the set time is stored in the register 1-1 in step STI.

Next, in step ST2, 0:00 minutes are set in the register 1-2. Then, the display changeover switch 8 is pressed again to set the second stage time, and in step ST3, the current time is entered into the register 2-1. Next, in step ST4, it is determined whether the second stage time is greater than the first stage time, and if it is, the process proceeds to step ST5, where the time obtained by subtracting the first stage time from the second stage time is stored in the register 2. -2. If it is smaller, the process proceeds to step ST6, and the time obtained by adding 24 to the second stage time and subtracting the first stage time from that value is stored in the register 2-2.

By pressing the display changeover switch 8 again, the third stage time can be set. In step ST7, the third stage time is set, and this time is stored in the register 3-]. In step ST8, it is determined whether the time in the third stage is greater than the time in the first stage, and if it is, the process proceeds to step ST9.
The time obtained by subtracting the time of the first stage from the time of the first stage is stored in register 3.
