SELF-DIAGNOSIS DISPLAY
This unit displays the results of the self-diagnosis it carries out in two digits on the front panel indicator when problems occur.
Although these digits will only roughly tell you what kind of problems have occurred, use them when servicing the unit.
1, Displaying the Self-Diagnosis Results
●Press the STOP button for about 10 seconds continuously. Two digits (see below) showing the results of the self-diagnosis
will be displayed for three seconds at the hours part of the timer. All other parts of the timer will go off. The time will
automatically return after the three seconds.
●If no mechanism unit problems have occurred up to now, “00” will be displayed.
