REMEDY FOR NO. 0010/4000/8000
If the Maintenance Request No. 0010/4000/8000 occurs, take the following measure according to the procedure below.
NOTE : There is a priority for occurrence of No. 0010/4000/8000. Because No. 0010 has the priority, when both No. 0010 and No. 4000 (or No. 8000) occur at the same time, No. 4000 (or
No. 8000) is not displayed, but No. 0010 is displayed only. When the cause of No. 0010 is removed, No. 4000 (No. 8000) is displayed then.
