key.
- The [SELF DIAGNOSITICS] menu will be displayed, and each item will be checked. If the
result of each diagnosis is normal, "OK" will be displayed. If the result is abnormal, "NG" will
be displayed. If any abnormality occurs, consult our service center.
* In the FROM(TYPE)CHECK (object type check), the conditions are
checked in the order of the object type numbers (00 _ 01_ ... _15). If
an abnormality is found, the corresponding object type number will be
displayed, and the next FROM(PROG.)CHECK (program check) will
be started without checking the conditions of the remaining object
types.
