Error List

When a display has a technical fault, a numeric error code ap-
pears that will enable the maintenance operator to identify the
possible cause.
There are 3 categories of errors:
1 Permanent: errors that require a manual reset
2 Temporary: errors that are automatically reset once the
cause that generated them is removed or stopped
3 Notices: simple warnings that do not block the appliance's
operation
