Language (Valid from next power on)
This item switches the display language for each of the screens. Each touch of the
language display area successively switches the display language in the following
order: English → Japanese → German → French→ Simplified Chinese*
→Traditional Chinese*. The language set here is only for the titles, etc. that are
displayed in each screen. To display text strings that are issued in the system history
or by the Print command correctly, an Operator Panel configured with the
appropriate code pages** must be used.
The settings become valid when the system is next started up.
The initial setting at shipment from the manufacturer is English.
* Simplified Chinese and Traditional Chinese are available with OP1 Ver.1.10 or
later.
** For details on code pages, refer to OP1 manual 5.3 About Display Language.
