In the interests of user-safety (Required by saf ety regulations in some countries) the set should be restored
to its original condition and only parts identical to those specified should be used.

Im lnteresse der Benutzersicherheit (erforderliche Sicherheitsregeln in einigen Ländern) muß das Gerät in seinen
Originalzustand gebracht werden. A ußerdem dürfen für die spezifizierten Bauteile nur identische Teile verwendet
werden.

OUTLINE

Based on the existing models XG-C40XU/XE, these models have their LCD panels redesigned.
This Service Manual covers only the modifications that are different from the base models. For the
unchanged service information, refer also to the Service Manual (S01B4XG-C40XU) for the base
models (XG-C40XU/XE).

BESCHREIBUNG

Die LCD-Bildschirme dieser Modelle wurden gemäß den vorhandenen Modellen XG-C40XU/XE
neu konstruiert. Diese Service-Anleitung beinhaltet die Veränderungen, welche sich von den
Grundmodellen unterscheiden.
Beziehen Sie sich für die unveränderten Service-Informationen der Grundmodelle (XG-C40XU/
XE) auf die Service-Anleitung (S01B4XG-C40XU).
