A - 2 TECRA A3/S2 Series Maintenance Manual 3. If the panel’s surface gets dirty, wipe it with cotton or a soft cloth. If it is still dirty, try breathing on the surface to create a light condensate and wipe it again. If the surface is very dirty, we recommend a CRT cleaning agent.
TECRA A3/S2 Series Maintenance Manual A - 3 5. Glass is used in the panel, so be careful not to drop it or let it strike a hard object, which could cause breakage or cracks. 6. CMOS - LSI circuits are used in the module, so guard against damage from electrostatic discharge.
A - 4 TECRA A3/S2 Series Maintenance Manual 7. Do not expose the mod ule to direct sunlight or strong ultraviolet rays for long periods. 8. Do not store the module at temperatures below specifications. Cold can cause the liquid crystals to freeze, lose their elasticity or otherw ise suffer damage.
TECRA A3/S2 Series Maintenance Manual A - 5 10. If you transport the module, do not use packing material that contai ns epoxy resin (amine) or silicon glue (alcohol or oxime). These materials can release gas that can damage the panel’s polarization.

Ein wichtiger Punkt beim Kauf des Geräts Toshiba S2 (oder sogar vor seinem Kauf) ist das durchlesen seiner Bedienungsanleitung. Dies sollten wir wegen ein paar einfacher Gründe machen:
Wenn Sie Toshiba S2 noch nicht gekauft haben, ist jetzt ein guter Moment, um sich mit den grundliegenden Daten des Produkts bekannt zu machen. Schauen Sie zuerst die ersten Seiten der Anleitung durch, die Sie oben finden. Dort finden Sie die wichtigsten technischen Daten für Toshiba S2 - auf diese Weise prüfen Sie, ob das Gerät Ihren Wünschen entspricht. Wenn Sie tiefer in die Benutzeranleitung von Toshiba S2 reinschauen, lernen Sie alle zugänglichen Produktfunktionen kennen, sowie erhalten Informationen über die Nutzung. Die Informationen, die Sie über Toshiba S2 erhalten, werden Ihnen bestimmt bei der Kaufentscheidung helfen.
Wenn Sie aber schon Toshiba S2 besitzen, und noch keine Gelegenheit dazu hatten, die Bedienungsanleitung zu lesen, sollten Sie es aufgrund der oben beschriebenen Gründe machen. Sie erfahren dann, ob Sie die zugänglichen Funktionen richtig genutzt haben, aber auch, ob Sie keine Fehler begangen haben, die den Nutzungszeitraum von Toshiba S2 verkürzen könnten.
