Changing the Lens

Info

• Before changing the lens, turn off the power of the projector and remove the power cord from the wall outlet.

• Do not attempt to change the lens while the projector is mounted on the ceiling.

1 Remove the lens housing cover by us-

ing the supplied lens housing cover removal tool to push down on the groove on the lens housing cover.

• Hold down the lens housing cover with your hand to prevent it from flying out.

2 Slide the lens fastener catch tab in the

direction of “UNLOCK” while holding the lens to prevent it from falling out.

• Slide the lens fastener catch tab until the window located beside “LOCK” comes to the top. Look inside the window to make sure that the two grooves on the lens fastener ring are facing up.

3 Remove the lens by pulling it straight out. 4 Remove the protection cap from the back

of the new lens.

6 Slide the lens fastener catch tab in the

direction of “LOCK” until it stops.

• Be careful not to rotate the lens fastener ring too tight, as the lens fastener ring will be difficult to loosen the next time the lens is changed.

7 Replace the lens housing cover.

• If the lens housing cover is not secured to the projector, you will not be able to turn the power on.

• When the distance from the lens center to the bottom of the image [H] is a negative number,

this indicates that the bottom of the image is below the lens center.

Handling Precautions

● Do not disassemble this lens.

Please refer to your authorized dealer for any maintenance and inspections requiring an open cabinet.

● Touching any internal parts other than the lens fastener catch tab can cause personal injury or machine malfunction.

Öffnen Sie die Objektivabdeckung mit dem beiliegenden Objektivabdeckungsstab, indem Sie diesen in die Nut an der Objektivabdeckung drücken.

• Halten Sie die Objektivabdeckung dabei mit der Hand zurück, damit sie nicht herausspringt.

Halten Sie das Objektiv zum Abnehmen mit einer Hand fest, damit es nicht herunterfällt, und schieben Sie die Objektivbefestigungsnase in Richtung „UNLOCK“.

• Drehen Sie die Objektivbefestigungsnase so weit, dass das neben „LOCK“ befindliche Fenster nach oben gewendet ist. Vergewissern Sie sich durch das Fenster, dass die beiden Nuten am Objektivbefestigungsring oben liegen.
