Maintenance

The projector needs proper maintenance. Keep the lens clean because dust, dirt, or spots will project on the screen and diminish image quality.

Keep the projector housing clean to maintain its appearance.

Before cleaning the lens or housing, always turn off the power first and unplug the power cord.

Note that only the lamp is replaceable. If any other parts need replacing, contact your dealer or qualified service personnel.

Warning—Never open any of the covers on the projector except the lamp cover. Dangerous electrical voltages inside the projector can cause serious injury. Do not attempt to service the projector yourself. Refer all servicing to qualified service personnel.

Cleaning the Lens

1.Turn off the projector and let it cool down. Make sure the lens is also cool.

2.Wipe the lens in a circular motion with lens cleaning paper. Do not touch the lens with your hands.

Always keep the lens cap on the lens when the projector is not in use.
