If you are experienced in setting up projection systems, use the Quick Setup card that was included. For complete details on connecting and operating the projector, refer to this User’s Guide.

The website also has technical specifications (an interactive image size cal- culator, laptop activation commands, connector pin outs, a glossary, the product data sheet), a web store to buy accessories, and a page for online registration.

Important Operating Considerations

Do not place the projector on a tablecloth or other soft coverings that may block the front or back vents. Do not use a non-approved ceiling mount. In the unlikely event of the bulb rupturing, thoroughly clean the area in front of the projector and discard any edible items that may have been placed in that area.
