If you are experienced in setting up presentation systems, use the included Quick Set Up card. For complete details on connecting and operating the projector, refer to this User’s Guide. Electronic versions of this User’s Guide in multiple languages are available on the included CD and on our website.

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. See the inside of the back cover for a list of all contact numbers and relevant web addresses.

Important Operating Considerations

Do not place the projector on a tablecloth or other soft covering that may block the vents. Vents are placed along the back, left and front sides of the projector. Do not use a non-approved ceiling mount. In the unlikely event of the lamp rupturing, discard any edible items placed in the surrounding area and thoroughly clean the area along the sides and in the front of the projec- tor.

Do not place objects in the areas along the left, back and front sides of the projector
