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 relevant web
addresses.
