Network setup
When connected to a local area network (LAN) through the RJ-45 connector, the projector can be controlled remotely through a Web browser by any of the clients (PCs connected to the LAN) on the LAN. The projector can also be accessed outside the LAN, with a correctly configured firewall.
Cleaning the lens
To clean the lens, complete the following procedure:
1. Apply a non-abrasive camera lens cleaner to a soft, dry cloth. Note: Avoid using an excessive amount of cleaner, and do not apply the cleaner directly to the lens. Abrasive cleaners, solvents or other harsh chemicals might scratch the lens.
2. Lightly wipe the cleaning cloth over the lens in a circular motion. If you do not intend to use the projector immediately, replace the lens cap.

CASIO Ultra Portable Projectors PDF Installation Instructions Manual
With an exclusive zoom lens, our new portable projector can fit an image on any screen, from virtually any position in the room. That’s because the Casio XJ-450’s and XJ-350’s 2x optical zoom lens features the highest magnification of any portable on the market. The auto- matic exclusive H & V keystone correction feature of the XJ-450 quickly “squares up” your image, even from extreme angles. Along with a com- pact, lightweight design and the ability to project in daylight, it’s easy to see how the XJ-450 and XJ-350 outshine the competition. A complete innovation – in fact, nothing short of a revolution.
