This document is the User's Guide for EPSON® PowerLite® 50c/70c Multimedia Projector, providing important safety information and usage precautions. It mentions not to look into the projector lens when the lamp is turned on to avoid eye damage; not to let children look into the lens when it is on; not to open any cover on the projector except the lamp and filter covers due to dangerous electrical voltages; not to attempt self-service and refer all servicing to qualified personnel; keeping plastic bags away from children to prevent suffocation; and not to touch the new lamp with bare hands when replacing it to avoid shortening the lamp life.
