This section describes how to set up your projector and how to connect video and audio sources.
Your projector is simple to set up and use. But before you get started, you must first:
1 Set up a screen and the projector.
2 Connect your computer or video equipment
to the projector.
(→ page 13,14,15,16,17,18)
3 Connect the supplied power cable.
(→ page 19)
NOTE: Ensure that the power cable and any
other cables are disconnected before moving
the projector. When moving the projector or
when it is not in use, cover the lens with the
lens cap.
