15 PREPARATION
Projection Distance per Screen Size
1
Place the projector on a sturdy, level surface, together with the PC or audio/video
source.
2
Place the projector at an appropriate distance from the screen. The distance be-
tween the projector and the screen determines the actual size of the image.
3
Position the projector so that the lens is set at a right angle to the screen. If the
projector is not set at a right angle, the image on the screen will be tilted and the
image quality will be poor. If the screen image is crooked, use the Keystone function.
(see page 21)
4
Connect the power cords of the projector and the connected devices to the wall
outlet.
Ratio of upward projection: 100 %
