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 an appropriate distance away from the screen. The distance
between the projector and the screen determines the actual size of the image.
3 Position the projector so that the lens is at a right angle to the screen. If the
projector is not at a right angle, the projected image will look distorted. To correct the
distortion, use the Keystone function. (see page 34)
4 Connect the power cord of the projector and the connected device to the wall outlet.
Ratio of upward projection: 100 %
