3-2. Projector Set Up
The meeting room is your operating environment and any stray light hitting the projection screen will become
glare. It is best to use a meeting room without wide-open windows. If there are “light stripes” from venetian
blinds, try to find a viewing area that’s away from them – and remember, the light stripes will move as the
hour changes.
Ambient Light
Whenever you have a choice, light the room from the rear, away from the projection screen. The MP8020 has
a brightness adjustment to achieve the best image possible.
Distance to Viewing Screen
The MP8020 can be used in a small or large meeting room to project a quality image from 46 cm (18 inches)
to 762 cm (300 inches) in size. The distance between the projector and the viewing screen (see “a” in
Figure 3-15) and the zoom lense setting (minimum to maxium) will determine the size of the projected image.
Refer to the table in Section 9-2 to determine how far away from the viewing screen you need to place the
projector to fill the screen with the projected image.
Remember that increasing the projector-to-screen distance also decreases the image’s brightness dramatically.
In other words, as the image grows larger, it also grows dimmer.
For best results, experiment to find the right combination of projector-to-screen distance and room lighting.
Ceiling Mount Considerations
An optional ceiling mount bracket (Figure 3-12) is required to install the MP8020 from the ceiling. For this
type of installation, the image must be inverted. Refer to section 4-4 Inverting the Image for more details.

Rear Projection
A semi-transparent screen (Figure 3-13) can be used to project an image and view it from the backside of the
viewing screen. For this type of installation, the image must be inverted. Refer to section 4-4 Inverting the
Image for more details.
