3-2. Projector Set Up

Ambient Light

Whenever you have a choice, light the room from the rear, away from the projection screen. The MP8660 has a brightness adjustment to achieve the best image possible.

Distance to Viewing Screen

The MP8660 can be used in a small or large meeting room to project a quality image from 51 cm (20 inches) to 762 cm (300 inches) in size. The distance between the projector and the viewing screen and the zoom lens setting (minimum to maximum) will determine the size of the projected image. Refer to the Technical Appendix 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.

Carrying Handle

The MP8660 has a carrying handle that folds into the top of the projector housing. To raise the handle, push up on the back end of the handle (Figure 3-14) and then lift upward.

Technical line drawings of mechanical components with directional arrows indicating movement (no text or symbols)

Figure 3-14. Unfolding Handle

Ceiling Mount Considerations

An optional ceiling mount bracket (Figure 3-15) is required to install the MP8660 from the ceiling. For this type of installation, the image must be vertically and horizontally inverted.

See section 9-1 to order the ceiling mount kit.

Figure 3-15. Optional Ceiling Bracket

Adjusting the Projector Elevation

The elevation can be adjusted by turning the foot adjuster (Figure 3-16) to raise or lower the angle of the projector.

Technical line drawing of a mechanical component with internal grid structure and directional arrows (no text or symbols)

Figure 3-16. Foot Adjusters

Note

Both adjusting feet must be raised or lowered the same amount to project a level image on the viewing screen. The elevation can be adjusted from approximately 0.4 to 7.2 degrees.

Rear Projection

A semi-transparent screen (Figure 3-17) 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 horizontally inverted.

Notes:

1. “Mode” denotes the computer mode determined by the projector. The number can be read by the read command through RS-232 interface.
2. Advanced scaling is used for all inputs that are not 800 x 600.
3. Mode 10 and 140: For XGA, full advanced scaling (vertical and horizontal) is used. Modes 11–13 and 14: Only vertical advanced scaling is used.
4. The synchronization signal widths represent the number of dots (horizontal) and the number of lines (vertical).

5. H-size denotes the standard number of dots in the horizontal period.

6. For the MAC16 and MAC19A/B computers, you must manually set the MAC MODE to "ON" to determine the correct modes.

Set the MAC MODE to "OFF" for the following computer modes:

D MAC16 as SVGA75
D MAC19A as XGA60
D MAC19B as XGA75

See Setup Sub-Menu to set MAC MODE.

1. Computer name (in right column) appears when you display the TEST SCREEN on the projector.
