Installing the Projector (Cont.)
Relationship between Projection Distances and Projection Screen Sizes
CAUTIONS and NOTES
¥
When installing a screen, use a 4 : 3 aspect-ratio picture.
(A 16 : 9 aspect-ratio picture is projected based on the width of the range in which a 4 : 3 aspect-ratio picture is pro-
jected.)
¥The diagonal length of a 16 : 9 aspect-ratio screen is about 91.8% that of a 4 : 3 aspect-ratio screen. This value is only
a guide (reference).
¥If sunlight or lamp light strikes the projection screen directly, the picture tends to become whitish and dim. Be sure to use
a curtain, etc. to shield the light.
¥Trapezoidal distortion may not be corrected. Set the projector horizontally on a surface that is within the range of adjust-
able angles (up/down adjustment angle: +7¡ ; horizontal adjustment angle: ±1.5¡).
¥The values listed in table ÒRelationship between Projection Distances and Screen SizesÓ are provided only as a guide
(reference). The projected screen size may vary depending on the manufacturing tolerance of the projection lens.
¥When hanging the from the ceiling, use a dedicated hanging fixture.
Setting the Amount of Lens Shifting
This projector features a lens shifting function which allows you to shift the projection screen up and down in position. Depending
on installation conditions (such as dual stacking), you may need to use this function to make adjustments.
NOTES
¥
The amount of shifting is within the range of approx. 30% to 55%. The factory setting is 50%.¥After finishing the lens shift setting (adjustment), tighten the SHIFT LOCK fixing bolt firmly so the lens will not move.
1Loosen the SHIFT LOCK fixing
bolt.
Use the hex wrench supplied.
2Rotate the LENS SHIFT knob to
adjust the position (shift amount)
of the projection screen.
Rotate it to the right: The lens shifts upward.
Rotate it to the left: The lens shifts downward.
3Tighten the SHIFT LOCK fixing
bolt firmly.
Use the hex wrench supplied.
