(VT580/VT480/VT58/VT57/VT595/VT590/VT491/VT490/VT59)
Use this guide when considering the distance to the screen and the screen size.
• The ceiling mount unit can be adjusted up and down a maximum of +/-10˚, but if too much
of an angle is taken the image will show some distortion. Therefore, it is recommended that
an adjustment is made in conjunction with the screen projection angle.
• Recommended screen sizes for projectors are from 21 inches to 300 inches. (Screen sizes
represent the diagonal dimension.)
(*1) Distance from center of fixed ceiling part to end of main unit lens.
(*2) Distance of lens center from ceiling mount surface of fixed ceiling part.
(*3) The angle is 8.3 to 8.6˚ using a telephoto setting for distances from lens center (horizontal) to screen center.
(*4) The angle is 9.9 to 10.3˚ using a wide angle setting for distances from lens center (horizontal) to screen center.
Using the Diagrams
Referring to the diagram, screen sizes that can be used at a projection distance of 3 m will range from 82
inches to 97 inches.
To project to a screen size of 200 inches, the projection distance will range from 6.2 m to 7.4 according
to the diagram.
See Page 8 for the vertical and horizontal dimensions of the screen size.
The projection distance is a calculated value and as such,
there is a tolerance of +/- 5%.
