Projection Distance Table
Figures of Installation Dimensions
To find the appropriate screen size, see the following figures when installing. The values are only rough
estimates.
The recommended range for the projection distance (a) is 62 to 311 mm.
The offset value for the position of the center of the projected image and the center of the wall plate is 70.5
mm.
When the projected image size (S) is 75 inches or more, the scale on the arm slide (b) is equal to the projection
distance (a).
The numbers for (a) and (b) differ if the projected image size (S) is less than 75 inches.
When installing the Touch Unit, install it on the screen that is being used for projection.
You need at least 120 mm distance between the top edge of the projected image and the top edge of the
the actual screen to install the Touch Unit.
Caution
Leave the following gaps around the edge of the screen.
•
From the top of the projected image to the bottom of the Touch Unit: 25 mm
•
From the edges of the projected image to the edges of the screen: At least 100 mm left and right
•
From the bottom of the projected image to the bottom of the screen: At least 20 mm
If there are obstacles such as cables, whiteboard trays, holders, or frames within the areas noted above,
the Touch Unit will not operate correctly.
