4. Projection Distance Table

Refer to the table below and install the setting plate and projector to project images at an appropriate size on
the projection surface. The values are only rough estimates.
The recommended range for the projection distance (a) is 62 to 311 mm.
The numbers on the slider measure (b) are the same as the projection distance (a) when the screen size (S) is
70 inches or more. Because the installation position of the projector changes when S is less than 70 inches, the
numbers for a and b differ.
