1) Install the projector in the installation location, and turn it on to project an image.
2) Move the lens to its home position.
3) Operate the projector to shift the focus of the entire projected image toward
the front of the screen.
4) Operate the projector to shift the focus toward the screen a little bit at a time until
one of the areas A to D in Fig. 1 just comes into focus on the screen, and then stop.
z
In this state, the “just focus points” of the unfocused areas are positioned just in front of
the screen. The distance between this position and the screen is the correction distance.
5) Insert the spacers between the body of the projector and the lens mounter, as
shown in Fig. 2.
z
Remove the lens mounter from the projector, and insert the spacers in the positions
that correspond to the unfocused areas.
z
The “just focus points” of the areas for which you inserted spacers will be corrected
toward the rear of the screen.
z
Make sure the adhesive surfaces of the spacers face the lens mounter when inserting them.
z
The correction distance is determined by the thickness and quantity of spacers
inserted. Insert spacers according to the correction distance.
(The unit for correction distances derived from the formulas in the following table is millimeters.)

Correction distance guide: When the projected image size is 1.52 m (60 in.), the cor-
rected distance when one 0.1 mm thick spacer is inserted is 120 mm.
Attention
z
Installing the lens mounter, be careful not to put wiring between the lens mounter and the
projector unit.
