FOCUS ADJUSTMENT (For Model 38-809043-02)
Set up the projector and project image on the screen.
1. Loosen the Focus Lock Screw on the projection
lens.
2. Rotate the projection lens to obtain proper focus
on center area of the screen.
When the distance of the screen and lens is 1 meter,
set
mark (yellow) of the lens on Focus Lock Screw
position.
3. Lock the Focus Lock Screw securely.
When proper focus is not observed at outer area of
the screen, proceed following adjustments.
4. Loosen the Focus Lock Ring on the projection
lens. (Turn the Lock Ring counter-clockwise.)
5. Rotate the lens to obtain proper focus on outer
area of the screen.
6. Lock the Focus Lock Ring securely. (Turn the Lock
Ring to clockwise.)
If proper focus is not observed over the entire screen,
repeat above adjustments 1~ 6.
When the lens is attached to the projector and images are being projected onto the screen, the
peripheral focus may be out of focus in some localized areas. If this happens, insert the accessory in
between the lens attachment and the lens to correct the focus.
Inserting the spacers corrects the distance for best
diagonal focus at the screen.
The corrected distance is determined by the thickness
of the spacers that are used. As a guide, the distance is
adjusted by approximately 30 mm for each 0.1-mm
thickness of the spacers.
There are three types of spacers provided, and there
are four of each spacer type. Use these spacers to
correct the distance as required.
Spacer "1"
Color; Clear
Thickness; 0.1 mm
Spacer "2"
Color; Black
Thickness; 0.2 mm
Spacer "1"
Color; Cream
Thickness; 0.3 mm
