Making lens shift adjustments (Using the supplied lens shift gauge)
Use the supplied lens shift gauge to adjust vertical lens position.
* The illustrations in these operating instructions show the lens used with the PT-DZ770 projector.
1) As shown in the figure, fold the
lens shift gauge at right angles
along the dotted line.
z
Adjust so that the gauge plane of the lens shift
gauge and the front panel of the projector are
roughly in the same plane.
2) Move the lens to the home position.
z
For details on how to return the lens to the
home position, refer to the operating instructions
of the projector.
3) Adjust lens shift on the projector
so that the bottom edge of the
projected image aligns with the
line for the specific projector
model on the lens shift gauge.
z
Use the projector after making the adjustments
and lens position settings described here.

Focus Adjustment Function
Adjust focus after completing the lens shift adjustments.
The focal balance between the center and periphery of the projected image changes depending on the size of the
projected image. The lens is equipped with a focus balance adjustment function for the screen periphery.
Adjusting the Focus
Periphery focus adjustment ring
1) Focus the center of the screen by
operating the projector unit.
2) Turn the periphery focus ring by
hand as shown in the figure to
adjust the focus in the periphery
of the screen.
3) Again check focus at the center of
the screen and use the projector
controls to make fine adjustments.
Note
z
The projected image sizes and scale shown on the periphery focus adjustment ring are an approximate guide.
Note
z
After adjusting the lens position using the lens shift gauge, lens shift adjustments are possible within the range
where the projector will not interfere with the edges of the projected image.
