Read this rst! Always follow these precautions
WARNING:
Before replacing the projection lens, be sure to turn the power off and
disconnect the power plug from the wall outlet.
zUnexpected projection of light may cause injury to eyes.
zReplacing without removing the power plug may result in electrical shock.
Do not place objects near the light projecting surface.
zThis surface produces intense light. Failure to heed this warning could result in re
or burn injuries.
CAUTION:

Supplied accessories and consumables:
Do not use the lens with the protective lm and lens cap left on.
zIf left on, the heat generated during projection could melt them resulting in projector
deformation and damage, and personnel attempting to remove them could suffer
burn injuries.
Do not open the desiccant bag. Do not eat the contents.
(Inadvertently ingesting desiccant could be harmful.)
zIf the desiccant gets into your eyes or mouth, immediately rinse with plenty of water
and seek medical attention.
zKeep desiccant out of the reach of children.

Before replacing the projection lens
Return the projection lens to the home position before replacing or removing it.
For details on how to return the lens to the home position, refer to the operating instructions of the projector.
Attention
zMake sure that the projector power supply is switched off before attaching or detaching the projection lens.
zAfter removing the projection lens, store it safely away from vibration or impacts.
zBefore attaching the xed-focus lens, remove the protective lm from the light projecting surface and the lens
cap from the lens.
zBe sure not to touch the light projecting surface or the surface of the lens. Any ngerprints or smudges on
these surfaces will be magnied and lower the quality of the image displayed on the screen.
zThe light projecting surface and lens are made of glass. The lens could be damaged if brought into contact
with or rubbed against hard objects. Handle the lens carefully.
zUse a clean, soft and dry cloth to wipe away any dirt or dust that has adhered to the light projecting surface or lens.
Do not use uffy cloths containing oil, water or dust for cleaning.
zWhen the xed-focus lens is removed from the projector, place it with the light projecting surface facing
upwards.

Note
zThe illustrations of projectors in this manual are for informational purposes only and do not represent a specic
projector model. Congurations may vary with the model.
zAfter setting the lens position using the function on the projector or using the lens shift gauge, the lens position
can be adjusted within the adjustment range noted in "Adjustment range by the lens position shift (optical
shift)" (Page 11).
Then dimensions A1 and A2 will change according to lens shift amount.
zDimension L4 is the distance from the projector rear panel to the screen.
zDimension A2 is the distance from the bottom edge of the screen to the bottom of the adjustable projector legs
(with the legs fully screwed in).
Attention
zDimension L4 is not the distance from the projector rear panel to a wall, but the distance from the projector
rear panel to the screen. Provide at least 500 mm (19-11/16") of ventilation space between the projector rear
panel and a wall or other object.
When placing the projector in a conned space, a ventilation and/or air conditioning system is required.
Exhaust heat may accumulate when the ventilation is not sufcient triggering the protection circuit of the projector.
Projection relationships

ENGLISH-7
 Keystone distortion correction
When attaching this lens for use, regardless of the projector model, set up the projector so that the projected
image is rectangular and the back of the projector and the screen are parallel.
In addition, depending on the projector used, keystone distortion correction may be feasible after setup.
zWhen using one of PT-DZ21K / PT-DS20K / PT-DZ16K / PT-DZ13K / PT-DS12K / PT-DZ10K
For keystone distortion in the vertical direction generated within the angle range below, select [MAIN MENU] →
[POSITION] →[GEOMETRY] →[KEYSTONE] →[VERTICAL KEYSTONE] to perform correction.
Keystone distortion in the vertical direction greater than this angle and keystone distortion in the horizontal
direction can be corrected but the projected image overall will no longer be in focus.
Correction feasible angle (α): 0 - 5°
zWhen using PT-DW17K / PT-DW11K
If keystone distortion in vertical direction or horizontal direction is corrected, the projected image overall will no
longer be in focus. Set up the projector so that the projected image is rectangular and the back of the projector
and the screen are parallel.
zWhen using a projector other than one listed above
Please see "Setting up" in the operating instructions for the projector you are using.

Lens position setup (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-DZ21K projector.
1) As shown in the gure, fold the
lens shift gauge at right angles
along the dotted line.
zAdjust 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.
zFor 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 specic projector
model on the lens shift gauge.
zUse the projector after making the adjustments
and lens position settings described here.
Note
zThe lens position set using this procedure is the minimum value of A1 of "Projected image size and Projection
distance" in the Appendix. Perform adjustment manually to move to the maximum value.
zAfter setting the lens position using the lens shift gauge, the lens position can be adjusted within the
adjustment range noted in "Adjustment range by the lens position shift (optical shift)" (Page 11).
Lens position setup and focus adjustment (continued)
Note
zThe lens position set using this procedure is the minimum value of A1 of "Projected image size and Projection
distance" in the Appendix. Perform adjustment manually to move to the maximum value.
zThe lens position set using this procedure may deviate slightly from the adjustment made using the lens shift
gauge.
zAfter moving to the base position, the lens position can be adjusted within the adjustment range noted in
"Adjustment range by the lens position shift (optical shift)" (

Page 11).
zDepending on the (OSD) display position on the menu screen, there are cases where the projected light is
obstructed and a part of the menu is not displayed on the screen. In this case, open [MAIN MENU] →[DISPLAY
OPTIONS] →[ON-SCREEN DISPLAY] →[OSD POSITION] and change settings so that the whole OSD menu
can be seen.

Focus Adjustment Function
After setting the lens position, adjust the focus.
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
1) Focus the center of the screen by
operating the projector unit.
2) Loosen the lock screw and turn
the periphery focus adjustment
ring by hand as shown in the
gure to the left to adjust the
peripheral focus on the screen.
3) Again check focus at the center of
the screen and use the projector
controls to make ne adjustments.
4) Tighten the lock screw.
zThe periphery focus adjustment ring is locked.
Note
zThe projected image sizes and scale shown on the periphery focus adjustment ring are an approximate guide.
