Read this rst! Always follow these precautions
WARNING:
Before replacing the projection lens, be sure to turn off the power 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:
Do not use the lens with the protective lm and lens cover 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.
Note
zThis product cannot be used if an optional frame (ET-PFD510C / ET-PFD310C) is attached
and used with the projector.

4-ENGLISH
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

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, the lens position can be
adjusted within the adjustment range described in "Adjustment range by the lens position
shift (optical shift)" (Page 12).
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

8-ENGLISH
 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-SRZ31KC / PT-SRS30KC / PT-SRQ13KC / PT-SRZ12KC /
PT-SRS11KC / PT-SDZ21K2C / PT-SDS20K2C / PT-SDW17K2C / PT-SDZ18K2C /
PT-SDZ985C / PT-SDS955C / PT-SDZ981C
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-SDW935C
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.
