Setting up
Installation mode
There are four ways to set up the projector. Set the [PROJECTOR SETUP] menu → [PROJECTION METHOD] 
(x  page   111) depending on the installation mode. Set [COOLING CONDITION] to [AUTO]. Using the projector 
with [COOLING CONDITION] set incorrectly may shorten the life of the lamp.

Parts for ceiling mount (optional)
The projector can be installed on the ceiling by combining the optional Ceiling Mount Bracket (Model No.: 
ET
-
PKD120H (for high ceilings), ET
-
 PKD120S (for low ceilings), ET
-
 PKD130H (for High Ceilings, 6-axis 
Adjustment)) and the Ceiling Mount Bracket (Model No.: ET
-

PKD130B (Projector Mount Bracket)).
 fBe sure to use the ceiling mount bracket specified for this projector .
 fRefer to the Installation Instructions of the ceiling mount bracket when\
 installing and setting up the projector

.
Attention
 f To ensure projector performance and security, installation of the Ceiling Mount Bracket must be carried out by your dealer or a qualified 
technician.
Projected image and throw distance
Refer to the projected image size and projection distance to install the\
 projector. Image size and image position 
can be adjusted in accordance with the screen size and screen position. When the fixed-focus lens (Model No.: 
ET
-

DLE030) is attached, the projection relation between the screen and the\
 projector differs from that of other 
lenses. Refer to “For fixed-focus lens (Model No.: ET
-

DLE030)” (x
  page   33) for details.

Attention
 fBefore setting up, read “Precautions for use” ( x   page   18).
Especially when the fixed-focus lens (Model No.: ET- DLE030) is used, install the projector so its back plane is parallel to the screen so the 
projected image is rectangular.
The vertical keystone distortion in moderate range can be corrected by the [POSITION] menu  → [GEOMETRY] → [KEYSTONE] → 
[VERTICAL KEYSTONE] (x
  page   86) even after it is installed. For the range that can be corrected, refer to “[GEOMETR Y] projection 
range” (x
  page   34).
 fDo not use the projector and the high-powered laser equipment in the same room.  The DLP

 chips can be damaged if a laser beam hits the 
projection lens surface.

Note
 f When [GEOMETR Y] is used, the focus of the entire screen may be lost as correction increases. fMake the curved screen a circular arc shape with one part of a perfect circle removed. fAdjustment range of the [GEOMETR

Y] items may not match the listed projection range depending on the projection lens. Use this projector 
within the projection range, otherwise the correction may not work.

*1 The throw ratio is based on the value during projection of 2.03  m (80") projected image size. When the fixed-focus lens (Model No.: ET- DLE030) is 
attached, it is based on the value during projection of 2.54   m (100") projected image size.
*2
 
When the fixed-focus lens (Model No.: ET-
 DLE030) is attached, the projection relation between the screen and the projector dif fers from that of 
other lenses. Refer to “For fixed-focus lens (Model No.: ET
-

DLE030)” (x
  page   33) for details.
*3
 
When the fixed-focus lens (Model No.: ET-
 DLE055) is attached, the lens shift is not possible, therefore the height position (H) becomes SH/2.

*1 The throw ratio is based on the value during projection of 2.03   m (80") projected image size. When the fixed-focus lens (Model No.: ET- DLE030) is 
attached, it is based on the value during projection of 2.54   m (100") projected image size.
*2
 
When the fixed-focus lens (Model No.: ET-
 DLE030) is attached, the projection relation between the screen and the projector dif fers from that of 
other lenses. Refer to “For fixed-focus lens (Model No.: ET
-

DLE030)” (x
  page   33) for details.
*3
 
When the fixed-focus lens (Model No.: ET-
 DLE055) is attached, the lens shift is not possible, therefore the height position (H) becomes SH/2.
