Installing
Projected Image and Position of Projector
Install the projector as follows.
Installing in parallel with the screen
If the projector is installed at an angle to the screen, keystone distortion occurs in the projected image.
Adjust the projector's position so that it is installed in parallel with the screen.
c
If the projector cannot be installed in front of the screen, you can adjust the position of the image
by using lens shift.
s p.29
Installing the projector horizontally by adjusting the height of either side
If the projector is tilted, the projected image is also tilted.
Install the projector horizontally so that both sides are at the same height.
If the projector cannot be installed horizontally, you can adjust the projector's tilt with the front foot.

Various Setting Methods
Warning
•A special method of installation is required when suspending the projector from a ceiling (ceiling mount). If
it is not installed correctly, it could fall causing an accident and injury.
•If you use adhesives, lubricants, or oil on the ceiling mount fixing points to prevent screws from loosening,
or if you use things such as lubricants or oils on the projector, the projector case may crack causing it to fall
from its ceiling mount. This could cause serious injury to anyone under the projector and also damage the
projector.
•Do not install it on an unstable shelf or in a place out of load range. Otherwise, it could fall or topple causing
an accident and injury.
•When installing it in a high position such as on a shelf, take measures against falling by using wires to ensure
the safety in an emergency, such as an earthquake, and prevent accidents. If it is not installed correctly, it
could fall causing an accident and injury.
•Do not block the air intake vent and air exhaust vent of the projector. Blocking its air intake vent and air
exhaust vent may trap heat inside causing fire.
Attention
•Do not setup the projector in locations subject to high humidity and dust, or in locations subject to smoke
from fires or tobacco smoke.
•Do not use the projector installed vertically. Doing so could cause a malfunction.
•Clean the air filter once every three months. Clean it more often if the environment is particularly dusty.
sp.84
Placing on a table and projecting
You can install the projector on a table in your living room or on a low shelf to project images.
Suspending from the ceiling and projecting
You can suspend the projector from the ceiling with the optional ceiling mount to project images.

Preparing

c
When suspending from the ceiling and projecting, set Projection to Front/Ceiling or Rear/
Ceiling.
s Extended - Projection p.65
Projection Distance and Lens Shift Maximum Values
The size of the projection increases as the projector is moved away from the screen.
Use the table below to setup the projector at the optimum position from the screen. The values given here
are for your reference only.
The maximum lens shift adjustment values are shown in the following table.
c
The projected image becomes smaller after correcting distortion. Increase the projection distance
to fit the projected image to the screen size.
When adjusting the projection position vertically in lens shift
A : Distance from the center of the lens to the bottom edge of the projected image (when lens shift is raised
to its highest level)
B : Distance from the center of the lens to the bottom edge of the projected image (when lens shift is lowered
to its lowest level)
E : Projection distance from the projector to the screen
F : Size of the projected image

Preparing

When adjusting the projection position horizontally in lens shift
C : Lens center movement distance when the projector is moved (when lens shift is set to maximum left)
D : Lens center movement distance when the projector is moved (when lens shift is set to maximum right)

Connecting a Device
Attention
•Make cable connections before connecting to a power outlet.
•Check the shape of the cable's connector and the shape of the port, and then connect. If you force a connector
of a different shape into the port, it could cause damage and a malfunction to occur.
Removing the Terminal Cover
Depending on the model you are using, the projector may have a terminal cover for the connector section
on the rear to improve the overall appearance of the projector. Remove the terminal cover before connecting
any cables.
There are gaps at the bottom of the terminal cover that allow you to pull the cover forward and lift it from
the grooves at the top.
When reattaching, first insert the protruding sections into the grooves at the top.
Connecting Video Equipment
To project images from DVD/Blu-ray players, connect to the projector using one of the following methods.
When using a commercially available HDMI cable
c
•When using the power supply port for an optical HDMI cable, connect it to the Opt.HDMI port.
•When projecting images in HDCP 2.2, connect to the HDMI1 port.
•This projector does not have a built-in speaker. Connect the projector to your AV system to listen to
audio from connected equipment.
Connecting a Computer
To project images from a computer, connect the computer using one of the following methods.
