Replacing the remote control batteries
If delays in the responsiveness of the remote control occur or if it does not
operate after it has been used for some time, it probably means that the
batteries are becoming flat. When this happens, replace them with new
batteries. Have two AA size manganese or alkaline batteries ready. You
cannot use other batteries except for the AA size manganese or alkaline.
Attention
Make sure you read the following manual before handling the batteries.
sSafety Instructions
a
Remove the battery cover.
While pushing the battery compartment cover catch, lift the cover
up.
b
Replace the old batteries with new batteries.

Preparing the Projector
This chapter explains how to install the projector and connect projection sources.

Installation Methods
The projector supports the following four different projection methods.
Install the projector according to the conditions of the installation location.
•Project images from in front of
the screen. (Front projection)
•Project images from behind a
translucent screen. (Rear projec‐
tion)
•Suspend the projector from the
ceiling and project images from
in front of a screen. (Front/Ceil‐
ing projection)
•Suspend the projector from the
ceiling and project images from
behind a translucent screen.
(Rear/Ceiling projection)
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 on the Ceiling mount fixing points to prevent the 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 ceiling mount
and could damage the projector.
When installing or adjusting the ceiling mount, do not use adhesives to
prevent the screws from loosening and do not use oils or lubricants and so
on.
Attention
•Do not use the projector on its side. This may cause malfunctions to occur.
•Do not cover the projector's air intake vent or air exhaust vent. If either of
the vents are covered, the internal temperature could rise and cause a fire.
a
•An optional Ceiling mount is required when suspending the
projector from a ceiling.
s"Optional Accessories" p.118
•You can change the setting as follows by pressing down the [A/V
Mute] button on the remote control for about five seconds.
FrontWFront/Ceiling
Set Rear or Rear/Ceiling from the Configuration menu.
sExtended - Projection p.81
Installation methods
Install the projector as follows.
Installing the Projector
19

•Install the projector so that it is parallel to the screen.
If the projector is installed at an angle to the screen, keystone distortion
occurs in the projected image.
•Place the projector on a level surface.
If the projector is tilted the projected image is also tilted.
a
•See the following if you cannot install the projector parallel to the
screen.
s"Correcting Keystone Distortion" p.36
•See the following if you cannot install the projector on a level
surface.
s"Adjusting the Horizontal Tilt" p.39
Screen Size and Approximate Projection Distance
Projection size is determined by the distance from the projector to the
screen. See the illustrations on the right to select the best position according
to the screen size. The illustrations show the approximate shortest distance
at maximum zoom. See the following for more information on the
projection distance.
s"Screen Size and Projection Distance" p.119

When you correct keystone distortion, the projected image may be
reduced.
