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 alkaline or manganese batteries ready. You
cannot use other batteries except for the AA size alkaline or manganese.
Attention
Make sure you read the following manual before handling the batteries.
sSafety Instructions

Make sure you fix the lens unit removal button with the screw to
prevent the lens unit from being stolen.
Attention
•Store the projector with the lens unit installed.
If the projector is stored without the lens unit, dust and dirt may get inside
the projector and cause malfunctions or lower the quality of projection.
•When the projector is facing up (35 to 150 degrees) or down (-35 to -150
degrees), tighten the lens torque ring. Note that it could malfunction if it is
over tightened.
Removing
Attention
•Only remove the lens unit when necessary. If dust or dirt enter the projector,
projection quality deteriorates and it could cause a malfunction.
•Try not to touch the lens section with your hand or fingers. If fingerprints or
oils are left on the surface of the lens, projection quality deteriorates.
•If the lens shift has been done, set the lens shift to the center before replacing
the lens unit.

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

Installation Requirements
The projector can be mounted on a ceiling or placed on a desk. Also, it can
be mounted at a tilted angle, so you can flexibly project images to various
places.
Warning
•A special method of installation is required when suspending the projector
from a ceiling (ceiling mount). If installation work is not carried out
correctly, the projector could fall down. This may result in injury or
accidents.
Contact your dealer or the nearest address provided in the Support and
Service Guide if you want to use this installation method. sEpson Projector
Contact List
•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.
•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.156
•When mounted on a ceiling, set Inv Direction Button to On so that
the operations and movement of the [ ], [ ], [ ], and [ ]
buttons on the control panel match.
