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.
Caution
Check the positions of the (+) and (-) marks inside the battery holder to
ensure the batteries are inserted the correct way.
c
Replace the battery cover.
Press the battery compartment cover until it clicks into place.

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.
