Before Using the Remote Control
Inserting the Batteries
The batteries are not inserted into the remote control at the time of purchase, 
and so you need to insert them before the remote control can be used.
Procedure
1Remove the battery compartment 
cover.
While pushing the catch of the battery 
compartment cover, lift the cover up to 
remove it.
2Insert the batteries.
Make sure the polarities of the batteries 
are correct.
3Replace the battery compartment 
cover.
Press the battery compartment cover 
until it clicks into place.
Battery Replacement Period and Cautions
If the remote control becomes slow in responding or if it stops working, the 
batteries may be spent. If this happens, replace the batteries with fresh ones.
* The replacement period given above may vary depending on the amount of 
usage and the ambient conditions.
Use the following type of batteries as replacements.
2 AA manganese batteries
Guide to battery replacement period: After about 6 months if the remote control is 
used for 30 minutes each day

Using the Remote Control and Remote Operating Range
The remote control is used in the following way.
Procedure
1Set the R/C switch on the remote 
control to the ON position.
2Point the remote control 
transmitter toward one of the 
remote control receivers on the 
projector and operate the remote 
control buttons.
Tip :
• Do not allow sunlight or light from fluorescent lamps to shine directly onto the 
projectors remote control receivers, otherwise it may interfere with the reception of 
signals from the remote control.
 Set the R/C switch on the remote control to the OFF position when not using the remote 
control. Leaving the R/C switch on will consume battery power.
Use the remote control within the ranges indicated below. If the distance or 
angle between the remote control and the remote control receiver is outside the 
normal operating range, the remote control may not work.

Notes on Handling the Remote Control
Make sure that you observe the following at all times to avoid malfunctions or 
damage to the remote control.
Do not drop the remote control or subject it to strong shocks.
Do not allow the remote control to become wet. If it does become wet, 
wipe it immediately with a dry cloth.

Installation
Setting Up the Projector
The projector supports the following four different projection methods, 
allowing you to choose the best method for displaying your images.
When setting up the projector, be sure to first read the Safety Instructions/
World-Wide Warranty Terms for information on the safety precautions 
that must be observed at this time.
Front projection
Front/ceiling projection
* A special method of installation is required in order to suspend the projector 
from the ceiling. Please contact the place of purchase if you would like to use 
this installation method.

* A special method of installation is required in order to suspend the projector 
from the ceiling. Please contact the place of purchase if you would like to use 
this installation method.

Screen Size and Projection Distance
The distance between the projector and the screen determines the actual image 
size.
While referring to the table below, position the projector so that the image size 
is smaller than the screen size.
* The value for the projection distance should be used as a guide for setting up 
the projector. The actual distance will vary depending on projection conditions.
Tip :
 The projector’s lens allows a zoom ratio of up to about 1.35. The image size at the 
maximum zoom setting is about 1.35 times bigger than the image size at the minimum 
zoom setting.
 The image size will be reduced when keystone correction is carried out.Recommended distance0.9m – 12.4m (3.0 – 40.7 ft.)
