InstallationSetting Up the Projector
The projector supports the following four different projection methods, 
allowing you to choose the best method for displaying your images.
* A special method of installation is required for suspending the projector 
from a ceiling. Please contact your supplier if you would like to use this 
installation method. The optional ceiling mount is required when 
installing the projector on a ceiling. sp.66
 Before setting up the projector, make sure you read the 
separate SafetyInstructions/World-Wide Warranty 
Terms first.
 Do not set this projector up on its side to carry out 
projection,otherwise malfunctions may occur.
 Front projection (Front projection)
 Rear projection using a translucent screen (Rear projection)
When using ceiling projection or projection using a 
translucent screen, set the Projection command in the 
Extended menu to match the installation method.

MaintenanceThis section describes maintenance tasks such as cleaning the projector and 
replacing consumable parts.Cleaning
You should clean the projector if it becomes dirty or if the quality of 
projected images starts to deteriorate.
Clean the projectors surface by wiping it gently with a soft cloth.
If the projector is particularly dirty, moisten the cloth with water 
containing a small amount of neutral detergent, and then firmly wring the 
cloth dry before using it to wipe the projectors surface. Then wipe it again 
with a soft, dry cloth.
Use a commercially-available air blower, or use a lens cleaning paper to 
gently wipe the lens.If dust collects on the air filter or the air outlet, it can cause the internal 
temperature of the projector to rise, and this can lead to problems with 
operation and shortening of the optical engines service life.
It is recommended that you clean these parts at least once every three 
months. Clean them more often than this if using the projector in 
particularly dusty environments.
Make sure you read the separate Safety Instructions/
World-Wide Warranty Terms before cleaning.
Cleaning the Projectors Surface
Do not use volatile substances such as wax, alcohol or 
thinner to clean the projectors surface. These can 
cause the projector to warp and make the coating finish 
peel off.
Cleaning the Lens
Do not rub the lens with harsh materials or subject the 
lens to shocks, as it can easily become damaged.
Cleaning the Air Filters and Air Intake Vent
If the air filters are broken or if the warning message 
reappears after they have been cleaned, they should be 
replaced. Replace with a new air filter. See Replacing 
the Air Filter. sp.62 
						

							57
MaintenanceReplacing Consumables
This section explains how to replace the remote control batteries, the lamp, 
and the air filters.
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. Replace the batteries. Have two spare AAA-
size alkali batteries ready to use when required.PROCEDUREA
Remove the battery cover.
While pushing the catch of the battery compartment cover, lift 
the cover up. 
B
Insert the batteries.
Check the positions of the (+) and (–) marks inside the battery 
holder to ensure that the batteries are inserted the correct way.
C
Replace the battery cover.
Press the battery compartment cover until it clicks into place.
Replacing the batteries
Make sure you read the Safety Instructions/World-Wide 
Warranty Terms before handling the batteries.

Maintenance
It is time to replace the lamp when:
 The message Replace the Lamp. appears on the screen when 
projection starts
. When the Lamp indicator is flashing orange
 The projected image gets darker or starts to deteriorateLamp Replacement Period
A message will be displayed.
Flashing orange
 The lamp replacement message is set to appear after the 
following periods of time in order to maintain the initial 
brightness and quality of the projected images. 
Brightness Control sp.35
· When used continuously at high brightness: Approx. 
1900 hours
· When used continuously at low brightness: Approx. 
2900 hours
 If you continue to use the lamp after this period, the 
possibility of the lamp breaking becomes greater. When 
the lamp replacement message appears, replace the 
lamp with a new one as soon as possible, even if it is still 
working.
 Depending on the characteristics of the lamp and on 
the way it has been used, the lamp may become darker 
or stop working before the lamp warning message 
appears. You should always have a spare lamp ready in 
case it is needed.
 Contact your dealer for a spare lamp.
Replacing the Lamp
 If you are replacing the lamp because it has stopped 
working, it is possible that the lamp is broken.
If replacing the lamp of a projector which has been 
installed on a ceiling, you should always assume that 
the lamp is broken and be extremely careful when 
removing the lamp cover.
 Wait until the lamp has cooled down sufficiently before 
removing the lamp cover. To give the lamp enough time 
to cool down after turning off the power, wait for about 
one hour.

Maintenance
PROCEDUREA
After you turn off the projector’s power, and the 
confirmation buzzer beeps twice, disconnect the 
power cable.
B
Wait until the lamp has cooled down, then remove the 
lamp cover from the base of the projector.
Loosen the lamp cover fixing screw with the screwdriver that is 
supplied with the spare lamp (or your own cross head 
screwdriver).
Then slide the lamp cover straight forward and lift it to remove.
C
Loosen the two lamp fixing screws.
Loosen the two lamp fixing screws with the screwdriver that is 
supplied with the spare lamp (or your own cross head 
screwdriver).
D
Take out the lamp.
Hold the lamp as shown in the illustration below and lift it up 
and out of the projector.
If the lamp is broken replace it with a new lamp, or contact your 
local dealer for further advice. If replacing the lamp yourself, 
be careful to avoid pieces of broken glass.
