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 projector case 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 projector case. Then wipe the case 
again with a soft, dry cloth.
Use a commercially-available air blower, or use lens cleaning paper to 
clean the lens.If the air filters become clogged with dust, or if the message The projector 
is overheated. Clean or replace the air filter and lower the room 
temperature. appears on the screen, clean the air filters and the air intake 
vent.
If the air filters become clogged with dust, it can cause overheating and 
damage the projector.

							124
Maintenance Maintenance
PROCEDURE
Turn the projectors power off, wait for the cool-down 
period to end, and then disconnect the power cable.
The cool-down period lasts for about 30 seconds.
TIP
 The replacement warning message is set to appear after about 1900 
hours of lamp use in order to maintain the initial brightness and 
quality of the projected images. 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.
 The warning message appears after about 1900 hours of use, but the 
actual life of each individual lamp will vary depending on the 
characteristics of the lamp and on the way it has been used, and 
some lamps may stop operating before 1900 hours of use. You should 
always have a spare lamp ready in case it is needed.
 Contact your dealer for a spare lamp.
Replacing the Lamp
CAUTION
 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 to the 
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. It takes a further one hour after the cool-down
period 
has finished for the lamp to be cool enough.

TIP
If the projector has been installed on the ceiling and the cable cover 
has been attached, remove the cable cover before proceeding.   p.34

Insert the cover tab at the top of the lamp cover into the 
projector, and then install the lamp cover and tighten the two 
lamp cover fixing screws.
The projector has a built-in counter which keeps track of the lamp

certain point, it causes the replacement warning message to be displayed. 
Therefore, the counter needs to be reset using the configuration menu after 
the lamp has been replaced with a new one.

Resetting the Lamp Operating Time
TIP
 Install the lamp securely. If the lamp cover is removed, the lamp turns 
of automatically as a safety precaution. Moreover, the lamp will not 
turn on if the lamp or the lamp cover is not installed correctly.

also be replaced when the lamp is replaced.   p.127
 Dispose of used lamps properly in accordance with your local
