room approximately one hour before it is to be used. If 
condensation forms on the lens, turn the power off and wait for the 
condensation to disappear.

Maintenance
This 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.
Cleaning the air filter
If the air filter becomes blocked with dust and the message
The projector is overheating. Make sure nothing is blocking
the air vent, and clean or replace the air filter is displayed,
clean the air filter.
Turn the projector upside-down and use a vacuum cleaner to
clean the air filter
Cleaning the projector case
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.
Cleaning the lens
To clean the lens it is preferable to use an air blower
purchased for the purpose. But alternatively you can wipe it
gently clean with a spectacle-cleaning cloth.
Be sure to read the separate Safety Instructions/World-Wide Warranty Terms booklet for details 
on safe handling of the projector during cleaning.
If the air filter becomes clogged with dust, it can result 
in overheating which may cause operating problems or 
reduce the operating life of the optical parts. It is 
recommended that you clean the air filter about once 
every three month. If using the projector in a dusty 
location, the air filter should be cleaned more often.
Do not use volatile substances such as wax, alcohol or 
thinner to clean the projector case. These can cause 
the case to warp and make the coating finish peel off.
Do not rub the lens with harsh materials or subject the 
lens to shocks, as it can easily become damaged.

Maintenance
Appendix
Consumable replacement periods
Air filter replacement period
 If the air filter has been broken or the Replace message is displayed even though the
air filter has been cleaned.
Replace with an optional air filter. 
Replacing the air filter p.44
Lamp replacement period
 The message Replace the lamp. appears on the screen when projection starts.
 The projected images get darker or start to deteriorate.
•The replacement warning message is set to appear after a minimum of about 1600 
hours of lamp use in order to maintain the initial brightness and quality of the 
projected images. The time taken for the message to appear will vary depending on 
usage conditions such as Color Mode settings.
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.
A message will be displayed.
