Maintenance
This section describes maintenance tasks such as cleaning the proj ector 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 bl ocked with dust and the message
The projector is overheating.  Make sure nothing is blocking
the air vent, and clean or repla ce 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 sm all amount of neutral detergent, and
then firmly wring the cloth dry  before using it to wipe the
projector case. Then wipe the ca se again with a soft, dry cloth.
Cleaning the lens
To clean the lens it is pref erable 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.

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.46
Lamp replacement period
 The message Replace the  lamp. appears on the screen  when projection starts.
 The projected images get darke r 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 replac ement 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.
