							94 - Cleaning the projector, Cleaning the lens, Cleaning the Air Filter
Maintenance
This section provides explanations on taking care of the projector, replacing consumable items and other maintenance procedures.




 
Cleaning the projector, Cleaning the lens, 
Cleaning the Air Filter
Clean the projector if it becomes soiled or if the quality of the projected images deteriorate. 
Please clean the air filter about every 100 hours of operation.
Switch off the power supply and disconnect the Power Cord prior to cleaning any part of the 
projector. 
Wa r n i n g
·Personnel other than qualified servicemen must never open the projector. Many high-volt-
age parts are contained inside the cover that may cause electric shocks. Contact your dealer 
or your nearest address provided at page 107
 to request internal inspections, repairs, 
adjustments, cleaning and other tasks.
·Exercise caution when handling the Power Plug and Power Connector. Mishandling may 
result in the outbreak of fire and electric shocks. Observe the following when handling the 
Power Plug.
·Do not connect plugs or connectors that have become dirty or have foreign matter adher-
ing to them.
·Ensure that the plugs and connectors are firmly inserted in the relevant sockets as far as 
they will go.
·Never attempt to connect plugs and connectors with wet hands.
Caution
·Never attempt to remove the lamp immediately after use.
Failure to observe this may result in burns or other injuries. Allow the projector to cool 
down for at least sixty minutes after the power supply has been switched off.
·Disconnect the Power Plug and Power Connector from their sockets when carrying out 
maintenance tasks. Failure to observe this may result in electric shocks. 
						

							 Cleaning the projector, Cleaning the lens, Cleaning the Air Filter - 95
Cleaning the projector
·Gently wipe the soiled parts of the projector with a soft cloth. 
·When the soiling is severe, wipe the area with a cloth moistened with a medium-strenth 
cleaning agent diluted with water, and then gently wipe it with a dry cloth. 
Never use wax, Benzene, thinner or other active agents. Failure to observe this may result in 
damage or paint peeling from the casing.
Cleaning the lens
Clean the lens with an air-blower (available on the open market) and special lens cleaning 
paper. The surface of the lens is easily damaged, so exercise extreme caution and avoid using 
anything other than soft materials.
Cleaning the Air Filter
Air ventilation will deteriorate and the internal temperature of the projector will rise if the Air 
Filter becomes blocked with dirt and dust, and this may result in damage.
Ensure that the projector is stood on its end and the Air Filter cleaned with a vacuum cleaner to 
prevent the dirt and dust from penetrating inside.
Point
·If it is no longer possible to remove the dirt from the Air Filter or it begins to crack, it is time 
to replace it. Contact your dealer in this event.
·A replacement air filter is packaged with the replacement lamp. Replace the Air Filter at 
the same time as replacing the lamp.

tain the initial brightness levels and picture quality.
·The replacement message has been set at approximately 2,000 hours of use in order to 
maintain the initial brightness levels and picture quality.
·Although the replacement message is displayed after approximately 2,000 of use, there 
are cases where the individual characteristics of each lamp and other usage conditions
