This section describes maintenance tasks such as cleaning the unit and replacing consumable parts.
Cleaning the air filter and air 
intake vent
When dust builds up on the air filter or the air intake 
vent, or the message “The unit is overheating. Make sure 
nothing is blocking the air vent, and clean or replace the 
air filter.” is displayed, remove any dust from the air 
filter and the air intake vent using a vacuum cleaner.
Cleaning the main unit
Cleaning the projection lens
Maintenance
Caution
Before starting the maintenance, unplug the power cable from the electrical outlet.
If dust collects on the air filter or the air intake vent it can 
cause the internal temperature of the unit to rise, and this can 
lead to operation problems and a shortening of the service 
life of optical parts. It is recommended that you clean these 
parts at least once every three months. Clean them more 
often than this if the unit is used in particularly dusty 
environments.
Clean the surface by wiping it gently with a soft cloth.
If the unit is particularly dirty, moisten a cloth with 
water containing a small amount of neutral detergent, 
firmly wring the cloth dry, wipe the unit softly with the 
cloth to remove stains, and then wipe it again with a 
soft, dry cloth.
Do not use volatile substances such as wax, alcohol, or thinner 
to clean the units surface. These can cause the unit to warp 
and make the coating finish peel off.
Use a commercially available cloth for cleaning glasses 
to gently wipe the lens.
Do not rub the lens with harsh materials or subject the lens to 
impact shock, as it is fragile.
