Maintenance
This section describes maintenance tasks such as cleaning the unit and replacing consumable parts.
Caution
Before starting the maintenance, unplug the power cable from the electrical outlet.
Cleaning
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.
• 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.
• Do not rinse the air filter in water. Do not use detergents or
solvents.
Cleaning the main unit
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.
Cleaning the projection lens
Use a commercially available cloth for cleaning glasses
to gently wipe the lens.
72
Do not use volatile substances such as wax, alcohol, or thinner
to clean the unit's surface. These can cause the unit to warp
and make the coating finish peel off.
Do not rub the lens with harsh materials or subject the lens to
impact shock, as it is fragile.
