7. Maintenance
NOTE
• Please request your distributor to perform cleaning of the projector inside.
❶
Cleaning the Cabinet
WARNING
• Please do not use a spray containing flammable gas to remove dust attached to the cabinet, etc. Doing so may
result in fires.
Be sure to always check that the AC power supply of the projector is disconnected before carrying out maintenance
of the projector.
• Wipe with a dry, soft cloth without nap.
When the cabinet is excessively dirty, wipe with cloth well wrung after being dampened with a neutral detergent
diluted with water and then finish up with a dry cloth.
When you use a chemical dust cloth, follow the instructions in the manual attached to it.
• Do not use a solvent, such as thinner or benzene. The coating may deteriorate or peel off.
• When removing dust on the ventilation opening, suck it off using an adapter with a brush on a vacuum cleaner.
Never allow the cleaner without an adapter to come into direct contact or use a nozzles adapter in cleaning.
• Clean the ventilation opening at regular intervals. Dust, if allowed to accumulate there, may cause heating inside,
which leads to functional trouble. The interval, which can vary with the location of your projector, is about 100 hours.
• Do not damage the cabinet by scratching it or allowing hard objects to hit it. This can scratch the projector.
• Consult your dealer/distributor about cleaning the inside of the projector.
NOTE
• Do not allow insecticide or other volatile liquid to splash on the cabinet, lens or screen. Also, do not allow any rubber or plastic
object to remain in contact with the cabinet for a long time. The coating may deteriorate or peel off.
❷
Cleaning the Lens
Clean the lens the same way as with camera lens (using a commercially available camera blower or cleaning paper
for glasses). Take care not to damage the lens when cleaning.
WARNING
• Do not look into the light source while the projector is ON. Strong light is emitted from the projector and visual
impairment could result.
• Please do not use a spray containing flammable gas to remove dust attached to the lens, etc. Doing so may
result in fires.
CAUTION
• Before cleaning the lens, first turn off the power, make sure the cooling fan has completely stopped, then turn
off the AC power. Make sure the unit has cooled down completely before cleaning the lens.
