NOTE

5-1. Cleaning the Cabinet

Before carrying out maintenance of your projector, be sure to always check that the projector is turned off and the power plug is
unplugged from the electrical outlet.
• 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.
Do not allow insecticide or other volatile liquid to splash on the cabinet, lens or screen. Also, do not allow any rubber or
NOTE
plastic object to remain in contact with the cabinet for a long time. The coating may deteriorate or peel off.
