Cleaning the projector lens
If there is any dust or staining on the lens surface, you must clean the lens.
Use an air spray or a cleaning cloth to clean the lens.
To remove dust or stains, use an air spray or apply a small amount of cleaning agent onto a swab or soft
cloth to clean the lens. Please be aware that liquid may flow into the lens if the product is sprayed directly
onto the lens.
Cleaning the projector case
Cleaning the air vents
To clean the projector case, first unplug the power cord.
Do not use alcohol, benzene, thinners or other chemicals which may damage the case.
Check the air vents for dust or contaminants often and remove them, as it is easy for them to accumulate. If
you continue to use the projector without removing these materials, the projector may not work properly due
to its internal components overheating.
* Clean the case, lens, suction ports and exhaust vents of the projector periodically.
If dust or stains accumulate on the projector, it may appear on the screen, or the screen may appear darker. Cleaning is there-
fore very important.
If replacement parts are required, contact your seller or an LG Electronics Service Center.
To clean the parts of a projector, turn off the projector and pull the plug from the power outlet.
Clean the projector more often if it is used for commercial purposes or it is used in a dusty environment.
