User Maintenance Cleaning the Projector Periodically clean the projector exterior, lens, intake vents, and exhaust vents on a regular basis. Cleaning Intake and Exhaust Vents Dust and dirt tend to collect around the intake vents. Because of this, you should use a vacuum cleaner to clean away accumulated dust and dirt periodically. Important! Continued use of the projector after dust has accumulated around the intake vents can cause overheating of internal components and lead to malfunction. Certain operating conditions also can cause dirt and dust to accumulate around the projector's exhaust vents on the front. If this happens, use the same procedure as that described above to clean the exhaust vents. About the Light Source Unit Should the light source unit stop working, contact your original dealer or authorized CASIO service center for replacement. Note that problems caused by unauthorized projector disassembly or modification are not covered by the warranty and are not eligible for repair by CASIO.
