Maintenance
To maintain optimum performance and minimize wear, clean this product frequently.
Usage and environment are contributing factors in determining the cleaning frequency.
As a rule, clean this product at least twice a month. Dust build-up reduces light output
performance and can cause overheating. This can lead to reduced light source life and
increased mechanical wear.
To clean a product, follow the recommendations below:
• Unplug the unit from power.
• Wait until the unit has cooled.
• Use a vacuum (or dry compressed air) and a soft brush to remove dust collected on
the external vents and accessible internal components.
• Clean all external optics and plastic surfaces with a mild solution of non-ammonia
glass cleaner or isopropyl alcohol.
• Apply the solution directly to a soft, lint-free cotton cloth or a lens cleaning tissue.
• Wipe any dirt or grime to the outside edge of the lens surface.
• Gently polish the lens surfaces until they are free of haze and lint.
Always dry the external optics and plastic surfaces carefully after cleaning them.
Refrain from spinning this product’s fan using compressed air.
