Maintenance
Dust build-
up reduces light output performance and can cause overheating. This can
lead to reduction of the light source’s life and mechanical wear.
To maintain optimum
performance and minimize wear, clean the product at least twice a month. However,
usage and environmental conditions contribute to increased cleaning frequency.
To clean the product, follow the instructions below:
1. Unplug the product from power.
2. Wait until the product is at room temperature.
3. Use a vacuum (or dry compressed air) and a soft brush to remove dust
collected on the external surface.
4. Clean all external optics and transparent surfaces with a mild soap solution,
ammonia-free glass cleaner, or isopropyl alcohol.
5. Apply the solution directly to a soft, lint-free cotton cloth or a lens cleaning
tissue.
6. Softly wipe any dirt or grime to the outside edges of the external optics or
transparent surface.
7. Gently polish the external optics and transparent surfaces until they are free of
haze and lint.
Always dry the external optics and transparent sur
faces carefully after cleaning
them.
