How do I clean the projection window?

• Clean the projection window periodically, or whenever you notice dust or smudges on the surface.

  To remove dust or smudges, gently wipe the projection window with lens-cleaning paper.

  Warning: Do not use a lens cleaner that contains flammable gas. The high heat generated by the projector may cause a fire.

  Caution:
  Do not use glass cleaner or any harsh materials to clean the projection window and do not subject the projection window to any impacts; you may damage it.
