How do I clean the obstacle sensor?

  • Clean the projector's obstacle and motion sensors glass (circled in red) periodically, or if you see a message telling you to remove any obstacles that are interfering with the projection area.

    • To remove dust or smudges, gently wipe the obstacle sensor glass with lens-cleaning paper.
    • To remove stubborn smudges, moisten a soft, lint-free cloth with lens cleaner and gently wipe the obstacle sensor glass.

      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 canned air, or the gases may leave a flammable residue. Do not use glass cleaner or any harsh materials to clean the obstacle and motion sensors and do not subject them to any impacts. Damage on the surface of the sensors may cause malfunction.
