Selected FAQ

Q:
How and when should I clean the obstacle sensor?
A:
Clean the projector's obstacle sensor glass 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. Do not spray any liquid directly on the obstacle sensor glass.
Warning: Do not use a lens cleaner that contains flammable gas. The high heat generated by the projector lamp may cause a fire.

Caution: Do not use canned air, or the gases may leave a residue.
