How and when should I clean the obstacle sensor?
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.
Caution: Do not use canned air, or the gases may leave a residue.
