- 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 lamp may cause a fire.
Caution:
Do not use canned air, or the gases may leave a flammable residue.
