To clean the objective lens, remove the electro-optical package from the explosion-proof
enclosure. Use facial tissue dipped in rubbing alcohol (Isopropyl 70%). If it is especially dirty, use
a lens cleaning solution. Press softly or the lens may become loose or dislodged. Blow off lint,
and then replace the electro-optical package in the explosion-proof housing.
