Use the T6H/TR6 torx driver to remove the screw at the bottom of the lens cover shroud.

Rotate the lens shroud counterclockwise about 45 degrees, then remove and retain the locking shroud and Torx screw. The shroud should come off easily; if not, gently wiggle it to find the release point.

Remove the four screws on the perimeter of the lens cover with the PH0 driver.

Pull off the lens cover.

Clean or replace the lens cover, then reassemble in reverse order. Avoid leaving fingerprints on the lens or inside the cover, and do not overtighten the screws.
