Only the lens will be replaced for changing the focusable optics. The fixing ring has to be

removed with a suitable objective wrench. After removing the old lens, put in the new one with

the convex side to the front. Fix the lens with a new O-ring and the new fixing ring. On the

inside of this ring is the sticker with the optics data.
