Olympus 35-S rangefinder adjustment

I’m a visual person so I think that a picture is often the best way to explain something.  This is the cover for the rangefinder adjustment for the Olympus 35-S.  Once this cover is removed you can insert a suitable slotted screwdriver and gently turn the screw until the rangefinder image merges with the rest of the scene when the lens is set to infinity.  So when done an object at infinity should match giving a single image within the rangefinder patch.
