Note:
When replacing objectives, you must perform a
teach-in for the new objectives in the Leica Ap-
plication Suite (LAS). A parfocality teach-in
should also be performed.
Note:
For lockable immersion objectives lock these by
pushing the front part upwards until it stops
(approx. 2 mm). Then, after a gentle turning mo-
tion to the right, the objective is locked.
For objectives with corrective mounts turn the
knurl to adjust the objective to the thickness of
the cover glass.
