Key for defining the “lower Z position”. Pressing the key for longer than 1 sec. deletes the threshold; another press of the key for longer than 1 sec. sets the current Z position as “lower threshold”.

Key for defining the “upper Z threshold” (= focus position). Pressing the key for longer than 1 sec. deletes the threshold, another press of the key for longer than 1 sec. sets the current Z position as “upper Z threshold”.

!n. b.:

If using the microscope without the stage plate, please note that when you replace the front fixing screw if the stage plate, it must not be screwed in fully. If it is screwed in too far it will block the focus motor. The message BLK then appears in the LC display on the front of the microscope.

Coded IC objective prisms (option)

The objective IC prisms are arranged on a turret underneath the objective nosepiece. To facili- tate allocation and thus the setting of the objective prisms to the objectives, the LC display on the front of the microscope indicates both the IC prism required for the objective in the light path and the currently effective IC prism on the turret.

The latter flashes if the combination is wrong.
