Variable function keys:
A factory preset is performed which fits your
microscope configuration. The function keys are
labeled accordingly, and a separate description
of the key occupation accompanies the
microscope (“Identification Sheet”).

Abbreations are listed on p.32f.

For each objective, optimal values for the aper-
ture diaphragm and the field diaphragm are al-
ready set. The condenser is also already
adjusted in the factory.

There is a row of function keys both on the right
and left side of the stand. Some of these keys
are defined, and some of them are variable. The
variable function keys have various meanings
depending on the microscope configuration.

The  TL/IL key (38.1) switches between incident
light and transmitted light. The last contrast
method used is restored.
The INT (38.3) keys adjust the light intensity indi-
vidually. Settings can be made either in large or
small increments. Pushing both INT buttons at
the same time switches between coarse and
fine setting. The display indicator changes
accordingly

trast method.
