The aperture is controlled using the arrow buttons.

The Prev. and Max. buttons reset the stops to the
previous and maximum values respectively.
If a motorized FL attenuator is fitted, it cannot be
set via the TFT display. The lower aperture
diaphragm display is then not available.

positions may change -
contrast adjustment). If the contrast technique is not available for the
objective, the system will switch to brightfield.
