2) Move the "NCB11 filter" on the dia-illuminator into the
optical path.
3) Move the "ND4 filter" on the dia-illuminator into the optical
path.
4. Adjust the optical path.
1) Move the < 10X > objective into the optical path.
2) Set the "optical path switchover dial" on the right side of the
microscope to position < 1 >. (-> Direct 100% light to the
observation port.)
3) Raise the "field diaphragm lever" on the dia-illuminator
completely to open the field diaphragm fully.
