3. Unpacking and assembly
The microscope is packed in a molded styro-
foam container.
•
Take the container out of the carton remove
the tape and carefully lift the top half off the
container. Be careful not to let the optical
items (objectives and eyepieces) drop down.
•
To avoid condensation on the optical com-
ponents, leave the microscope in the original
packing to allow it to adjust to room tem-
perature.
•
Using both hands (one around the pillar and
one around the base), lift the microscope
from the container and put it on a stable
desk.
The microscope is fully assembled except for
the eye-shields. Position them over the eye-
pieces for viewing comfort and to block out any
ambient light. In addition, the object plate must
be inserted into the stage opening in the base.
Please note that you must remove the protective
paper.

•
Adjust the interpupillary distance between
the eyepieces by grasping the two prism-
