2. Unpacking and assembly
The microscope is packed in a molded
styrofoam 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 temper-
ature.
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 objectives will be found within individual
protective vials. Install the objectives into the
microscope nosepiece from the lowest mag-
nification to the highest, in a clockwise direc-
tion from the rear.
Insert the eyepiece into the tube and secure
it in place using the small hex key.
Secure the head with the large hex key.

3. Operation
3.1 General information
Set the microscope on a level table.
Place the object to be observed in the center
of the object plate.
Connect the mains cable to the net and turn
on the switch to get the object illuminated.
Make certain that the specimen is centered
over the opening in the stage.
Make the necessary eyepiece dioptre ad-
justments to suit your eyes (refer to 3.2).
Adjust the interpupillary distance so that one
circle of light can be seen (refer to 3.3).
Adjust the aperture of the iris diaphragm to
get the background brightness suitable for a
high contrast image.
Rotate the nosepiece until the objective with
the lowest magnification is pointed at the
specimen. There is a definite "click" when
each objective is lined up properly.
NOTE: It is best to begin with the lowest power
objective. This is important to reveal general
structural details with the largest field of view
first. Than you may increase the magnification
as needed to reveal small details.
