Unpacking
The microscope is housed in a moulded Styrofoam container. Remove the tape from the edge of the container
and lift the top half of the container. Take some care to avoid that the optical items (objectives and eyepieces)
fall out and get damaged. Using both hands (one around the arm and one around the base), lift the microscope
from the container and put it on a stable desk.

1. Turn the observation head to a comfortable
position for observation.
2. Ensure that the specimen is centred over
the stage opening. Lock the specimen
slide on the mechanical stage using the
two slide clamps.
3. The microscope comes with an electrical
illuminator. Insert the plug of the external
power supply into the power socket on the
back of the microscope and turn on the light
by using the main switch on the microscope.
On B-50 and B-50B, turn the light control
knob located under the condenser.
4. Rotate the coarse focusing knob to bring
the slide into focus with the 4x objective.
Adjust the fine focusing knob (when
included) to get the image sharp and clear.
5. Turn the nosepiece to choose the objective
you need.
