6. 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.
Do not touch with bare hands optical surfaces such as lenses, lters or glasses. Traces of grease or
other residuals may deteriorate the nal image quality and corrode the optics surface in a short time.

7.6 Assembling the microscope
1. Remove the dust cap from the microscope frame
and from the bottom of the observation head.
2. Insert the optical head above the stand and
tighten the screw. (Fig. 1)
• Hold the head with one hand during the locking in order to avoid that the head falls.
Only for ALC models:
3. Connect the cable of the ALC (Automatic Light Control) system to the socket placed on the observation head and on the back side of the frame. (Fig. 2)
Fig. 1
Fig. 2
4. Insert both eyepieces into the tubes of the optical
head. (Fig. 3)
• For models B-151, B-152, B-153 and B-155:
only one eyepiece is used as these models
are monocular.
5. Insert the power supply jack in the socket placed
at the rear side of the microscope. (Fig. 4)

7.7 Polarizing set (optional)
1. Place the polarizer on the light exit ① at the base
of the microscope. (Fig. 5)
2. Loosen the head xing knob ② and remove the
head from the microscope frame. (Fig. 6)
①

3. Insert the analyzer into the hole inside the frame
③. (Fig. 7)
4. Put back the head into its original position and
lock the xing knob.

8. Use of the microscope
8.1 Light intensity adjustment
Operate on the light intensity adjustment dial to turn
ON / OFF the microscope and to increase / decrease
the illumination voltage ①. (Fig. 8)
8.2 Use of ALC system
1. Adjust the desired brightness through the eyepieces using the light intensity dial (chapter 8.1).
2. Press the ALC button ② to store this setting (Fig.
9). The light on the microscope will turn o for
some seconds, the will turn on again.
• The settings could not be working when the
light intensity is too low or too high. This is
not a defect.
3. Now the system will automatically adapt the
brightness to the eyepieces when an objective is
changed, when the aperture diaphragm is used
or when another specimen is placed on the stage.
4. Pressing the ALC button again, the ALC system
will be disabled.
• When ALC system is active the light intensity
dial is not active.

8.3 Coarse focus tension adjustment
• Adjust the tension using the provided tool.
The coarse knob tension is pre-setted in the factory.
To modify the tension according to personal’s needs,
rotate the ring ③ using the provided tool (Fig. 10).
Clockwise rotation increases the tension. If the tension is too loose, the stage could go lower by itself
or the focus easily lost after ne adjustment. In this
case, rotate the knob in order to increase the tension.
