1. Warning
This microscope is a scientic precision instrument designed to last for many years with a minimum of
maintenance. It is built to high optical and mechanical standards and to withstand daily use. We remind you
that this manual contains important information on safety and maintenance, and that it must therefore be made
accessible to the instrument users. We decline any responsibility deriving from incorrect instrument use uses
that does not comply with this manual.
2. Symbols and conventions
The following chart is an illustrated glossary of the symbols that are used in this manual.
CAUTION
This symbol indicates a potential risk and alerts you to proceed with caution.
ELECTRICAL SHOCK
This symbol indicates a risk of electrical shock.
3. Safety Information
Avoiding Electrical Shock
Before plugging in the power supply, make sure that the supplying voltage of your region matches with the
operation voltage of the equipment and that the lamp switch is in off position. Users should observe all safety
regulations of the region. The equipment has acquired the CE safety label. However, users have full responsibility
to use this equipment safely. Please follow the guidelines below, and read this manual in its entirety to ensure
safe operation of the unit.
4. Intended use
Standard models
For research and teaching use only. Not intended for any animal or human therapeutic or diagnostic use.
IVD Models
Also for diagnostic use, aimed at obtaining information on the physiological or pathological situation of the
subject.

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 opti-
cal 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.

7.1 Assembling procedure
1. 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.
2. Insert both eyepieces into the tubes of the optical
head. (Fig. 2)
3. Screw each objective into the thread of
the nosepiece, clockwise with increasing
magnication. (Fig. 3)
4. Insert the power supply jack in the connector
placed at the rear side of the microscope. (Fig. 4)

• The microscope is delivered with two
condensers: one for brighteld and one for
darkeld. Select the suitable condenser for
the observation mode desired.
5. Lower the condenser holder using the height
condenser knob ①. (Fig. 5)
6. Insert the condenser round dovetail in the
condenser holder. (Fig. 6)
7. Tight the condenser locking screw ②. (Fig. 7)
8. (Only for darkeld condenser)
Connect the condenser jack to the connector on
the right side of the frame. (Fig. 8)
• When the condenser plug is connected, the
light coming from the microscope LED goes
out and the internal condenser LED turns on.

(Fig. 9)
• It may take a little bit of force to unscrew the
lens.
2. Fully screw the eld diaphragm (M-156).
3. System is ready for the use.
