1. Warning
This microscope is a scientic 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 ope-
ration voltage of the equipment and that the lamp switch is in off position. Users should observe all safety regu-
lations 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 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. Assembling
Once opened the box, the microscope parts are the following:
① Microscope body
② Eyepieces
③ Objectives
④ Stage metal insert
⑤ Lamp housing
⑥ Color lters (LBD and IF550)
⑦ Analyzer
⑧ Polarizer
⑨ Filter holder

7.1 Microscope assembling
7.1.1 Installing the objectives
1. Rotate the coarse focusing knob ① until the nose-
piece reaches its lowest position. (Fig. 1)
• For a safe transport, the nosepiece is placed
in the lowest position before shipment from
the factory.
2. Screw the lowest magnication objective on to
the turret from the right side, then turn the nose-
piece clockwise. Mount the other objectives in
the same way, following the sequence from low
to high magnication. (Fig. 2)
• Clean the objectives regularly. In inverted mi-
croscopes, the objectives are very sensitive
to dust.
• To prevent dust and dirt from entering the
microscope, cover all the unused holes with
dust caps ②. (Fig.3)
7.1.2 Installing the stage insert
1. Install the stage insert in the stage opening. (Fig.
4)

7.1.3 Installing the eyepieces
1. Insert both eyepieces into the tubes of the optical
head. (Fig. 5)
7.1.4 Installing the lamp housing
1. Insert the lamp house and tighten the xing
screws ①. (Fig. 6)
7.1.5 Installingthelterholder
• The microscope is equipped with a lter holder
located on the back side of the microscope. (Fig.
7).
• The lter holder has three positions: ② lter
holder for color lters, ③frosted lter, ④ lter
holder for color lters.
1. Remove one of the knobs ⑤ from the lter holder.

2. Insert the lter holder into the slot in front of the
lamp housing ⑥. (Fig. 9)
3. When the filter holder is in place, reinstall the filter
holder knob.
7.1.6 Installing the bulb
1. Open the lamp housing cover. (Fig. 10)
2. Insert the halogen bulb into its holder ⑦. (Fig. 11)
• Do NOT touch the bulb with the bare hands,
this could reduce the bulb efciency and
lifetime.
3. Plug the power cable from the lamp housing to
the microscope body. (Fig. 12)

7.1.7 Connecting the power cord
1. Put the main switch ① to “O” (OFF) before con-
necting the power cord. (Fig.13)
2. Insert the cable into the power socket of the mi-
croscope. (Fig.14)
3. Plug the power cord into the mains socket. Check
for a safe connection.
• Please use the provided power cord.
• If lost or damaged, please refer to qualied
service.
• Connect the power cord to a grounded power
supply only.
7.1.8 Replacing the fuse
• Before replacing the fuse, turn the main switch to
“O” (OFF) and unplug the power cord.
1. Rotate the fuse support out of the holder using a
straight screwdriver. Insert a new fuse in the sup-
port, then rotate the support back into the holder.
(Fig.15)
• Fuse rating: see back of the microscope.

7.1.9 Installing mechanical stage or stage extension
• Stage extension and mechanical stage are op-
tional accessories.
• Stage extension can be installed on either side of
the stage to enlarge the working surface.
• Mechanical stage can only be installed on the
right side of the stage.
1. Screw the bolts in the xing holes of the attach-
ments, then mount the unit from below the stage.

7.1.10 Installing polarizer and analyzer
1. Insert the polarizer “S-PO” into the slot ① placed
on the left side of the lamp housing support. (Fig.
17)
2. Insert the analyzer “S-ANR” in the slot ② placed
on the right side of the microscope body. (Fig. 18)
