1. Warning
This microscope is a scientic precision instrument designed to last for many years with a minimum of mainte-
nance. 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 acces-
sible 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 responsibil-
ity to use this equipment safely. Please follow the guidelines below, and read this manual in its entirety to ensure
safe operation of the unit.

5. 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.
6. Assembling
Once you open the box, these are the microscope’s components:
① Condenser
② Optical head
③ Main body
④ Eyepieces
⑤ Power supply

Insert the condenser under
the stage: position until it is
well inserted into its holder
(under the condenser there is
a pin that must fully enter the
guide of the holder). (Fig. 3)
AFTER INSERTING THE
CONDENSER, TIGHTEN
THIS SCREW
Put the microscope stand on a
solid table. Insert the optical
head above the attachment,
using the 2mm Allen wrench
to tighten the screw. (Fig.1)
Insert both eyepieces into
the tubes of the optical head.

8. Using the microscope
In order to activate the transmitted light illu-
minator, insert the plug of the external power
supply into the socket and turn on the main
switch on the side of the main body. Turn the
brightness adjustment knob to a brightness
suitable for observation. (Fig.6)
Loosen the lock-screw, turn the observation
head to a comfortable position for observation,
and then lock the lock-screw. (Fig.7)

1. Look into the right eyepiece with your right
eye only, and focus on the specimen.
2. Look into the left eyepiece with your
left eye only. If the image is not sharp,
use the dioptric adjustment ring ①to
compensate. (Fig.8)
► The adjustment range is ±5 diopter. The
number indicated on the adjustment
ring graduation should correspond to
the operator’s dioptric correction.

Stage
Stage accepts standard slides 26 x 76 mm,
thickness 1,2 mm with coverlside 0,17mm.
It is possible to place two slides side by side
on the stage.
• Open the spring arm of the slide
holder and place frontally the slides
on the stage.
• Gently release the spring arm of the
slide holder. (Fig. 12)
► A sudden release of the the spring
arm could cause the falling of the
slide.

Observing with both eyes, hold the two
eyepiece prism assemblies. Rotate them
around their common axis until the elds of
view coincide. (Fig.9)

• Use with eyeglasses (Fig. 10)
Fold rubber eyeshields with both hands.
Folded eyeshields avoid scratching the
lenses of eyeglasses.
• Use without eyeglasses (Fig. 11)
Raise eye shields and observe at the
microscope placing eyes to the shields,
avoiding external light to disturb the
observation.
