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.

1. Turn the coarse focusing knob ① until the
nosepiece reaches its lowest position.
► For a safe transport, the nosepiece is
placed in the lowest position and the
tension adjustment collar ②is adjust-
ed to the appropriate tension when the
microscope leaves the factory. (Fig.1)
2. Screw the lowest magnication objective
on to the nosepiece from the right side,
then turn the turret clockwise. Install the
other objectives in the same way, following
the sequence from low to high magnica-
tion.
► Note: the objectives can also be in-
stalled through the stage opening.
(Fig.2)
► Clean the objectives regularly. In inverted
microscopes, the objectives are very sen-
sitive to dust.
► To prevent dust and contamination from
entering the microscope, cover all the un-
used holes with dust caps ③. (Fig.3)
► When operating, use the low magnication
objective (4x or 10X) to search and focus
the specimen, then switch to higher magni-
cations.
► When switching between objectives, slowly
turn the nosepiece until it clicks. The click
means that the objective is in the right posi-
tion, in the center of the light path.

7.1 Installing the objectives
The stage extension can be installed on either
side of the stage to enlarge the working sur-
face. The mechanical stage must be installed
on the right side of the microscope.
1. Installing the stage extension: screw the
bolts on to the extension, then mount the
extension from below the stage. (Fig.4)
2. Installing the mechanical stage: as for the
extension, the mechanical stage is xed
with two bolts under the stage. (Fig.5)

1. When using the stage inserts, make sure
that the insert is horizontal.
2. Install the stage insert in the stage open-
ing. (Fig.6)
7.3 Installing the stage insert
7.4 Installing the eyepieces
Insert both eyepieces into the tubes of the
optical head. (Fig.7)

1. Slide the condenser into the condenser
holder, inserting the pin on the rear side of
the condenser with the alignment groove
in the condenser holder. (Fig. 8)
2. Lock the condenser with the locking knob
① on the right side of the condenser hol-
der. (Fig. 9)

1. Turn the main switch ① to “O”(o󰀨) before
connecting the power cord. (Fig.10)
2. Insert the plug of the provided power
supply into the power socket of the
microscope. (Fig.11)
3. Plug the power cord int the socket of the
power supply (Fig.12)
4. Plug the power cord into the mains socket.
Check for a safe connection.
► Please use the supplied power cord.
If lost or damaged, please refer to
qualied service.
► Connect the power cord to a grounded
power supply only.

Turning on the light source
Connect the power, turn on the main switch ①.
(Fig.13)
Adjusting the brightness
Turn the brightness adjustment knob ②to
increase and decrease the brightness. (Fig.14)
While rotating the brightness adjustment knob,
the LED indicator on the front panel ③ will turn
ON or OFF some segments. (Fig.15)
Adjusting the tension
► The coarse focusing knob ①is pre
adjusted to a tight tension upon
leaving the factory.
If the nosepiece drops down by itself, or the
specimen defocuses while adjusting the ne
focus knob ③, the coarse focus knob ①is too
loose. Turning the tension adjustment collar
② in clockwise direction tightens the coarse
focus tension. Rotate in the opposite direction
to decrease the tension. (Fig.16)
Setting the specimen
► For the best image quality, use asks,
Petri dishes and slides with a 1.2 mm
thickness.
1. Place the proper insert for your specimen
(according to the table on the right) on the
stage, and x it with the stage clip.
2. Turning the X and Y knobs, move the
specimen to the required position. (Move-
ment Range: 120 (width) × 78 (length)
mm).
Moving the specimen
Move the specimen to the desired position by
freehand or by turning the knobs of the me-
chanical stage.
► When switching objectives, take care
not to touch the adaptor plates with
the objectives, as their weight may
damage the front lens.

Dioptric adjustment
1. Put the scale of each eyepiece on the “0”
position. (Fig 17).
2. Using focusing knobs, focus the specimen
with the right eye.
3. Look into the left eyepiece with your left
eye only. If the image is not sharp, use the
dioptric adjustment ring ①to compensate.
► The adjustment range is ±5 diopter. The
number indicated on the adjustment
ring graduation should correspond to
the operator’s dioptric correction.
Adjusting the interpupillary distance
Observing with both eyes, hold the two
eyepiece prism assemblies. Rotate them
around their common axis until the elds of
view coincide.
► The graduation on the interpupillary
distance indicator ②, pointed by the
spot “.” on the eyepiece holder, shows
the distance between the operator’s
eyes. (Fig. 18)
The range of the interpupillary distance is 48-
75mm.
Selecting the light path
Pull the light path selector lever ③ sideways
using your thumb, selecting the light path you
need. (Fig.19)

Using color lters
Selecting the appropriate color lters according
your need. (Fig.20)
You can stack a group of color lters in the lter
holder, if you ensure that they are level and
that the whole thickness is less than 11mm.
Tilting the condenser holder
When a bigger space is needed between
condenser front lens and stage surface, it is
convenient to tilt the condenser. Doing this it is
possible to use the ambient light to illuminate
the specimen. (Fig. 21)
Rotating the illumination pillar
When using big bottles, the illumination pillar
can be rotated out of the light path allowing to
place them on the stage.
Rotate the knob on the right side of the
illumination pillar (Fig. 22) to unlock the
rotation, then swing out the condenser holder
from the light path (Fig. 23).
Once terminated the observation return the
illumination column to its original position and
lock the knob.
