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:

7.3 Assembling the microscope
7.3.1 B-190 Series
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.
3. Insert both eyepieces into the tubes of the optical head.
(Fig. 2)
4. Insert the power supply jack in the socket placed at the
rear side of the microscope. (Fig. 3)
Only for B-193
5. Unscrew the protection cap mounted on the photo port
and screw the photo tube. (Fig. 4)

7.3.2 B-190TB
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. 5)
• Hold the head with one hand during the locking in
order to avoid that the head falls.
3. Insert both eyepieces into the tubes of the optical head.
(Fig. 6)
4. Insert the power supply jack in the socket placed at the
rear side of the microscope. (Fig. 3)
5. Fix the rotating part of the junction using the black wing-
nut ①. (Fig. 7)
6. Then hook the Tablet PC onto the 4 screws of the junc-
tion and pull toward down to rmly lock the Tablet PC in
the holder. (Fig. 8)
• To unlock the Tablet PC proceed with the opposite op-
eration: push toward up and remove it from the holder.

7. Plug one side of the cable named CAMERA CONNEC-
TION (USB + OTG) ②to the digital head and the oth-
er side to the Tablet PC using the connector ③. (Fig.
9-10).
8. Plug the cable named POWER SUPPLY CONNEC-
TION to the Tablet PC for battery recharge using the
connector ④. (Fig. 10)
• The connector ④has a label on the back side of the
Tablet PC ⑤(Fig. 11). This connector is used for
battery recharge and for camera connection.
• The connector ③is used ONLY for the camera
connection.
• DO NOT use the connector ③for battery recharge.
This could cause malfunctions / damages.
• The Tablet has been set with the Rotation function dis-
abled: this prevents any ipping of the Live View in or-
der to get a continuous and as large as possible view
of your slide also when the Tablet is removed from the
holder.
• To enable this function again: you can activate the Ro-
tation by swiping the screen on his bottom right side
and selecting Settings + Screen. Anyway, it’s not sug-
gested to activate the function when the camera is in
Live View mode as it may give troubles when the cam-
era runs at high resolutions.
