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
operation voltage of the equipment and that the lamp switch is in o󰀨 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.

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.

7.4 Assembling the microscope
7.4.1 B-292 / B-292PLI / B-293 / B-293PLI
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 lo-
cking 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 trinocular head
Unscrew the protection cap mounted on the photo
port and screw the photo tube. (Fig. 4)
