Before using the microscope, please read this user manual carefully to
study the instrument design, operation modes and procedures, operational
limitations, and safety precautions.
Due to the continuous improvements in the microscope design, this manual
may not reflect minor design changes that do not affect the microscope
performance and operation procedures.
1. To avoid electric shock or fire, switch off and unplug the microscope before assembling the microscope, replacing
2. Do not disassemble the microscope, except for the removable parts specified in this manual. This can seriously
damage its performance. In case of malfunction, please contact a qualified service center.
3. Make sure that the input voltage of the microscope matches that of the local power supply. Using the power supply

4. Using an incorrect bulb, fuse, or power cord may damage the microscope or cause a fire. The power cord must be
5. In order to avoid a short circuit or any other malfunction, do not expose the microscope to high temperatures or
humid or moist environments for a long period of time.
6. If water splashes on the microscope, immediately switch the power off, unplug the power cord, and wipe off the
7. The microscope light bulb generates high temperatures during operation. To avoid burns, do not touch the collector
lens or the bulb itself for 10 minutes after the lights have been switched off. To prevent fire, do not place paper or
flammable or explosive materials near the air vents on the underside of the base.
8. The microscope employs a coaxial coarse/fine focusing mechanism. Do not turn the left/right coarse/fine focusing
knobs in opposite directions. When the limit is reached, you should no longer rotate the coarse focusing knob.
9. Do not expose the microscope to direct sunlight or other light sources. Do not expose the microscope to high
temperatures, humidity, or dust; otherwise, it may cause condensation, mold growth, or contamination of the
10. Do not use any other oily substance instead of proper immersion oil made specifically for the given purpose, as this
will degrade the image quality and damage the lenses.
11. Do not touch the lens surfaces with your fingers. Use a brush and special lens-cleaning solution to keep the lenses
