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 the bulb or fuse.
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
3. Make sure that the input voltage of the microscope matches that of the local power supply.
Using the power supply with the wrong input voltage may cause a short circuit or fire.
4. Using an incorrect bulb, fuse, or power cord may damage the microscope or cause a fire. The
power cord must be grounded reliably.
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 water with a dry cloth.
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 optical parts.
10. Do not touch the lens surfaces with your fingers. Use a brush and special lens-cleaning
solution to keep the lenses clean.
