ATTENTIONS
1. Please handle the microscope carefully.
•Following the Figure-2 step to move the instrument, make sure the sample is taken
away. Use one hand holding ① position, the other hand holding ② position.
•If rising microscope’s height with other parts, must keep it in horizontal position,
prevent incline and sample slip.
Figure-1 Replace Bulb
2. Before replacing the lamp, first turn off power switch at off position O, and unplug
it in case of electric shock and burn. The power supply must be cut off before bulb
replacement. If microscope is in use or after use, the bulb and lamp house must be
cooled off completely before proceeding, please see Figure-1, Loosening screw 1,
pulling out lamp shade 2, and replace broken bulb with required bulb 3.
3. Microscope must be placed on stable and horizontal table.
4. Only use our power cord, wrong power cord can’t guarantee instrument safety and
performance.
5. Keep enough space between power cord and lamp house, if power cord touch lamp socket,
will result in fuse melt or electric leakage.
6. The microscope ground terminal must be tightly connected with plug’s ground terminal.
7. If unexpected situation happens, please pull the plug out.
8. Disassembly only by the professionals. The microscope has been adjusted before shipping,
Unprofessional-person should not disassemble and remove any other parts. If you have any
questions, please contact with manufacturer or local distributor.
9. Wide voltage input 100～240V, 47-63Hz, if not in this range, it may cause damage for equipment.

10.Don’t open microscope base plate when in use or else exposed electrical element will lead to
electric shock. Before replacing the lamp or fuse, please turn off power switch and pull out the
plug from the socket.
11.Do not use alcohol, gasoline, paper and other combustibles near the instrument, to prevent a
fire!
MARK
MEANING
Surface will be hot, don’t touch it.
Please read instruction manual carefully at first. Misuse will lead to user hurt or
instrument damage.
It is near the fuse socket, means be care of electric leakage.
Main switch “ON ”
Main switch “OFF”
⚫PREPARATION
1. Microscope is precise instrument, carefully operation, avoid collisions and shaky.
2. Using environment should not be in direct sunlight, high temperature or high humidity and dusty, avoid
violent shaky.
3. Tension for coarse focusing knob

4. Please leave enough space(10cm)
for ventilation.
5. Please follow Figure-2 to carry
microscope
★Firstly, take away sample, filters
and round stage parts avoid damage .
★If the microscope is leaning slightly,
not in good position, rubber gasket
may be fall off.
Figure-2 Carrying
⚫MAINTANCE AND STORE
1. Please use gauze with 70% ether and 30% alcohol mixed liquor to gently wipe the
lens, Alcohol and ether are inflammable material, please take them away from fire.
