1. Safety note
1. Carefully open the box, avoid the accessories, like lens, dropping to ground and being
damaged.
2. Do keep the instrument out of direct sunlight, high temperature or humidity, dusty and easy
shaking environment. Make sure the stage is smooth, horizontal and firm enough.
3. If the bacterium solution or the water splash to the stage, objective or viewing tube, pull
out the power cord at once, and wipe up the microscope. Otherwise, the instrument will be
damaged.
4. When running, the lamp house and nearby parts will be very hot. Please ensure there is
enough cooling room for them.
5. Make sure the instrument is earthed, to avoid lighting strike.
6. For safety, be sure the main switch is in “O” (off) state before replace the lamp or the fuse,
then cut off the power, and do the operation after the lamp bulb and the lamp house
completely cool.
7. Check the input voltage: be sure the input voltage which signed in the back of the
microscope is consistent with the power supply voltage, or it will bring a serious damage
to the instrument.
8. Use the factory supplied power cord, please.
2. Maintenance
1. All the lenses have been well checked and adjusted. It is forbidden to disassemble them
yourself.
2. The nosepiece and coarse/fine focus unit have a compact and precise frame, please don’t
disassemble them as possible as you can.
3. Keep the instrument clean, wipe dust regularly, and be attention to avoid contaminating
the optical elements especially.
4. The contaminations on the prism, as finger mark and oil, could be gently wiped with a piece
of soft cloth or tissue paper, gauze which has been immersed in pure alcohol or xylene. ( note
that the alcohol and the xylene are all burned easily, do not let them near the fire, and use
them in a drafty room as possible as you can.)
5. Don’t use organic solvent to wipe the non-optical elements, when you need to clean, use

3
the soft detergent, please.
6. When using, if the microscope is splash by liquid, cut off the power at once, and wipe up
the moisture.
7. Do not disassemble any parts of the microscope. That will affect the function or decline
the performance of the microscope.
8. Place the instrument in a cool, dry position. After using the microscope, remember to
cover it with dust helmet. Do wait for the lamp house cooling completely before cover.

When the image is sharp by observe
with both eyes, the image of pointer will on
the field of view simultaneity. If not, you can
turn the pointer rocker in four direction (up,
down, left, right) gently, make the pointer on
the field of view. If the image of pointer is
unclear, you can turn the pointer knob to
adjust the lightness until turn up a green
sharp image.

after focusing the eyepieces.
5-2-2Adjusting Pointer
It will be a clear green pointer image
after adjusting he Primary Minor, if the
pointer not clear or invisible, you can turn the
pointer knob moderately or turn the pointer
rocker in four direction (up, down, left, right)
gently to adjust lightness and height of the
pointer, which will see the clear pointer
image simultaneous on the field of view of

8.Trouble shooting
Some problems will happen in the using of the microscope, you could solve them according the
following list.
PROBLEMS
REASON FOR PROBLEM
SOLUTION
I、Optical Part:
1、Illumination is
opening, but the
field of view is
dark.
The poor contact exists in the lamp
house and the illumination system.
Ensure the contact pin and the lamp
holder pin work well
The lamp bulb spoils
change a new bulb
The brightness adjustment knob is set
too dark
Adjust the knob in a proper position
No use the appointed lamp bulb
use the specified halogen Lamp
6V30W
2、The edge of the
field of view has
shadow or the
brightness is
asymmetry
The nosepiece is not in the located
position
Adjust it into the located position
The surface of the lamp become
black
Change a new lamp bulb
The surface of the lens is moldy or
has contaminant
Clean the lens
3、Find dust and stain
in the field of view
There are stains on the specimen
Change the specimen
There are stains on the eyepiece
Clean the eyepiece
4、The image is
defocus\low-resolu
tion
The objective damage
Mend and correct the objective (send
to factory for overhauling)
The lens of the objective and
eyepiece is moldy or have
contaminant
Do cleaning
The opening of Aperture diaphragm
and field diaphragm is not proper,
and too much astigmatism.
Change the opening of the aperture
diaphragm and field diaphragm
Fine focus system is broken
Examine and repair the fine focus
system(send to factory for
overhauling)
The objective is not in the center of
the light path
Turn the nosepiece to the located
position

19
5、The image focus
surface incline (one
side is clear and the
other side is faint)
The illumination light incline serious
Adjust the filament position, let the
light distributing of the field of view
become symmetrical and bright
The specimen don’t correctly place
Put the specimen on the right position
The nosepiece is not in the located
position
Turn the nosepiece in the required
position
6、The eyes are
uncomfortable, the
left and right fields
of view is not
coincided .
The interpupillary distance is not
correct
Adjust the interpupillary distance
correctly
The diopter is not right
Adjust the diopter according your
sight
Can’t adapt to binocular observation
When look into the objective, do not
stare at the specimen but at the whole
field of view, or move the eyes away
to see other things, then back into the
objective
7﹑The pointer is
unclear or invisible in
the field of view
The lightness of pointer is not enough
or the pointer is not in the middle of
the field of view
Turn the pointer knob to adjust the
lightness or turn the rocker in four
direction(up, down, left, right)softly
which make the pointer in the middle
of the field of view
