USER NOTICE
1. Safety Precaution
1. Carefully open the box, avoid the accessories, like lens, dropping to ground and being
damaged.
2. Check the input voltage, be sure the input voltage which signed on the microscope is
consistent with the power supply voltage, or it will bring a serious damage to the instrument.
3. 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.
4. To prevent the microscope body from turning over, its pivot angle must be limited to 30°.
5. .A microscope is a precision instrument. Handle it with care and avoid subjecting it to sudden
or severe impact.
6. Make sure the instrument is earthed, to avoid lighting strike.
7. Do not disassemble any part of the microscope, especially the electrical parts on the bottom
side as this may result in electric shock.
8. Use the factory supplied power cord, please.
2. Maintenance and Storage
1. All the lenses have been well checked and adjusted. It is forbidden to disassemble them
yourself.
2. The binocular viewing head and focusing unit have a compact and precise frame; please
don’t disassemble them as possibly 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 fingerprint and oil, could be gently wiped with a piece
of soft cloth or tissue paper, gauze which has been immersed in pure alcohol or ether.
(Note that the alcohol and ether are highly flammable, do keep them away from the
fire or potential sources of electrical sparks, and use them in a drafty room as possible
as you can.)
5. Do not attempt to use organic solvents to clean the microscope components other than the
glass components. To clean them, use a lint-free, soft cloth slightly moistened with a
diluted neutral detergent.
3
6. If the microscope is splashed by liquid during using, cut off the power at once, and wipe up
the moisture.
7. Do not disassemble any parts of the microscope, which will affect the function or decline
the performance of the microscope.
8. Place the instrument in a cool, dry position. When not using the microscope, keep it
covered with a dust cover.

2.2 Detailed Assembly Procedure
2.2.1 Mounting binocular viewing head
(Fig.1 Fig.2)
1. Rotate the objective① into the objective mount
thread on the lower end of the zoom body. ② , as ③
in fig.2.
2. Aligning the positioning pin of the zoom body③ to
the positioning groove on the binocular viewing head
④, insert the dovetail mount at the bottom of the
viewing head into the mounting port on the zoom body
③, and tighten the viewing head clamping screw⑤
with provided hexagonal driver.
Note:
Working Environment Requirement：
1．Ambient temperature: 5°C to 40°C
. (41°F to 104°F)，Maximum R.H：85%。
2．High Temperature will result in a mildewing,
dew and even ruinous instrument.
3．Avoid placing the instrument in a dusty
environment. When ending your microscope
operation, please cover it with the dust cover.
4．Lay the microscope in a plan and stable
position, please.

2.2.2 Mounting binocular head (Fig.3)
Loose the clamping bolt⑦ on the pillar⑥
and insert the binocular head and zoom body
assembly⑧into the bracket of the pillar, then
screw down the bolt⑦.
2.2.3 Mounting eyepieces (Fig.3 Fig.4
Fig.5)
1. Remove the eyepiece dust caps⑨ and gently
insert two adjustable eyepieces ⑩ into the
eyepiece sleeves until they stops, as in Fig.4.
2. Using the Eye Shades
When Wearing Eyeglasses:
Use with eye shades in their normal
folded-down position. This will prevent
eyeglasses from being scratched by the eyepiece
as in Fig 5.
When Not Wearing Eyeglasses:
Extend the folded eyeshades. This makes
observation easier by preventing the inverse
incidence of light from between the eyepiece and
your eyes.
2.2.4Connecting the power cord (Fig.6)
1. Turn the main switch① on “O” (off) state
before connecting the power cord.
2. Insert the power plug② into the power jack
of the microscope; make sure the connection
is well.
3. Plug the power cord ③ into the power
supply receptacle safely. Make sure the
connection is well.
2.2.5 Mounting glass stage plate (Fig.7)
If necessary, the original plastic stage
plate can be replaced by a glass one.
● Both top and bottom illuminators are LEDS.
● Permitted power supply voltage：
100V～240V。

2.2.6 Mounting aperture iris
diaphragm attachment
(Fig.8 Fig.9)
○Aperture iris diaphragm attachment
is optional.
1. Use the provided hexagonal driver
to loose the clamping bolt and
remove the binocular viewing head
①.
2. Mounting the aperture iris
diaphragm attachment② to the top
end of the zoom body.
3. Mounting the binocular head into
the aperture iris diaphragm
attachment and tighten the clamping
bolt③.
Adjusting aperture iris diaphragm
● The aperture iris diaphragm adjustment can increase the image contrast and focus depth.
● The size of aperture iris diaphragm can be adjusted. Switch the lever to left to open the aperture
iris diaphragm; to the right, to close the aperture iris diaphragm. Check the effect
during
observation.
★ Do not close the aperture iris diaphragm too much, or it will decrease the resolution and lead
to
lack of illumination.
★ Closing the aperture iris diaphragm to the minimum state will result in faintness in field of view.
In this case, adjust the aperture iris diaphragm to the half open state.
★ Closing the aperture iris diaphragm to the minimum state and increase the magnification of the
zoom body will result in lack of illumination around circumference of field of view.

3. Adjustment and Operation
3.1 Adjusting binocular viewing head
3.1.1Adjusting interpupillary distance (Fig.10)
Different users have different interpupillary distances.
So when users change, do the interpupillary distance
adjustment.
While looking through the eyepieces, hold the left and
right of the binocular assembly①and adjust the eyepieces
by opening or closing them for binocular vision until the
left and right fields of view coincide completely.
3.1.2 Adjusting diopter ring (Fig.11 Fig.12)
1． Set the dioptor rings of both eyepieces to “0”position.
(Do this when users change, because different users
have different diopters.)
2．Place an easy-to-observe specimen on the stage plate.
3 ． Rotate the zoom body knob ③ to the highest
magnification 5×(or 6.4× ,or 10×), and turn the
focusing knob④ to focus the specimen.
4 ． Rotate the zoom body knob ③ to the lowest
magnification 0.8 × , looking only into the left
eyepiece, adjust the diopter ring on left eyepiece to
focus the specimen. Then do the same thing for the
right one.
5．Repeat item 3 and 4 until the specimen image can
always focus without any adverse effect of the
changes of magnification on the definition of the
image.
Fig.12 shows the focusing part of Stereo
Microscope .There are coarse focusing knob⑥ and
fine focusing knob⑦ in this kind of microscope.
● The working distance of the objectives listed in
standard outfit is all 78mm for these three kinds of
stereo microscopes.
When 2× objective is chosen , it is necessary to
mount the binocular head bracket ⑤onto the lower
position. Remove the clamping bolt with provided
hexagonal driver and move the bracket down to the
lower position and set it with original bolt (Fig.11).

3. 2 Focus adjustment
3.2.1 Adjusting the rotation tension of the focus
adjustment knob (fig.13 fig.14)
For these Microscopes ,the tension has been
adjusted well before delivery.
1．Rotate the focus adjustment knob① to move
the slider② to a lower place for fear that the
zoom body drops down suddenly if the
tension is decreased too much.
2． Hold the focus adjustment knobs① with both
hands, stop the left knob and rotate the right
knob to increase or decrease the focus knob
tension.
3. Brightness adjustment: the right brightness
adjustment knob ③ is used to adjust the
bottom illumination, and the left brightness
adjustment knob④ is used to adjust the top
illumination
3.2.2 Adjusting tension collar（Fig.15）
1. If the microscope body falls down by its own
weight or the focus obtained by fine
focusing is lost immediately, the rotation
tension adjustment may be too light. In this
case, rotate the tension collar with provided
spanner to increase the rotation tension..
2. The brightness adjustment method is the same
as that of fig14。
