Ⅰ.Safety Symbols
Ⅱ.Safety Notes
1. Open the box carefully to avoid the accessories, like lens, being polluted by fingerprint or
sweat strain, 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. When moving the microscope, one hand hook into the upper slot behind the frame, and the
other hand hold the front bottom of frame.
4. 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.
5. Be sure to keep at least 10cm away from the left, right, top, rear of the microscope from walls
and other objects, so as not to plug natural convection air, which is used for cooling.
6. Make sure the instrument is earthed, to avoid lightning strike.
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.

Ⅲ.Maintenance
1. All the lenses have been well checked and adjusted. It is forbidden to disassemble them
yourself.
2. The nosepiece, coarse and fine focusing parts are so delicate that it is forbidden to
disassemble them carelessly by yourself.
3. Keep the instrument clean, wipe dust regularly, and be attention to avoid contaminating the
optical elements especially. The objective lenses should be cleaned every month by professional.
4. We can clean the contaminations such as fingerprints and oil smudges on the prism by using
the tissue paper and solution, which is mixed by ether(70%) and alcohol(30%).
Noting that 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. Don’t use organic solvent to wipe the non-optical elements, when you need to clean, use 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.
9. Operating environment requirements for microscope:
a) Indoor use;
b) Temperature 5 ℃ ~ 30 ℃, humidity 45% ~ 80%;
c) Atmospheric pressure 86kpa ~ 106kpa, altitude below 2000m;
d) Working voltage 100V ~ 240V, frequency 50 / 60Hz.
10. Requirements for microscope storage and transportation environment:
a) Ambient temperature range: - 40 ℃ ~ + 55 ℃;
b) Relative humidity range: 10% ~ 95%.

3.Adjustment and Operation
A12.1095
3-1 Turn on the power（Fig.1）
First turn the main switch ①on the back of the
microscope body to the "○" (off) state. Insert the
power cord plug ⑤safely into the socket ④of the
adapter to ensure good contact.
Insert the adapter plug ③safely into the power base
②of the microscope to ensure good contact.
Insert the power cord plug ⑥safely into the power
supply socket ⑦to ensure good contact.
After the power is turned on, turn the main switch ①
to the "-" (on) state.
3-2 Adjust the brightness and switch up and
down illumination（Fig.2）
Turning the brightness adjustment knob according
to the direction indicated by an arrow on the
figure 2, the brightness strengthen.On the contrary,
the brightness decreases
As shown in figure 2, when the switch lever is
push-in, the light on the top is opening, the symbol
is ；When the light switch button is
push-out, the light on the bottom is opening, the
symbol is .
3-3 Light socket（Fig.3）
As shown in Fig.3, there are red dots in the socket
and plug,. Before the plug is inserted into the socket,
the direction should be adjusted until their red dots
are aligned.
The symbols on the left and right sockets are
corresponding with the switch button of light
source.As shown in the figure, is the socket of
upper light source, which is corresponding with the
state of pushing in the knob of switching light source.
is the socket of lower light source, which is
corresponding with the state of pushing out the knob
of switching light source.
If the upper and lower light source switch button
is inconsistent with the state shown in the diagram.
Check the light source plug and make sure the plug is
plugged into the appropriate socket.

3-4 Placing the Specimen（Fig.4）
Pull out the movable claw, put the specimen
in the corresponding slot, loosen the movable
claw and clamp the specimen.
★Be careful when changing the objective. When
the objective needs to be replaced after observing
the specimen with a short working distance
objective, the objective may collide with the
specimen
3-5 Adjusting the interpupillary distance
（Fig.5）
The interpupillary distance range: 47mm～
78mm.While looking through the eyepieces,
adjust for binocular vision until the left and right
fields of view coincide completely.

3-7 Focusing（Fig.7）
1. When camera is not used
Push the light path selector rod (as shown in
Fig. 7) in completely and observe with binocular
eyes. Use 10 ×In order to prevent the specimen
from colliding with the objective, the electric
stage should be raised first to make the specimen
close to the objective, and then the focusing hand
wheel should be rotated slowly and reversely to
make the specimen descend, and at 10 ×Search
the image in the eyepiece, and then press the
speed control button to switch to the low rate
focusing gear for fine adjustment. At this time, the
lens can be converted to other magnification
objective to achieve focusing without damaging
the specimen.
2. When camera is needed
Push the light path switch selector rod (as shown
in Fig.7) to the end for binocular observation.
After the image is clear, pull it out again for
observation through the camera system.
The hand wheel buttons on both sides work
independently, and different focusing speeds
can be set respectively. The speed gear is
displayed on the touch LCD screen.
3.Focus upper limit
In actual use, if you want to limit and lock the
stage height, that is, the upper limit position of
focusing according to the situation, you can set
the temporary upper limit position on the touch
screen. Please refer to the touch screen manual for
detailed operation instructions.
