I. Safety Notes
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. When moving the instrument, please use two hands to grip with the two sides of the microscope
body.
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 replacing the halogen lamp or the
fuse, then cut off the power, and do the operation after the lamp bulb and the lamp house
completely cool down. (Specified: Halogen Lamp6V/20W)
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.
II. 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 possibly as you can.
3. The nosepiece and coarse/fine focus unit have a compact and precise frame; please don’t
disassemble them as possibly as you can.
4. Keep the instrument clean, wipe dust regularly, and be attention to avoid contaminating the
optical elements especially.
5. 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 aether. (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.)
6. 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

NOTE:
Operation Conditions:
1．Temperature: 0℃ ～ 40℃,Maximum
Relative Humidity: 85%.
2．High Temperature: High Temperature
and humidity 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

2.2.3 Installing objectives (Fig.5& 6)
1. Adjusting the coarse focus knob until the
support device of the mechanical stage
reaches its low limit position.
2. Screw the lowest magnification objective
into the nosepiece from the left or the right
side, then revolve the nosepiece clockwise
and mount other objectives by the sequence
of low to high magnification
Installing objective this way will make the
change of magnification to be easier during
using.
Clean the objective regularly, for lens is
susceptible to dust.
When operating, use 10×magnification
objective to search and focus specimen
firstly, then replace with higher
magnification objective if necessary.
When replacing the objective, slowly turn
the nosepiece until you hear “clicked”,
which means the objective is in the
required position--the light path center.
2.2.4 Installing the color filters (Fig.7)
1. Turn the condenser bracket①out at the
direction of arrow in Fig.7
2．Put the required filters②into the holder on
the bracket, and then turn the bracket back to
