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

7. When using, if the microscope is splashed by liquid, cut off the power at once, and wipe up the

moisture.

8. Do not disassemble any parts of the microscope, which will affect the function or decline the

performance of the microscope.

9. Place the instrument in a cool, dry position. When not using the microscope, keep it covered

with a dust cover. Make sure the lamp socket is cool before covering the microscope.

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
