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 bottom slot front of the frame, and

the other hand hold the rear end of the cross beam.

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 by

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.
