Safety Precautions

1. Be careful when opening box, prevent lens glass to stick to fingerprint, perspiration other

factors influence observation, prevent lens and other attachment drop damaged.

2. Avoid placing the microscope in place with direct sunlight, high temperature or high

humidity, dust, and strong vibration. Ensure that the stage is flat, horizontal and strong

enough.

3. If a bacterial solution or water spatters spill on the stage, objective or observing tube,

immediately unplug the power cord. Then, wipe off any solution or water with to keep the

microscope dry. Otherwise, it could damage the instrument.

4. To avoid blocking the natural convection air for cooling, make sure the left, right, top, and

rear of the microscope are at least 10 centimeters away from the wall and other objects.

5. Grounding the machine to avoid lightning strike.

6. To ensure safety, always make sure the main switch is in "O" (disconnecting) and cut off

the power while waiting for the LED lights and the lamp room to cool completely. Input

voltage check: the input voltage indicated on the back of the microscope is consistent with

the supply voltage, otherwise the microscope will be seriously damaged.

7. Use our company dedicated wire.

8. When carrying this product, one hand should firmly hold it by gripping the recess in the

front lower part of the main body and the other holds the recess in the rear of the main

body.

★Do not hold any other parts (such as the upper part of the illumination pillar, focus knobs, eyepiece tube,

or stage) when carrying the microscope. Doing so might result in dropping or failure of this microscope.

Care and Maintenance

1. All lenses have been calibrated, please do not disassemble by yourself.

2. The structure of objective converter and coarse and fine focus mechanism are precise,

please do not disassemble easily.

3. The instrument should be kept clean, have to regular removal of dust, special attention

should be paid to do not contaminate the optical parts when cleaning.

4. The stain of the lens, such as fingerprints and grease can be wiped with a small amount of

ethyl ether (70%) and alcohol (30%) mixed solution.

5. Do not use organic solvents to clean the non-optical parts of the microscope. Please use

neutral detergents when cleaning.

6. When using, if the microscope be wet liquid, should immediately cut off the power and

dry.

7. Do not disassemble any part of the microscope, which will affect the function or reduce

the performance of the microscope.

8. The instrument should be placed indoor with cool and dry, covered the dust cover when

not in use. Cover up, must wait for the lamp room to cool down.

9. The microscope usage environmental requirements:

a) For indoor use;

b) The environment temperature range: 10 ℃~ 35 ℃;

c) Maximum relative humidity: 80% at 31 ℃, linear temperature down to 34 ℃is 70%,

60% at 37 ℃, 50% at 40 ℃.

10. Microscope to store and transport environment requirements:

a) the environment temperature range: - 40 ℃~ + 70 ℃

b) relative humidity range: 10% ~ 100%

c) atmospheric pressure range: 500 hpa ~ 1060 hpa

Because the solvent such as ether and alcohol are extremely flammable, do not operate

power switch of various electrical equipment when using, and keep away from open fire, please

ensure indoor ventilation.
