Product Usage Instructions

Storage and Handling

Store the microscope in a dry and clean environment, away from direct sunlight, high temperatures, and violent vibration.
Handle the microscope with care to avoid impact and abrupt movement during transportation.

Cleaning and Maintenance

Keep all lenses clean by blowing off fine dust with a hand blower or wiping gently with a soft lens tissue.
Clean fingerprints and oil marks on the lens surfaces with a tissue moistened with a 3:7 mixture of alcohol and ether.
Avoid using organic solutions to clean other surfaces, especially plastic surfaces. If necessary, use a neutral detergent.
Do not disassemble the microscope after assembly to prevent damage.
After use, cover the microscope with the provided dust-cover and store it in a dry, clean environment to prevent rust.
Periodically check and clean the microscope to ensure proper performance.

Setting up the Microscope

Place the microscope base on a flat, firm surface and position the frosted stage plate on the base.

Focusing and Observation

Check the coarse focus knob on either side of the main support to ensure it turns easily.
To adjust the degree of tightness of the focusing arm, hold one focusing knob and turn the other to attain a suitable position. Clockwise direction is tight, counterclockwise is loose.
Set the specimen in the center of the stage plate and clamp it if necessary.
Plug the small round plug into the back of the microscope base and connect the opposite end to a power outlet.
Turn the focusing knob and observe the specimen through the right eyepiece until the image is clear.
Observe the specimen through the left eyepiece and adjust the diopter ring until the image is clear.

Adjusting Eyepieces and Light Intensity

Adjust the two eyepieces along the direction indicated until they feel comfortable and a single image is seen.
Use the left rheostat (dimmer knob) to adjust the light intensity of the bottom (transmitted) light.
Use the right rheostat (dimmer knob) to adjust the light intensity of the upper (incidental) light.

Before use

Notice

The microscope should be stored in a dry and clean environment. Do not expose the microscope to the direct sunlight. Avoid high temperatures and violent vibrations.
This microscope is a precision instrument. Handle with care. Avoid impact and abrupt movement during transportation.
To keep the image clear, clean any fingerprints or stains on the surfaces of the lens.
Never turn the left and right focusing knob in the opposite direction at the same time. Microscope damage will occur.

Maintenance

All lenses must be kept clean. Fine dust on the surface of the lens should be blown off with a hand blower or wiped off gently with soft lens tissue. Fingerprints and oil marks should be cleaned with a tissue moistened with a small amount of a 3:7 mixture of alcohol and ether.
Never use organic solutions to clean the other surfaces (especially the plastic surfaces). If necessary, please use a neutral detergent.
Once assembled, do not take the microscope apart as this may cause damage to the microscope.
After use, cover the microscope with the provided dust cover and store it in a dry, clean environment to prevent rust.
To ensure proper performance, please check and clean the microscope periodically.

Operation

Position the glass stage
Place the microscope base on a flat, firm surface and position the frosted stage plate on the base. (Figure 1)
Adjust the degree of tightness of the focusing arm
Check the coarse focus knob on either side of the main support. The coarse focus knob should turn easily.
If you want to adjust the degree of tightness of the focusing arm, you can hold one of the focusing knobs and turn another one to attain a suitable position. The degree of tightness relies on the direction to be turned. The clockwise direction is tight; counterclockwise is loose. (Figure 2)
Set the specimen slide
Set the specimen in the center of the stage plate. If necessary, clamp the slide with the clips.
To operate, plug the small round plug into the back of the base of the microscope and then plug the opposite end into the power outlet.
Adjust focusing knobs and diopter
Turn the focusing knob and observe the specimen through the right eyepiece until the image of the specimen is clear.
Observe the specimen through the left eyepiece and adjust the diopter ring 1 until the image is clear. (Figure 3)
Adjust the interpupillary distance
Adjust the two eyepieces along the direction of the arrow shown in Figure 4 until the eyepiece feels comfortable and a single image is seen.
Use the left rheostat (dimmer knob) to adjust the light intensity of the bottom (transmitted) light.
Use the right rheostat (dimmer knob) to adjust the light intensity of upper (incidental) light.
