To set up the microscope for your first observation, follow these steps:
1. Position the microscope on a stable, solid surface near an electricity supply.
2. Make sure the light switch is set to 'off' before use.
3. The microscope has two light sources: transmitted light (from below) and reflected light (from above). Set the switch to 'II' for reflected light, 'I' for transmitted light, or 'III' for both.
4. The color filter disc under the microscope table can be used to aid in viewing very bright and transparent objects. Select the appropriate color for the specimen.
5. Loosen the xxxx on the microscope head and rotate it into a convenient position.
6. Place the microscope's table with the focus xxxx in the lowest position and rotate the objective revolver until it locks on the lowest magnification (4X).
7. Insert the 10X eyepiece into the Barlow lens and ensure it is fully inserted into the microscope head.
8. Slide a specimen onto the microscope table directly over the lighting.
9. Look through the eyepiece and carefully turn the focus wheel until you see a sharp picture.
10. To increase the magnification, slowly pull the Barlow lens out of the monocular barrel. For even higher magnification, you can use the 16X eyepiece and rotate the objective revolver to a higher magnification (10X or 40X).
11. When changing the magnification, readjust the focus wheel to sharpen the image.
Note: Always start with the lowest magnification and adjust the focus wheel accordingly. Be careful not to move the mechanical plate too fast to avoid damaging the objective lens and slide.
