OverviewInstructions:
1. Put in the battery, turn on the power switch, the light will turn on
2. Turn the focus knob counterclockwise and lift the lens up to adjust the light brightness.
3. Take the specimen first and place it on a glass slide. You can use another glass slide to cover it as a cover glass. Because this is a children's toy model and not a professional research, we have omitted some steps and then put it on. The slide with the specimen on it is placed on the stage and circled on the clip. The specimen is moved to the middle of the light-transmitting hole. The objective lens needs to be adjusted when placing the slide.
4. Rotate the objective lens, look at the lens, and adjust the focus upwards little by little with your right hand. When you can see something, adjust it very finely until you can clearly see the details of the object being observed. Beginners may need to repeat this process several times until they can see clearly. It is impossible to adjust to the appropriate position in one go.
