To focus a slide from low power of magnification to high power one needs to change the objective lens. A high power objective lens is brought more nearer to the object for getting proper resolution.
After having a slide on the microscope, slowly turn large knob until you can see what is on the slide, then turn small knob to view better details on the slide like silhouette or cilia. Turning the dial on front to control light can let a person see what's on the slide better. Some microscopes have multiple lenses, so start with 4x and after focusing, go to 10x refocus, than 40x and refocus.
The user would have to adjust the diaphragm to let in more or less light for their needs.
you should turn the fine adjustment knob NOT the course adjustment knob. Turn the fine adjustment knob until you can see the specimen under the microscope well.
Just answered the following question above. ^

Lower the stage so the objective does not crush the slide.
describe the procedure of slide setup
The high power objective in a microscope is the largest lens in the microscope.

Using high power objective lense
High Power Objective
After switching the microscope from low to high power, you may need to readjust the diaphragm to regulate the amount of light entering the lens. This adjustment helps maintain optimal image brightness and clarity at different magnifications. Start by opening the diaphragm fully and then gradually close it until the image is clear and properly illuminated at high power.
Centering the specimen before switching to high power on a microscope helps ensure that the area you want to observe is in focus and at the center of the field of view. This is important because high power magnification has a narrower field of view and lower depth of field, making it more challenging to locate and focus on the specimen if it is not first centered.
When working with a microscope you should always take procauctions but one question I am asked a lot is When working with a microscope do you open or close the diaphram when working with the medium- and high-power objective nobs? The answer is you keep it open if you don't you won't be abler to see any thing.

Coarse Adjustment
The high-power objective on a microscope is larger lens with higher magnifying power. (40x)
The coarse adjustment knob on a microscope should never be used with the high-power objective lens. This can cause damage to both the lens and the slide being viewed. Instead, it is best used with the low-power or scanning objective lens for initial focusing.
Do not allow the high power objective to tough the lenses

A smaller area, but larger objects is in view with a microscope on high power.
