Detailed explanation-1: -On LOW POWER ONLY, use the coarse focus knob to get the object into focus. If you cannot see anything, move the slide slightly while viewing and focusing. If nothing appears, reduce the light and repeat step 4.

Detailed explanation-2: -COARSE ADJUSTMENT KNOB-A rapid control which allows for quick focusing by moving the objective lens or stage up and down. It is used for initial focusing.

Detailed explanation-3: -Since the coarse-adjustment knob is used to find the specimen, combining this with the high-power objective lens could cause you to move the stage too quickly and break the slide under the lens.

Detailed explanation-4: -The coarse adjustment knob should only be used in the scanning objective lens because it moves the stage up and down in bigger increments and brings it closer to the lens faster, bringing it into focus. The fine adjustment knob is used on the higher objectives and brings the image into sharper focus.
