A scanning objective is the first objective of a microscope. You always start on the scanning objective and it has the lowest magnification and is red.
To pinpoint the location on a slide you wish to magnify further. It's low power and provides an overview of the area before you switch to higher power.

The objective lens that focuses closest to the slide is 100x, it has the longest lens so the highest power. Be careful not to crack the slide and make sure you use oil if it is an oil immersion lens.

The scanning power objective relates to the objective lens. Most microscopes provide two or more objective lenses to give a choice of magnification power. Some also include an oil immersion lens for even greater magnification.

Try it any other way and you'll see. The scanning objective has the largest field of view, the greatest depth of field, and the greatest working distance. It is the most forgiving objective. It is the easiest to find the specimen and focus on it.
