When preparing the microscope to be covered up at the end of lab/class/day,
1) the body tube has to be turned around to fit inside the protective cover,
2) the mechanical stage is centered so it won't damage the protective cover,
3) the stage is placed in its lowest position,
4) the stage is clean meaning that the slide has been removed and there isn't any water or debris on the stage,
5) the scanning objective (lowest magnification objective) is in place, and
6) the light source is switched off.
