1.5 Symbols in diagrams and illustrations
If not otherwise indicated, diagrams and illustrations of actions depict the starting position
of the respective component for the described step.
For easier understanding, the diagrams only depict the components that are directly rele-
vant to the immediate context.
Arrows denote the positions where you have to perform an action or observe something in
particular. The color of the arrows denotes the type of actions and the sequence in which
they are performed:

ried out, e. g.:
