## Normal function

**Start** begins surveying data. The button’s title reflects the action it will start.

**Pause** lets you continue a path after moving around obstacles. For example, while surveying a drain, press Pause, move around the obstacle, then press Start. The system treats the drain at your new position as a continuation of the same drain.

**Stop** ends surveying the area. The next Start begins a separate area. For example, while surveying a drain, press Stop, move, then press Start. The system treats this as a new, separate drain.
