Operator's DVD is an interactive computer software configurable for different solutions regarding crane-range, mode of operation as well as different stabilizer solutions.
This DVD consists of two main components, "General operator's video" and "Specific operator instruction".
The "General operator's video" is more like a movie, where there's no need for the viewer to interact.
In the "Specific operator instruction" section, the viewer can choose from lots of different chapters containing e.g. instructions on how to operate the crane, safety precautions, service instructions, etc.
