The telescopic sections can only be telescoped individually, one after the
other.
When Extending you must always extend the telescopic section with the
highest numbering first, then the telescopic section with the next lower
numbering, etc. (e.g.
IV, III, II, I).
The telescopic sections are always retracted in the reverse order of
extending.
