There are only two state of upper deck ends fixing:
1. Fully fixed end. Two outer screw or pivot balls without ST09 must be used.
Two additional inner screws (pivot balls) only (without outer screws/balls)
are not enough for secure fixing.
This state is indicated by two outer red dots in setup sheet.
2. Floating end. One central screw must be used. All outer screws or pivot
balls must be removed or used only in conjunction with ST09.
This state is indicated by one central red dot in setup sheet.
There is not any third (and fourth) state of upper deck end fixing for flex setting so we don't need additional markup decoration.
To me that is not very clear.
On the setupsheets the topdeck has three holes on front and rear. In the manual it has five holes. How does that add up?
Floating end I understand. No prob.
Fully fixed end?
If there are five holes back and front, then there are more possibilities.
For instance the front end. Option one: two screws on the outside. Option two: two screws on the inside left and right from the middle hole. Option three: two screws on the outside and two screws on the inside is total four screws. That would be three options.
Even more options if the middle screw was to be used.
Please elaborate and explain.
