The Tulip-Dome consists of two "leaves" and it is important
that the largest "leaf" is the outermost "leaf" (4).
This can easily be done by pushing the "leaves" away from
the sound tube with your forefinger and middle finger (5).
This will make the large "leaf" bend forward. Then you
push it back and it will be placed on top of the smaller
"leaf" (6). Now the Tulip-Dome is ready for insertion (7).
