How to play lower C# on tenor recorder?

Well I will just give you the fingerings for tenor and soprano recorders.T(thumb hole) and 1,2,3,4,and 5 being the single top hole 1 being the one closest to the mouthpiece and 6 being the first bigger double hole 7 being the samller and 8 being the last bigger double hole and 9 being the smaller hole.C means cover, O means open,/ means pinch or cover any half of the hole,and - means cover the bell or the end piece of the recorder like your knee if sitting.Going from lowest to highest, starting on the first C(treble clef) the is below the staff and that has a ledger line.
Enjoy!
