(a)
Turn the first officer's control wheel clockwise 80 degrees and hold.
(b)
Turn the captain's control wheel counterclockwise until you get the transfer mechanism stops to touch. 1) Make sure the control wheel turns more than 138 degrees. 2) Make sure the transfer mechanism can move freely when you
