A) Turn the machine OFF and remove the gauge!
B) Turn the machine on and allow the "Select Program" screen to appear. What color

long. Allow RINSE to complete i.e. [Remaining Time] = 0:00, then see part C.
2) IF BLUE: See part C.
C) Return to Dialysis Program ("Select Program" → 'Dialysis' → 'CONFIRM').
D) From the Home screen, set [Dialysate Flow] to 800 ml/min
E) Allow five (5) minutes BEFORE continuing to part F.
