SECTION 3 (cont.)
2 Remove the protective tab
from the NovoFine dis-
posable needle.
3 Screw the NovoFine dis-
posable needle firmly onto
the PenFill 3 mL cartridge
until it is tight.
Never place a NovoFine disposable needle on your
NovoPen 3 until you are ready to do an air shot and give an
injection.
If the NovoFine needle is "left on, " some liquid may leak out
of the PenFill cartridge. This may cause a change in the
strength of Novolin 70/30 or Novolin N insulin.
