NOTE: Take special care when following the procedures listed below.
■ Two ferrite core noise filters come packed with the printer. One is for the
interface cable, while the other one is for the cash drawer drive cable.
■ The ferrite core is normally packed so
it is open, as shown in Fig 3-2. If you
find that a ferrite core is not open, use a
pointed object to pry the plastic lock of
the ferrite core apart (Fig 3-1). When
you do, take care not to damage the
ferrite core or the plastic lock.
