Ferrite Core Installation - Star Micronics SP317/347F Installation Manual

NOTE: Take special care when following the procedures listed below.
I A ferrite core is necessary on the printer interface cable to prevent the
generation of noise. If a parallel interface cable is used, a ferrite core must be
installed on the cable. If a serial intserface cable is used, a ferrite core must be
installed on the cable for all areas, except the US and Hong Kong.
I 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.
