Fitting suppression ferrites
In certain installation scenarios interference may be experienced in the form of data corruption when reading and
writing to external storage via the card reader. Under these circumstances the supplied suppression ferrites should
be fitted to the card reader’s cable, as described below.
Two of the suppression ferrites should be fitted at 6 mm (0.24 in) intervals from the connector end of the cable and
the third ferrite at a distance of 53 mm (2.09 in) from the rear of the card reader. Cable ties are also supplied to
help secure each ferrite in place.
