To meet FCC EMI guidelines, the iScan Plus v2 power supply comes with a snap-on ferrite collar
similar to those supplied with laptop computers and other portable electronic devices. The ferrite
collar should be snapped on the end of the cable leading from the power supply to the iScan Plus
v2 as shown in the illustration. Looping the power supply cable twice through the ferrite and
placing the ferrite as near the end of the cable as possible will maximize its effectiveness.
