Replacement
1 Position the device on the work surface with the rear side facing you.
2 Use the guides inside the handle to insert the RFU-and-USB Assembly into the new Handle. See
Figure 39.
3 Make sure that both the mount and PCA are fully seated and flush with the Handle’s bottom.
4 Wrap the RFU-and-USB cable around the plastic standoffs and guide through the cut-out.
Slightly wiggle the ferrite core to make sure it fully fits into the handle. See Figure 40.
5 Align the Handle against the Front Case.
Make sure not to pinch wires between the Handle and the Front Case.
