Removing the C-PLUG
It is only necessary to remove the C-PLUG if there is a problem on the basic device. After
removing the labeling strip, the upper part of the C-PLUG can be carefully levered out of the
CPU module using a slotted screwdriver until it can be gripped with your fingers and
completely removed.
