Replacing the C-PLUG 
Removing the C-PLUG 
It is only necessary to remove the C-PLUG if there is a problem on the basic de-
vice. After removing the labeling strip, the upper part of the C-PLUG can be care-
fully levered out of the slot on the Switch CPU using a slotted screwdriver until it 
can be gripped with your fingers and carefully removed. 
 
Notice 
The C-PLUG must only be removed or inserted when the power supply to the de-
vice is turned off. 
Inserting the C-PLUG in the Slot 
The C-PLUG is on the Switch CPU below the labeling strip. After removing the la-
beling strip, the C-PLUG is inserted in the receptacle with the socket connector 
leading. The notch in the casing must be on the right. The C-PLUG is inserted by 
pressing it into the receptacle until the C-PLUG is flush with the front surface of the 
CPU.
