For the main carrier two service positions are possible (3.1).
A: For faultfinding on the component side of the main carrier.
B: For (de) soldering activities on the copper side of the main carrier.
Position A can be reached by first removing the mains cord from it's fixation, then loosen the carrier lips (1) and then pulling the
carrier panel (2) for approximately 10cm.
Position B can be reached from position A after disconnecting the degaussing cable. Put the carrier on the line transformer side.
