COMPONENT NUMBERING SYSTEM

Serviceability of this chassis is enhanced by road mapping on the top and bottom of the circuit boards. In addition components are marked as to the Component Type and generally marked as to their circuit. The operation and features of the “ITC” chassis is similar to the “CTC” series chassis. However the component numbering system is different than that in the past in the “CTC” series chassis but is similar to the component markings of the “TX” series chassis. The component numbering for the chassis reflects the component’s type and use as to the general circuit areas it is used. The component labeling system is described below:

COMPONENT DESIGNATION: X X XXX
