Figure 7: Typical Label
• “W-_ _ _ _” represents a wire or cable.
Cables may also carry the assembly
numbering format in certain circumstances.
This is especially true of ribbon cables.
Most circuit boards and components within this
display carry a label that lists the part number of the
unit. If a circuit board or assembly is not listed in the
Replacement Parts List in Section 4, use the label to order a replacement. A typical
label is shown in
Figure 7 . The part number is in bold.
