CAUTION
PARTS INTEGRITY
Tampering or unauthorized substitution of components may adversely affect safety of this product. Use only factory documented components for repair.
In most situations involving a malfunction of a circuit board, it is more practical to replace the board than to attempt isolation and replacement of the individual component. The cost of test and replacement will exceed the cost of a rebuilt assembly. As standard policy, rebuilt boards are available on an exchange basis.
Because of the exchange policy covering circuit boards, the following list does not include individual, circuit board mounted components. If circumstances necessitate
replacement of an individual component, which can be identified by inspection or from the schematic diagrams, obtain the replacement component from a local source of supply.
