FAULT DIAGNOSE AND TREATMENT
This part introduce fault diagnose and treatment.
Note: Certain circuits have lethal high voltages that allow only professional technicians to
perform maintenance operations on the unit. Special care must be taken when
troubleshooting with power on.
See Table 7-1 for fault diagnosis and treatment of each component.
