vFollow the suggested actions in the order in which they are listed in the Action column until the problem is solved.

vSee Chapter 7, “Parts listing, RS210 Types 6531, 6532, 6533, and 6534,” on page 177 to determine which components are customer replaceable units (CRU) and which components are field replaceable units (FRU).

vIf an action step is preceded by “(Trained service technician only),” that step must be performed only by a Trained service technician.
