Motorola R2600 Service | Manual

A factory service manual (often bearing Motorola part numbers like 6880309E55 or similar, depending on the revision) is vastly different from an operator's manual. While the operator's manual tells you how to take a measurement , the service manual tells you how to fix the machine when the measurement is wrong .

The R2600 has built-in self-test (BIST) routines. When the unit boots, it runs a series of diagnostics. If it displays an error code (e.g., a phase-locked loop un-lock error), the service manual provides a diagnostic flowchart. These flowcharts guide you to measure specific test points (TP) on the circuit boards using a digital multimeter or an external oscilloscope. Schematic Diagrams and Board Layouts
