Troubleshooting

Functional Diagnostics (Step 2)

The Functional Diagnostics (of the SERVICE MENU, shown in Figure

3-11 on page 65) check whether or not major portions of the Test Set are

functioning. They may pinpoint faults in the circuitry to the faulty

assembly, or they may direct the use of any or all of the AF, RF, CDMA

diagnostics to more extensively test the circuitry.
