More about Step 4 - Verify Test Set Functioning
See "Locating the Out-Of-Lock (OOL) Indicators" on page 89
Out-of-lock (OOL) LEDs light when a phase-locked loop inside an assembly is failing.
The Signal Generator Synthesizer (A24), Receiver Synthesizer (A28), CDMA Reference
(A29), and LO/IF Demod (A31) assemblies have these LEDs mounted close to the top of
the modules. The location of each LED is labeled on the assembly.
