E2PROM Replacement
Data accessed in the Convergence Adjustment Mode is stored in IC8D01on the PCB-SIGNAL and on the PCB-
E2P. Replacement PCB's are supplied pre-aligned by model size so that only fine adjustments should be
necessary after replacement. Other service data is stored on the PCB-E2P located on the DM assembly.
When replacing the DM assembly, retaining the original PCB-E2P will eliminate the need for any realignment.
The following tables are provided as a guide in case of total data loss.
