E2PROM Replacement
Data accessed in the Convergence Adjustment Mode is stored in IC8D01on the PCB-SIGNAL. Replacement
PCB's are supplied pre-aligned so that only fine adjustments should be necessary after replacement. All 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.
