WHEN AND HOW TO COPY EEPROM
DATA FROM L BOARD TO DG BOARD
The table below shows when it is necessary to copy the "Color
Wheel Index Delay" and "White Balance" adjustment data
stored in the EEPROM IC on the DMD Drive C.B.A. (Circuit
Board L) to the EEPROM IC on the Main C.B.A. (Circuit Board
DG). After replacing the corresponding parts, copying must be
done using "EEP COPY L->DG" in Factory Adjust Mode at the
user's location.
When replacing the following parts, copying is necessary.
Replacement

or
Substitution

set
Note:
1. When re-installing the original parts, copying is not necessary.
2. The "Color Wheel Index Delay" and "White Balance" data stored in EEPROM
IC on the DMD Drive C.B.A. (Circuit Board L) is adjusted at the factory.
(For reference)
When replacing the following parts, copying is not necessary.
