display. Below is the information on the EEPROM IC (ROM correction) under 3 possible situations:

1. In the case that the correction point existence data is other than 0 (ie. correction file exists), EEPROM checksum display for
the microprocessor shall be made after calculating checksum by summing up the content of data area from EEPROM IC.

2. In the case when no EEPROM IC is installed. It is display as below (no display of checksum data)

3. In cases that the filename is different even though a EEPROM is installed, or no correction file exists, [NG] shall be displayed
(the correction point existence data is set to 0 at this condition).

Note: Microprocessor firmware refers to version number for microprocessor IC located on PANEL P.C.B.. It is subject to change
which would be updated accordingly. ROM correction checksum refers to the HEX code that is displayed upon key buttons pressed
if an EEPROM is loaded in the unit.

Below is the process flow chart of ageing for the CD/DVD changer unit. (CRS1D)
