This set relates the main block (flash memory) and the HDD (hard
disk drive) with a unique ID to protect the copyright.
If the MAIN board or flash memory (IC1030 on MAIN board)
and HDD were replaced, the relationship between flash memory
and HDD is lost, thus causing the HDD to fail. Therefore, the ID
relational work is required.
Perform the work by proper methods, since the work required var-
ies as follows depending on the parts to be replaced.

1) When the MAIN board or flash memory (IC1030 on the

MAIN board) and HDD were replaced at the same time

2) When the only MAIN board or flash memory (IC1030

on the MAIN board) was replaced

3) When the only HDD was replaced

The CD-R for service used when installing the data to the
hard disk must have same version as that of the set. Before
starting the work, be sure to check the version of the set and
the CD-R for service. (See “Making CD-R for service” on
page 21 and “Check the versions” on page 22)

Executing this operation without replacing the hard disk drive

causes the user data to be erased. Accordingly, do not execute
this operation by mistake.

When the MAIN board or flash memory (IC1030 on the MAIN
board) and HDD were replaced at the same time, the processing
such as system ID setting and formatting are required. After the
MAIN board or flash memory (IC1030 on the MAIN board) and
HDD replacement, be sure to execute all of the following steps.
