• The ID for each equipment is registered on the PU board, the SYS board and SU board. So, if their
replacement is required, be sure to replace only one board at a time. Do not replace the SYS board

1. First, replace one of the board to be replaced.
2. Turn the power ON and confirm that “READY” is displayed.
3. Turn the power OFF.
4. Replace another board that requires replacement.
• When the HDD requires replacement, see “6.2.3Precautions and procedures when replacing the

the SYS board”.
