*1: There are two possible methods to get more details about SC990 and SC991:
1. Execute SP7403 or print an SMC Report (SP5990) to read the history of the 10 most recent logged
errors.
2. If you press the zero key on the operation panel with the SP selection menu displayed, you will see
detailed information about the recently logged SC990 or SC991, including the software file name,
line number, and so on.
The first method in the above list is the recommended method, because another SC could write over the
information for the previous SC.
