For more details about 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 SC991, including the software file
name, line number, and so on. Of these two methods, 1) is the recommended method,
because another SC could write over the information for the previous SC.
