* : For more information 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 [0] on the operation panel with the SP selection menu displayed, you will
see detailed information about the recently logged SC990 or SC991 errors, including
the software file name, line number, and so on. (1) above is the recommended method,
because another SC could write over the information for the previous SC.
