(11) CPU VERSION/CHECK SUM/PORT INFO/EXIT DIAG

The check sum, version and port setting of main CPU/DSP CPU are displayed.
The signal is EFFECT OFF.
Operating the submenu will finish self-diagnosis, and ordinary operation mode will be restored.
The suffix letter ("A" in the following) of version indication is for compatibility of communications between the main and
DSP microprocessors.
Combining microprocessors with different suffixes will make normal operation impossible.
