NOTICE
Damage to the processor
If the CPU is operated with a higher clock frequency than permitted, it can be destroyed.
This leads to data loss.
• Operate the processor only at a clock frequency that is equal to or less than the
permitted clock frequency.
• You should therefore only install an approved processor.
