Defective EEPROM

What does 94 mean?

This fault indicates a permanent hardware defect in the unit's EEPROM (Electrically Erasable Programmable Read-Only Memory), suggesting the memory chip itself is faulty and likely beyond a simple reset or re-parameterization. A defective EEPROM will prevent the unit from reliably storing or retrieving critical configuration data, making consistent and reliable operation impossible. This is a severe hardware failure that typically requires unit replacement.
