How to use this index
Copy the display exactly
Spaces, letters, and lookalike characters matter. For example, 5E and SE may be easy to confuse on a segmented display.
Confirm the exact model
Error meanings and access instructions can vary by product family and model revision, even within one brand.
Start with observable checks
A code points to a system. It does not prove which part failed, so compare the symptom before replacing anything.
