Unit β€” no equipment selected β€” scoped to this unit only

What are you troubleshooting?

Describe a symptom, error code, or install step. Answers are quoted from this unit's loaded documents β€” never invented.

Photo scan reads codes, nameplate model & part labels via on-device OCR, then searches your docs β€” it does not visually diagnose damage.
Answers are quoted from loaded documents only β€” nothing is inferred. Confirm the model & serial on the nameplate match the selected unit, and verify every spec against the OEM manual. If it isn't in the docs, consult the OEM or a Maxim senior technician.
