Overview
Fault LEDs indicate the device may not be trustworthy for safety monitoring until cleared or serviced. Compare patterns against the authoritative guide for your hardware revision - not a different unit’s memory.
Triage
- Identify model + hardware version.
- Power-cycle once if permitted; re-evaluate pattern.
- Pair to mobile if safe to capture diagnostics/self-test when available.
- If persistent, label and remove from service per policy; escalate with photos/timestamps.
