Segway Navimow X390: Error 6105 — Out of Boundary

What this fault means

The mower position is outside or inconsistent with the mapped work area.

Safety: Stop the mower and follow the manufacturer safety instructions before physical inspection.

Step-by-step checks

1. Place the mower on open, flat ground clearly inside the mapped boundary.
2. Allow positioning to stabilise before clearing the error.
3. Check recent map edits, charging-station relocation and correction service state.
4. If the physical mower is inside but the app position is displaced, treat it as positioning/map state rather than moving the boundary to match the error.
5. Escalate persistent offset with screenshots, firmware and map details.
