Kress KR120E Mission: Virtual boundary / no-go problem

What this fault means

The mower follows a route outside the intended virtual boundary or mishandles a no-go area.

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

Step-by-step checks

1. Confirm positioning quality before editing boundaries.
2. Verify the map has not shifted and station/reference geometry is unchanged.
3. Supervise a short repeat test at the exact location.
4. Increase virtual clearance from physical hazards if the map itself is correct.
5. Report reproducible software/map behaviour before rebuilding a large installation.
