STIGA A 25v: RTK / reference connection lost

What this fault means

The autonomous robot loses the correction-data path needed for precise navigation.

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

Step-by-step checks

1. Confirm robot and reference-station power.
2. Check 4G/data connectivity used between mower/service/reference setup.
3. Improve sky view and verify no new obstruction around the reference installation.
4. Confirm the reference station has not moved.
5. Avoid remapping until RTK position is stable again.
