Issue meaning
What this issue means
A2 cannot establish an accurate position when the top radar/LiDAR is dirty, the mower is in a poor starting location, or the charging station has moved outside the mapped area.
Start here
First checks
Clean the top radar/LiDAR with the supplied lint-free cloth and dry it. Move the mower to an open area within the map and retry. If positioning does not recover, use manual mowing in the app to guide it back to the charging station and restart. Confirm the station has not been moved outside the map boundaries.
Inspection
Area to inspect
Top radar/LiDAR cleanliness, starting position and charging-station position relative to the map.
