E1 Outside Working Area means Landroid detects a loop signal but believes it is on the wrong side of it. Place the mower well inside the loop, verify terminal direction, inspect crossed wire and islands, and try a short simple test loop. Reversed connections, crossed wire, incorrectly wired islands, weak signal, interference, or a mower

E1 Wire Missing means a wired Landroid cannot detect a usable boundary-loop signal. The break may be in the wire, a connector, the base power supply, or the mower’s signal detection. Quick answer: Check the charging base light and power first, then test the boundary loop with a short known-good wire. Repair outdoor connections only
