Robot lawnmower shows E11 and stops; display may indicate 'Outside working area'.

Safety first: Turn off the mower before moving it back into the lawn area.

• Return mower inside loop: Place the Hyundai mower well inside the boundary and restart. If E11 clears, the mower was simply outside the loop.
• Check boundary layout: Ensure the wire is not run parallel and close to metal fences, buried cables, or steel edging. Increase the distance or change the route if interference is suspected.
• Verify guide wire connection: If your Hyundai model uses a separate guide wire, confirm it is connected to the correct terminals on the base and not crossed with the boundary wire.
• Adjust narrow passages: In tight corridors, ensure the boundary wires are spaced according to the manual so the mower can still detect the signal.
• Monitor for pattern: If E11 occurs repeatedly in the same area, re-route the boundary wire around that section.
