Robot mower's boundary wire LED on the charging station blinks or changes color, but the mower shows no specific error and behaves erratically near the boundary.

Safety first: Disconnect the charging station from mains before working on the boundary wire.

• Inspect splices: Locate all splices in the boundary wire and ensure they are made with proper LandXcape waterproof connectors. Redo any twisted or taped joints.
• Measure resistance: Use a multimeter to measure loop resistance. High resistance indicates thin wire, long runs, or poor connections.
• Shorten loop (test): Temporarily create a smaller loop near the base to see if the LED returns to normal. If so, the issue is in the extended section of wire.
• Reduce interference: Reroute the wire away from metal fences, buried power lines, or other robotic mower wires.
• Upgrade wire: If the installation is very large, consider using a thicker gauge boundary wire compatible with LandXcape systems.
