Robot mower sometimes stops with the message or indication that it is outside the working area, but the boundary wire is intact.

Safety first: Unplug the charging station before modifying the boundary wire.

• Check wire depth: Ensure the boundary wire is laid at the depth recommended by Parkside (usually on the surface or shallowly pegged, not deeply buried).
• Move away from interference: If the wire runs parallel to mains cables, metal fences, or steel edging, move it further away if possible.
• Check base output: Verify the base LED indicates a strong loop signal. If weak, the transmitter board may be failing.
• Reduce loops and spurs: Avoid unnecessary loops or long spurs of wire that can confuse the mower.

When to replace: Replace the charging station boundary transmitter if the signal is weak despite a good wire layout.
