Ambrogio L60 Elite: No signal / perimeter signal

What this fault means

Robot cannot detect the perimeter signal.

Safety: Stop the mower and follow the manufacturer safety instructions before physical inspection.

Step-by-step checks

1. Confirm charging/base transmitter has power.
2. Inspect perimeter wire connections and likely break points.
3. Check whether signal is missing everywhere or only locally.
4. Use a short known-good loop where appropriate to isolate installation vs robot receiver.
5. If a known-good loop still gives No signal, arrange receiver/base electronics diagnosis.
