Robomow RC304: Wire / signal problem

What this fault means

The mower cannot detect the perimeter signal reliably.

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

Step-by-step checks

1. Check base/power-box power and perimeter connections.
2. Inspect wire joints and recent garden work for breaks.
3. Determine whether the fault is everywhere or one location.
4. Use a small test loop where supported to isolate the installation.
5. Known-good loop failure points toward mower/base receiver electronics.
