Possible Causes
RTK base station powered off, RTK antenna obstructed by buildings or trees, Loose RTK antenna cable, Faulty RTK receiver module in mower
How to Fix / Troubleshooting
Safety: No special electrical hazard, but keep mower powered OFF while moving antennas or base units.
- Check RTK base: Ensure the Mammotion RTK base station is powered, with status LEDs indicating normal operation.
- Relocate base: Place the RTK base in an open area with clear sky view, away from tall buildings, trees, and metal structures.
- Inspect antenna cable: Verify the RTK antenna cable is firmly connected at both the base and the mower (if external). Look for cuts or crushed sections.
- Wait for fix: After powering everything, allow several minutes for the RTK/GPS system to acquire satellites.
- App settings: In the Mammotion app, confirm the mower is paired with the correct RTK base and that region settings are correct.
- If E011 continues in open sky with a known-good base, the mower's RTK receiver module may be defective.
