How to Fix / Troubleshooting
Safety first: Keep the mower on a stable surface while adjusting settings.
- Reset time and date: Use the control panel to set the correct time, date, and mowing schedule. Save the settings and restart the mower.
- Power cycle: Turn the main switch OFF for 1 minute, then ON again to reset the electronics.
- Continuous power: Leave the mower in the charging station for several hours to recharge any internal backup supply.
