9. Troubleshooting

• Display not turning on / Remote not responding: Ensure all connections are secure and the 5PIN female connector is correctly seated. Check for any visible damage to wires or connectors.
• Display shows no speed/mileage/battery: Verify that all necessary connections, including the assistant sensor, are properly installed and connected to the controller. Ensure the display is compatible with your specific BAFANG motor model.
• Speed limit issues (e.g., stuck at 25-26 km/h): Check the speed limit setting in the display's advanced parameters. Adjust the speed limit to your desired value (e.g., 99 km/h for full speed) if allowed by local regulations.
• Display heating up but not turning on: This could indicate a wiring issue or a fault with the display itself. Disconnect power immediately and re-check all connections. If the issue persists, contact support.
• Incompatibility with KT controllers: These displays are designed for BAFANG UART protocol motors and are generally not compatible with KT controllers.

10. Maintenance

• Cleaning: Use a soft, damp cloth to clean the display screen and body. Avoid using harsh chemicals or abrasive materials that could damage the screen or casing.
• Water Exposure: While the displays are waterproof (IP65/IP67), avoid prolonged exposure to heavy rain or submersion. Ensure the Type-C/USB port covers are securely closed when not in use.
• Storage: When not in use for extended periods, store the e-bike and display in a dry, cool place, away from direct sunlight and extreme temperatures.
• Firmware Updates: Some models (e.g., 500C) support software upgrades via UART. Check with the manufacturer or seller for available updates and instructions.

11. User Tips

• Check Connector Type: Always confirm your motor has a 5PIN female connector and uses the UART protocol before purchasing a display.
• Voltage Compatibility: Ensure the display's voltage setting matches your e-bike's battery (e.g., 24V, 36V, 48V, 52V).
• Speed Limit Adjustment: If you experience unexpected speed limitations, check the 'Speed limit' setting in the advanced menu.
• Full Functionality: For full display functionality (speed, mileage, battery), ensure all components, including the assistant sensor, are properly connected.
• Password Management: If you set a PIN for startup, remember it. If forgotten, you may need to contact support for assistance.
