Maintenance

To ensure the longevity and proper functioning of your Bafang C961 display, follow these maintenance guidelines:

• Cleaning: Wipe the display screen and body with a soft, damp cloth. Avoid using abrasive cleaners or solvents that could damage the acrylic material or electronic components.
• Protection: The display is rated IP 65 for protection against dust and water splashes. While it is robust, avoid submerging the display in water or exposing it to high-pressure water jets.
• Connections: Periodically check all cable connections, especially the 5-pin waterproof plug, to ensure they are secure and free from dirt or corrosion.
• Storage: When not in use for extended periods, store the bicycle and display in a dry, temperate environment to prevent damage from extreme temperatures or humidity.

Troubleshooting

The C961 display is designed to be reliable, but should an issue arise, the display can provide error codes to assist in diagnosis.

• Error Codes: If something goes wrong with the system, an error code will flash on the display. Refer to your Bafang motor kit's comprehensive manual for a list of specific error codes and their corresponding solutions. Common issues might include sensor malfunctions, communication errors, or motor faults.
• Display Not Powering On:
  • Check battery charge level.
  • Ensure all electrical connections, especially the 5-pin plug, are firmly seated.
  • Verify the power button on the controller is functioning correctly.
• Inaccurate Battery Level:
  • Ensure your battery voltage matches the display's optimal setting (48V for best accuracy). While 36V and 52V batteries work, the indicator may be less precise.
• No Speed Reading:
  • Check the speed sensor and its magnet on the wheel for proper alignment and function.
