5. Maintenance

To ensure the longevity and optimal performance of your BAFANG DPC18 display, follow these maintenance guidelines:

  • Cleaning: Wipe the display screen and body with a soft, damp cloth. Do not use abrasive cleaners, solvents, or spray water directly onto the unit.
  • Water Resistance: While the display is IPX5 waterproof (protected against low-pressure water jets from any direction), avoid submerging it in water or exposing it to high-pressure water sprays (e.g., from a pressure washer). Always ensure the USB port cover is sealed when not in use to maintain water resistance.
  • Cable Connections: Periodically check all cable connections for tightness and signs of wear or damage. Loose connections can lead to intermittent functionality.
  • Storage: When storing your e-bike for extended periods, especially in cold conditions, it is advisable to remove the display and store it indoors in a dry, temperate environment.
