    • Driving Speed
    • Single Mileage (TRIP)
    • Accumulated Mileage (ODO)
    • Riding Time
    • Steering Gear Boost
    • Engine Power and Temperature
    • Battery Voltage and Charging Status
    • Braking Status
    • Ambient Temperature

4.3 Parameter Settings

The display allows for various user parameter settings. Accessing and adjusting these settings typically involves a combination of button presses (e.g., long-pressing two buttons simultaneously). Refer to your e-bike's main controller manual for specific instructions on entering and navigating the settings menu.

Adjustable parameters may include:

  • Motor parameters
  • Speed measurement parameters
  • Speed limit parameters

5. Maintenance

  • Cleaning: Wipe the display screen with a soft, damp cloth. Avoid using abrasive cleaners or solvents that could damage the screen or casing.
  • Water Exposure: While the display is IP65 waterproof, avoid submerging it in water. Ensure the USB port cover (if present) is securely closed when not in use, especially in wet conditions.
  • Connection Check: Periodically check that the 6PIN connector is securely attached and free from dirt or corrosion.
  • Storage: When not in use for extended periods, store the e-bike and display in a dry, cool place away from direct sunlight.

6. Troubleshooting

6.1 E10 Error Code

If the display shows "E10" after connecting, this indicates a communication issue. There are two primary possibilities:

  1. Incompatible Communication Protocol: The communication protocol between the P3C display and your e-bike's controller may be incompatible. Ensure your controller supports the UART #2 protocol.
  2. Vehicle System Malfunction: The overall condition of the vehicle may be poor, potentially affecting components such as the boost controller, throttle knob, or motor. These issues can lead to communication failure with the display.

Recommended Actions:

  • Verify the communication protocol compatibility with your e-bike's controller manufacturer.
  • Inspect all connections for looseness or damage.
  • If the issue persists, consult a qualified e-bike technician to diagnose potential problems with the controller, motor, or other related components.

6.2 General Troubleshooting Tips

  • Display Not Powering On: Check all power connections, including the 6PIN connector, to ensure they are secure. Verify that your e-bike's battery is charged and providing power.
  • Incorrect Speed/Mileage Readings: Ensure the wheel circumference setting in the display's parameters is correctly configured for your e-bike.
  • Buttons Unresponsive: Check for any physical obstructions or damage to the buttons. If the issue persists, a factory reset (if available and documented in your controller manual) might be necessary, or contact support.
