• Headlight Indicator: Shows if the headlight is on.
• Error Warning: Displays error codes if issues occur.
• Voltage (VOL) & Current (CUR): Battery voltage and current operating current.
• Remaining Mileage (RM): Estimated remaining range.

5.2. Key Introduction and Basic Operations

• Power On/Off: Press and hold the Power button to turn the display on or off.
• Multi-function Display Switch: When the display is on, click the Power button to cycle through ODO, TRIP, VOL, CUR, and TM. ODO is the default display after power-on.
• PAS Level Adjustment: When the display is on, click the '+' button to increase the PAS level (PAS+1) or the '-' button to decrease it (PAS-1). The default is PAS1.
• Front Light Control: When the display is on, press and hold the '+' button to turn the front light on or off (under the normal speed display interface).
• Walk Mode Function: Under the normal speed display interface, when the e-bike is stationary, press and hold the '-' button to enter 6KM/h walk mode. There are two modes:
  • Locked Mode: After pressing the '-' button, the e-bike remains in walk mode even after releasing the button. Press the '-' button again or brake to exit.
  • Non-lock Mode: The e-bike is in walk mode only while the '-' button is pressed.
• Speed Mode Display: On the normal speed display interface, press and hold the '+' button and '-' button simultaneously to cycle through average speed, maximum speed, and real-time speed. The default display is real-time speed.

6. Settings

To enter the settings menu, press and hold the '+' and '-' buttons simultaneously. Use the Power button to navigate between parameters (P01-P20). Use the '+' button to increase values and the '-' button to decrease values. To save changes and exit, press and hold the '+' and '-' buttons again. If no action is taken, the system will automatically exit and save settings after 8 seconds.

6.1. Parameter Descriptions

• P01: Backlight Brightness: Level 1 (darkest) to Level 3 (brightest).
• P02: Mileage Unit: 0 = KM, 1 = MILE.
• P03: Voltage Level: Set the voltage of your e-bike (e.g., 24V, 36V, 48V, 60V).

7. Maintenance

To ensure the longevity and optimal performance of your M6C display, follow these maintenance guidelines:

• Cleaning: Regularly wipe the display screen with a soft, damp cloth. Avoid using abrasive cleaners or solvents that could damage the screen or casing.
• Protection: While the display is IP65 waterproof, avoid submerging it in water or exposing it to high-pressure water jets.
• 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.
• Connection Check: Periodically check all cable connections to ensure they are secure and free from corrosion or damage.

8. Troubleshooting

If you encounter issues with your M6C display, refer to the following common problems and solutions:

8.1. Error Codes

The display may show error codes to indicate specific problems:

9. User Tips

• Protocol Compatibility: The M6C display uses the UART2 communication protocol. It is crucial to verify that your e-bike's controller also supports UART2 to ensure proper functionality and avoid compatibility issues. If your controller uses a different UART variant (e.g., Bafang, KDS), the display may not work.
• Speed Limit Settings: The default speed limit setting on the M6C is typically unlimited (set to 100). If your e-bike's controller has its own speed limit, the display will only show the speed allowed by the controller, regardless of the display's setting.
• Adjusting Speed Limit (P08): To change the speed limit, long press the '+' and '-' keys simultaneously to enter the menu. Short press the Power button to navigate to P08. Use the '+' key to set your desired speed. After adjusting, long press the '+' and '-' keys again to save the setting and exit the menu.
