5. Operating Instructions
5.1 Key Introduction
- Power On/Off: Long press the power button to turn the display on or off.
- Gear Adjustment (PAS): Short press the '+' key and '-' key to adjust the gear up and down.
- Function Display Switch: Short press the power key to switch the function display. The display cycles through total mileage, single mileage, current battery voltage, and current current display.
5.2 Display Content Explanation
The H6C-2 display shows various metrics on one page for easy monitoring:
- Speed: Current riding speed (KM/H or MPH).
- PAS (Pedal Assist System): Current assist level.
- Headlight: Indicator for headlight status.
- Battery: Battery level indicator (E to F, with a bar graph).
- Multifunctional Display Area: Shows total mileage (ODO), single mileage (TRIP), battery current voltage (VOL), current operating current (CUR), and error warnings.
5.3 Advanced Functions
- Front Light: When the display is on, press and hold the power key to turn the front light on/off.
- Walk Mode: When the e-bike is stationary, press and hold the '-' button to enter 6KM/h walk mode. This mode can be locked (stays on after release) or non-locked (requires holding the button). To exit, press and hold the '-' button again or brake.
- Speed Mode Display: On the normal speed display interface, press and hold the '+' button and '-' button simultaneously to switch between average speed, maximum speed, and real-time speed. (Default is real-time SPEED).
- USB Interface: The display features a USB port (5V/500mA) for emergency charging of mobile phones.
5.4 Parameter Settings (P-Codes)
To enter settings, press and hold the '+' and '-' buttons simultaneously. Use the power key to switch between parameters and the '+' / '-' keys to adjust values. Press and hold '+' and '-' again to save changes and exit.

6. Troubleshooting
6.1 Error Codes
| Status Code | State Meaning |
|---|---|
| E06 | Battery undervoltage |
| E07 | Motor failure |
| E08 | Throttle malfunctioning |
| E09 | Controller failure |
| E10 | Data receive failure |
| E11 | Data send failure |
6.2 Specific Troubleshooting for E10 Error
If the display shows E10 after connecting, there are two primary possibilities:
- Communication Protocol Incompatibility: The communication protocol between the display (UART2) and your e-bike's controller may not be compatible. Verify that both components use the UART2 protocol.
- Vehicle Component Issues: The overall condition of the vehicle's electrical system might be poor. This could involve issues with the boost controller, knob, or motor, which can lead to communication failure with the display. Inspect these components for any damage or malfunction.
7. Maintenance
- Cleaning: Wipe the display screen and body with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Water Resistance: The display has an IP67 rating, meaning it is protected against dust and temporary immersion in water. However, avoid prolonged exposure to heavy rain or submersion.
- Storage: When not in use for extended periods, store the display in a dry, cool place away from direct sunlight.
- Cable Inspection: Periodically check all cables and connectors for wear, damage, or loose connections.
8. User Tips
- Verify Compatibility: Always double-check that your e-bike's controller uses the UART2 communication protocol before purchasing or installing the H6C-2 display to ensure proper function.
- Correct Parameter Settings: Accurately set parameters like wheel diameter (P06) and magnetic steel number (P07) for precise speed and mileage readings.
- Emergency Charging: Utilize the built-in USB port for convenient emergency charging of your mobile devices during rides.
