5. Bluetooth Connection & App Setup
The H6C-2 display features Bluetooth connectivity for enhanced control and data management via a mobile application. Follow these steps to connect:
- Download the App: Search for the 'AI qixing' or 'iRiding' app on your mobile phone's app store (available for both Apple and Android systems).
- Log In/Register: Open the app and follow the on-screen instructions to log in or register a new account. This typically involves entering your email address and a verification code.
- Connect Bluetooth: Ensure your ebike display is powered on and Bluetooth is enabled on your phone. Within the app, initiate the Bluetooth connection process. Select your H6C-2 display from the list of available devices.
- Function Settings: Once connected, the app allows you to access various functions, including finding your vehicle, viewing mileage, vehicle locking/unlocking, and other customizable settings. The actual features may vary based on the app version.


6. Operating Instructions
The H6C-2 display provides comprehensive metrics and controls for your ebike:
- Main Display: Shows current speed (KM/H), PAS level, battery charge (E-F bar), ODO (odometer), and trip mileage.
- Indicators: Includes icons for Bluetooth connection, headlight status, and walking mode.
- USB Charging: The display features a USB interface (5V/500mA) that can be used for emergency charging of mobile phones or other small devices.


Adjusting Speed Settings
To change the speed setting on your display:
- 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.
- Once adjusted, long press the '+' and '-' keys again to save the setting and exit the menu.
7. Maintenance
- Cleaning: Use a soft, damp cloth to clean the display screen. Avoid using abrasive cleaners or solvents that could damage the screen or casing.
- Water Resistance: The display is rated IP67 for water and dust resistance, meaning it can withstand splashes and brief immersion. 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 any signs of wear, damage, or loose connections.
8. Troubleshooting
If you encounter issues with your H6C-2 display, refer to the following common problems and solutions:
E10 Error Displayed
If the display shows 'E10' after connection, this indicates a communication issue. There are two primary reasons:
- Incompatible Communication Protocol: The H6C-2 display uses the UART2 protocol. If your ebike controller uses a different protocol (e.g., Bafang, KDS, or other UART variants), the display will not function correctly.
- Poor Vehicle Condition: Issues with the ebike's boost controller, throttle, or motor can interfere with communication to the display, leading to an E10 error.
Solution:
- Verify that your ebike controller supports the UART2 communication protocol. Check your controller's manual or contact its seller for confirmation.
- Inspect other ebike components for faults that might affect communication.


Speed Limit Issues
If you are unable to adjust the speed limit, it depends on whether the speed limitation is imposed by the controller or the display. If the controller limits the speed, the display cannot override it. If the display limits the speed, it can be adjusted via the P08 setting as described in Section 6.
9. User Tips
- Protocol Verification: Before purchasing or installing, always confirm that your ebike's controller uses the UART2 protocol. You can often find this information in the controller's manual or by contacting the controller's seller.
- App Compatibility: The companion app is compatible with both Apple and Android mobile operating systems, so phone model restrictions are not an issue.
- Speed Adjustment: Remember that speed limits can be adjusted through the display's P08 setting if the limitation originates from the display itself.
10. Certifications
The H6C-2 Ebike Display holds the following certifications, ensuring its quality and compliance with international standards:
- CE (Conformité Européenne)
- RoHS (Restriction of Hazardous Substances)
- IP67 (Ingress Protection - Dust tight and protected against immersion up to 1m)
- SGS (Société Générale de Surveillance)
