Usage Features
The DR23 display is designed for intuitive and user-friendly operation:
- Button Interface: Features three buttons (ON/OFF, UP, DOWN) for navigation and control.
- Switching E-bike System ON/OFF: A 1-second press of the ON/OFF button turns the e-bike system on or off. The system automatically switches off after 15 minutes of inactivity.
- Display Interface Cycling: Pressing the ON/OFF button cycles through various display functions: ODO, Trip, Motor Power, Max. Speed, and Avg. Speed.
- Push-Assistance Activation: Press and hold the DOWN button for 1 second to activate push-assistance at 6 km/h. Releasing the button deactivates it. This function is intended for use when pushing the e-bike, not while riding.
- Lighting Control: A 1-second press of the UP button turns the headlights on or off, simultaneously adjusting the display backlight brightness.
- Assist Level Adjustment: Use the UP/DOWN buttons to switch between assist levels (0-5) while riding.
- General Settings Access: Pressing the ON/OFF button from the wheel diameter setting interface accesses the speed limit setting.
- TRIP Clear Function: In TRIP mode, pressing the UP and DOWN buttons simultaneously for more than 1 second clears the trip data.
- Settings Confirmation and Exit: Short pressing the ON/OFF button confirms input in settings interfaces. Holding the ON/OFF button stores settings and exits the current setting.
Maintenance Features
The DR23 display incorporates features and guidelines to ensure its longevity and proper functioning:
- Error Code Indication: The display continuously monitors e-bike system components and indicates errors with specific codes (e.g., Torque Zero Error, Speed Sensor Error, Battery Low Voltage). Users are advised to have the display inspected and repaired by an authorized bicycle dealer when an error code appears.
- Connection Layout: The display uses a Julet Male 6-pin connector for secure and reliable connection to the e-bike system. The wire sequence table provides details for BAT (Battery power), GND (Ground), DTX (Data transmission), DRX (Data receiving), ON-OFF (Controller power control), and Walk (Push control).
- Water-proof Connectors: The display's wire connections are equipped with water-proof connectors, preventing users from seeing the pin wire colors but ensuring protection against moisture.
- Warranty Scope: A 24-month warranty is provided for products used under normal conditions, starting from shipment or delivery.
- Exclusions from Warranty: The warranty does not cover damages resulting from demolition, wrong installation or operation, broken shell after leaving the factory, broken cables, expiry of the warranty period, or force majeure events (e.g., fire, earthquake).
- Warnings: Users are cautioned to use the display with care, avoid connecting/disconnecting when the battery is powered on, prevent hitting the display, refrain from modifying system parameters to avoid disorder, and seek repair when error codes appear.
- Software Versions: The display shows both controller software version (CLS) and display software version (DPS). The controller version is reported by the controller and cannot be adjusted from the display, while the display software version is also not adjustable and is determined by the software itself.
