2.3 Display Content

The display shows all the following content within 1 second of powering on, including the software version number.

3. Display Content Description

3.1 Voltage Status Level (POWER)

3.2 Multi-function Display Area

• Total mileage (ODO)
• Single trip mileage (TRIP)
• Real-time voltage (V)
• Operating current (A)
• Running time (TIME)
• Fault code (E)

3.3 Fault Status Display Area (E)

When a fault symbol  appears, briefly press the ON/OFF button to switch to the E interface. The corresponding number on this interface represents the specific fault condition as follows:

• ERROR 1: Motor Hall sensor fault
• ERROR 2: Brake fault
• ERROR 3: No fault
• ERROR 4: No fault
• ERROR 5: No fault
• ERROR 6: Under-voltage fault
• ERROR 7: Motor phase line fault
• ERROR 8: Torque fault
• ERROR 9: Controller fault
• ERROR 10: Signal reception fault
• ERROR 11: Signal transmission fault

3.4 Speed Display Area

• Unit: mile, KM/H
• The speed signal is obtained from the Hall sensor inside the motor and sent to the instrument via the controller.
• The instrument calculates the actual speed based on the wheel diameter and signal data (the number of magnetic poles in the motor must also be set).

3.5 Gear Display Area

• Briefly press the MODE button to cycle through the gears. The higher the gear, the faster the speed.

3.6 Cruise Control Display Area

• After the motor starts, maintain the throttle for about 8 seconds to activate the cruise control symbol. The motor will maintain the current speed after releasing the throttle.
• Braking or adjusting the throttle again will deactivate the cruise control.

3.7 Start Mode Selection Display Area

• Non-zero start: NON symbol lights up
• Zero start: ZERO symbol lights up

3.8 USB Charging Icon Display Area

• When a data cable is connected to the USB port and draws more than 100 mA, the USB icon lights up.
• If the icon is flashing, it indicates intermittent charging or a load current exceeding 1000 mA, and the USB port will automatically enter protection mode.

4. Parameter Settings and Definitions

ODO Reset: Long press the MODE button in the ODO parameter setting interface to reset ODO.

5. Button Functions

5.1 Power Off State

• Long press the power button to turn on the device.
• Briefly press the power button to switch between ODO, TRIP, VOL, fault code, current, Hall value, and running time interfaces.

5.2 Power On State

• Long press the power button to turn off the device.
• Briefly press the MODE button to switch gears.
• Long press the MODE button to control the headlight on/off.

5.3 Normal Operation State

• Simultaneously long press the power button and MODE button to enter the menu settings.
  • Briefly press the power button to switch between menus.
  • Briefly press the MODE button to edit the parameters in the current menu (default is incremental; long press the power button to switch between increment and decrement).
