In the riding mode after 5 seconds, display 2 automatically returns to display 1, and the originalmotor power (MOTOR W) display is replaced with motor operating temperature display (MOTOR ℃) display (the internal motor should be equipped with the temperature sensor and the output of temperature detection signal).
   
4. Display 3
   Hold button shortly in display 2 to enter display 3.
   In the riding condition, five seconds later, a single maximum speed (MXS) display automatically returns to the real riding speed (Km/H).

      	03_info	Motor Hall Signal Abnormality
      	04_info	Torque sensor Signal Abnormality
      	05_info	Axis speed sensor Abnormality(only applied to torque
      	06_info	Motor or controller has short circuit Abnormality

      Electronic control system failure will display (flashing) fault code. Once the fault was removed, it automatically exits from the fault code display interface.

   2. Motor temperature alarm
      When the motor temperature (the internal motor should be equipped with the temperature sensor and the output of temperature detection signal) is over the warning value, MOTOR ℃ (℉) flashes to alarm at any display, meanwhile the motor controller will offer the appropriate protection to motor.

General Project Setting

1. Set maximum riding speed
   After power on for 5 seconds, hold and at the same time, maximum riding speed Km/H and MXS flash, hold or shortly to set the maximum riding speed (default 25Km/H). Hold button shortly and go to the next parameter settings.
   
2. Wheel diameter setting
   The wheel diameter will be set after finishing setting the maximum riding speed, wheel diameter specifications flashes. Hold or shortly to set the specifications of wheel diameter. Select the range 6,8,10,12,14,16,18,20,22,24,26,700c and 28 inches. Hold button shortly and go to the next parameter settings.
