8. Settings
   1. P01: Backlight Brightness (1: darkest; 3: brightest)
   2. P02: Mileage Unit (0: KM; 1: MILE)
   3. P03: Voltage Class 24V / 36V / 48V
   4. P04: Sleep Interval
      (0: never, other value means display sleep interval) Unit: minute
   5. P05: Power Assist Gear
      0/3 Gear Mode: Gear 1: 2V Gear 2: 3V Gear 3: 4V
      1/5 Gear Mode: Gear 1: 2V Gear 2: 2.5V Gear 3: 4V Gear 4: 3.5V Gear 5: 4V
   6. P06: Wheel Diameter Unit: inch Precision: 0.1
   7. P07: Magnet Steel Number (for Speed Test) Range: 1-100
   8. P08: Speed Limit
      Range: 0-50km/h, parameter 50 indicates no speed limit.
      1. Non-communications status (panel-controlled)
      When the current speed exceeds the speed limit, the PWM output will be shut down; when the current speed falls to lower than the speed limit, the PWM output will be activated and the driving speed will be set as the current speed ± 1km/h (only applies to assist power speed, not applicable to the handlebar speed).
      2. Communications status (controller-controlled)
      The driving speed will be kept constant as the limited value.
      Error Value: ±1km/h (applicable to both the assist power/handlebar speed)
      Note: The above-mentioned values are measured by metric unit (kilometers).
      When the measuring unit is switched to imperial unit (mile), the speed value displayed on the panel will be automatically switched to corresponding imperial unit, however the speed limit value in the imperial unit interface won’t change accordingly.
   9. P09: Direct Start / Kick-to-Start Setting
      0: Direct Start
      1: Kick-to-Start
   10. P10: Drive Mode Setting
       0: Power Assist – The specific gear of the assist drive decides the assist power value. In this status the handlebar does not work.
       1: Electric Drive – The vehicle is driven by the handlebar. In this status the power gear does not work.
       2: Power Assist + Electric Drive – Electric drive does not work in zero-start status.
   11. P11: Power Assist Sensitivity Range: 1-24
   12. P12: Power Assist Starting Intensity Range: 0-5
   13. P13: Power Magnet Steel Number 5 / 8 / 12pcs
   14. P14: Current Limit Value: 12A by default; Range: 1-20A
   15. P15: Unspecified
   16. P16: ODO Zero-Out
       Long press the up key for 5 seconds and ODO value will be erased.

Operations

Arrangement of Keys

Introduction of Keys
Key operations involve short press, long press and long press of combination keys.
Short press is used for short/frequent operations as:

Long press on a single key is used to switch mode/on/off status.
Long press on combination keys to set parameters, which can avoid misoperations (short press on combination keys is disabled to avoid misoperation).

Instructions of Keys

Adjust PAS level / Throttle level
In PAS mode

a. Short press , PAS +1.
b. Short press , PAS -1.

Switch Speed Display

Long press + to switch speed display type.
Enable/Disable 6km/h walk boost mode, set real-time cruise and turn on/off the lights

When the vehicle is parked, long press to enter 6km/h walk boost mode. When the vehicle is travelling, long press to enter real-time cruise mode.
Long press to exit the cruise mode when the vehicle is in cruise 7 mode.
Long press to turn on/off the lights.

Turn on/off the LCD Panel
When the display is in operation, long press and it will be turned off, otherwise it will be turned on.

Switch Displayed Readings in Multi-Function Section
Short press to switch readings shown in the multi-function section.

Set Parameters
Long press + to enter the setting interface.

Customizable parameters include:
Wheel Diameter (unit: inch);
Magnetic Steel Number;
Backlight Brightness;
Low Voltage Threshold (refer to setting P01-P14)

In the setting interface, short press or to turn up/down value to the parameter, which will blink after modified. After selecting the parameter that needs to be set,

• Long press to save the current value, and the parameter will stop blinking;
• Short press to switch to the next parameter and the previously set value will be saved at the same time.

Press + to exit the setting and save the parameters.
Without this operation, the system will automatically exit and save the modified parameters after 10 seconds.

Note: Due to product upgrade, the product you purchased may be slightly different from the descriptions in this user manual, and this won’t affect normal usage.
