Vehicle Status Display Area
Vehicle Status Code Meaning：

Setting

1.  Backlight brightness, level 1 darkest, level 3 brightest;
2. mileage unit, 0: KM; 1: MILE;
3. Voltage level: 24V, 36V, 48V, 60V, 64V default 36V;
4. Dormancy time: 0, not dormancy;
   • Other numbers are dormancy times, range: 1-60; Unit minutes;
5. Help file bit: 0, 3
   • file mode: 1,5 gear mode:
6. Wheel diameter: unit, inch;
   • Precision: 0.1;
   • This parameter is related to the meter display speed and needs to be entered correctly;
7. Speed gauge magnetic steel number : range: 1-100;
   • This parameter is related to the meter display speed and needs to be entered correctly;
   • If it is an ordinary hub motor, direct input of magnetic steel;
   • If it is a high-speed motor, it is also necessary to calculate the deceleration ratio, and the input data = the number of magnetic steel × deceleration ratio;
   • For example: number of motor magnets 20, deceleration ratio 4.3: input data is: 86 = 20 × 4.3
8. Speed limit: range 0-100km / H, 100 means no speed limit,
   • The input data here represents the maximum operating speed of the vehicle: for example, input 25, indicating that the maximum operating speed of the vehicle will not exceed 25km/h; Drive speed maintained at set value,
   • Error: ± 1km/h; (Speed limit for power and steering)
   • Note: The value here is based on kilometers. When the unit setting is converted from kilometers to miles, the speed value of the display interface automatically converts to the correct mile value, but the speed limit value set at this menu under the mile interface is not converted. Is inconsistent with the actual speed limit of the mile speed;
   • Note: P09-P15 menu is only valid in communication state
9. zero start, non-zero start setting, 0: zero start; 1: Non-zero start;
10. The drive mode is set to 0: Power Drive(how much power is output is determined by the power file bit, and the switch is invalid).
11. Electric drive(by turning the handle drive, when the power file bit is invalid).
12. Power Drive and Electric Drive Coexistence
13. Help sensitivity setting range: 1-24;
14. Help start intensity setting range: 0-5;
15. Power Magnetic Steel Disk Type Setting 5, 8, 12 Magnetic Steel Types
16. Controller limit value set default 12A range: 1-20A
17. Controller undervoltage
18. ODO zero setting length press key 5 seconds ODO zero
19. :0: No enabling cruising, 1: enabling cruising; Automatic cruise optional(valid for protocol 2 only)
20. Display speed ratio adjustment range: 50 % ~ 150 %,
21. 0 power bit, 0: 0, 1: does not include 0
22. :0:2 Protocol 1:5 S Protocol 2: Standby 3: Standby

Key Introduction

• Press the button to use the brief
• Key operation is divided into short press and long press, and combination key length press
• Short press is used for rapid/frequent operations, such as the specific key combination position as follows
  1. When riding, you need to modify the power/speed file, short press
  2.  Toggle display data for multi-function areas during cycling, short click
• Single key length is mainly used to switch the mode / switch state
• Composite keys(long presses) are used to set parameters because the operation is complex, which can reduce errors
• (Short press does not make the composite key, because it is easy to trigger mistakenly, so it is too difficult to do）
  Specific operational explanations:

modify the power ratio / power file
Let’s say the current is power mode.

1. Short press ， Help + 1
2. Short press ， Help – 1

Toggle speed display
Long press, + Toggle speed display

Set / Disable 6Km/h Cruise, Switch Headlight, ODO Clear Zero
Static state of vehicles，long press ，Will enter 6KM/h cruise mode, let go of cruise mode;long press Turn
the lights on and off； P16Menu Interface,  long press five seconds，ODO clear zero。

Switching liquid crystal display
If the current display is working，long press Will turn off the screen, insteadturnon the screen

Toggle multi-function display area content

Short  Can switch the value of the multifunction display area

Set Parameters

• Long press +  Will enter the parameter setting interface. Parameters that can be set include,Wheel diameter(in: inches), number of magnetic steel, liquid crystal brightness,, low pressure points, etc.(see settings: P01-P20)；
• Under Settings Interface，Can be short press or Set the value to perform a minimum-precision unit value operation，you can also long press or Continuous Fast Modify Parameters：

Short press Switch to Next Parameter；Exit settings and save parameters. If not operated, the modified parameters will automatically exit and be saved after 8 seconds

Note: due to the upgrade of the company’s products, the content of the product will be different from the specifications, but it will not affect your normal use.
