Advanced Settings

P01 Brightness. 1 is the darkest, 3 is the brightest


P02 Unit of the mileage. 0 is KM, 1 is MILE


P03 Voltage grades. 24V, 36V, 48V. The original voltage is 36V.

P04 Sleep time. 0 is without sleep, other numbers stand for the sleep time (1-60 min).

P05 PAS grades. 0, 3 grades mode: 1 grade 2V, 2 grade 3V, 3 grade 4V
1, 5 grades mode: 1 grade 2V, 2 grade 2.5V, 3 grade 3V, 4 grade 3.5V, 5 grade 4V

P06 Wheel size. Unit: inch. Precision: 0.1


P07 Speed measuring magnet. Range: 1-100


P08 Speed limit. Range: 0-50km/h, 50 means without limit
No-Communication Status (controlled by the meter): when the real speed is over the ones
we set, the meter would shut off PWM output; when less than the speed we set, the meter
would turn on PWM output automatically, the driving speed would be ±1km/h; (Speed limit
is for PAS, not for Throttle)
Communication Status (controlled by the controller): The driving speed keeps same with theones we set. Random error: ±1km/h. (Speed limit is for both PAS and Throttle)
Notes: These data are based on KM. When changing KM to Mile, the speed value on thescreen would convert to correct Miles automatically, but if you do not change the settingof
speed limit from KM to Mile, it would be different from the real speed limit in Mile.


P09 Zero start & Non-zero Start. 0 is Zero Start, 1 is Non-zero Start


P10 Driving mode. 0 is driven by PAS. Throttle is useless at this time. 1 is driven by Throttle. PAS is useless at this time. 2 is driven by PAS & Throttle. Throttle is useless at Zero Start status.

P11 PAS sensitivity. Range: 1-24


P12 PAS start strength. Range: 0-5


P13 PAS magnet type. There are 3 types: 5, 8, and 12.

P14 The Current-limiting of Controller. The original Current is 12A. Range:1-20A


P15 Not implemented now.

P16 Reset ODO. Long press for 5s, ODO could be reset.

Button Introductions
5.1 During riding, need change PAS/Speed grades, shortly press
5.2 During riding, need change data in Multi-function Area, shortly press ;
Long press , could switch status between MODE and ON/OFF;
Long press as a compound button, is mainly used for parameter setting, which could reducemisoperation due to complicated operation. (No compound button with short-time press, because it’s difficult to operate.)
5.3 Specific operation explanations
5.3.1 Change PAS grade
Suppose it’s PAS mode now, shortly press , PAS grade +1
shortly press , PAS grade -1
5.3.2 Shift the speed display
Long press + , to shift the way of speed display
5.3.3 ON/OFF 6KM/H cruising, ON/OFF Headlight, Reset ODO
When e-bike stops, long press to enter 6KM/H cruising mode. Stoppressing to exit the cruise mode;
Long press to turn ON/OFF Headlight;
At P16, long press for 5s to reset ODO. 5.3.4 ON/OFF the screen
Long press to turn ON/OFF the screen. 5.3.5 Change data in multi-function Area
Shortly press to change data. 5.3.6 Parameters setting
Long press + to start setting parameters, such as wheel
size(inch), background luminance… (Refer to P01-P16)
On the setting interface, shortly press , or to plus/minus
value. Parameters would be shining after modifying, choose the ones you prefer, a. Long press to save the value, the shining would stop. b. Shortly press to shift to the next parameter, and to save current values
at the same time. c. Press + to exit setting parameters and to save values. If
not press these buttons, it would exit and save parameters modified automatically 10s
later
