2.9 Parameters setting
P01 Background luminance: 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 48V.
P04 Sleep time. 0 is without sleep, other numbers stand for the sleep time (1-60 min).
P05 PAS grades. 0-3, 0-5(default) or 0-9 modes for choice
P06 Wheel size. Unit: inch.
Precision:
P07 Speed measuring magnet. Range: 1-255
P08 Speed limit. Range: 0-100km/h, 100 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 weset, the meter would turn on PWM output automatically, the driving speed
would be ±1km/h (Speed limit is both for PAS and Throttle)
Communication Status(Controlled by the controller):
The driving speed keeps the same with the ones 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 the
screen would convert to correct Miles automatically, but if you do not change the setting of
speed limit from KM to Mile, it would be different from the real speed limit in Mile.
2.8 PAS grades
PAS Status (0-9 grades), Cruise mark
2.Press:
2.6 Speed
Real speed(SPEED), Maximum speed(MAX), Average speed(AVG),
MPH,KM/Hare both optional.
According Wheel size and signal data, the meter could figure out the real speed.

3.2 During riding, need change data in Multi-function Area, shortly press "M"; Long press "M",could
switch status between MODE and ON/OFF;
Long press as a compound button, is mainly used for parameter setting, which couldreduce
misoperation due to complicated operation. (No compound button with short-time press,
because it's difficult to operate.)
3.3 Specific operation explanations
3.3.1 Change PAS grade
Suppose it's PAS mode now,shortly press " A ", PAS grade +1, shortly press"V",PAS grade-1.
3.3.2 Shift the speed display
Long press "M"+ " A ", to shift the way of speed display
3.3.3 ON/OFF 6KM/H cruising, ON/OFF Headlight, Reset ODO
When e-bike stops, long press " V" to enter 6KM/H cruising mode. Stop pressing to exit
the cruise mode; Long press " A " to turn ON/OFF Headlight and Taillight; At P16, long
press ''V"for 5s to reset ODO.
3.3.4 ON/OFF the screen
Long press "M" to turn ON/OFF the screen.
3.3.5 Change data in multi-function Area.
Shortly press "M" to change data.
3.3.6 Parameters setting
Long press " A " + " V" to start setting parameters, such as wheel size(inch),
background luminance...(Refer to P01-P16)
On the setting interface, shortly press " A ", " V" or to plus/minus value. Parameters
would be shining after modifying, choose the ones you prefer,
a. Long press "M" to save the value, the shining would stop.
b. Shortly press "M" to shift to the next parameter, and to save current values
at the same time.
c. Press " A " + " V" to exit setting parameters and to save alues.If not press
