4.7 PAS grades
PAS Status (0-9 grades), Cruise mark
4.8 Parameters setting
P01 Background luminance. 1 isthe darkest,3 isthe brightest
P02 Unit ofthe mileage. 0 isKM, 1 isMILE
P03 Voltage grades.24V,36V,48V.The originalvoltage is36V.
P04 Sleep time. 0 iswithoutsleep, othernumbers standforthe sleep time (1-60 min).
P05 PAS grades.
0, 3 gradesmode:1 grade 2V,2 grade 3V, 3 grade 4V
1, 5 gradesmode:1 grade 2V,2 grade 2.5V,3 grade 3V, 4 grade 3.5V, 5 grade 4V
P06 Wheelsize. Unit: inch.Precision:0.1
P07 Speedmeasuring magnet. Range:1-100
P08 Speedlimit. Range:0-50km/h, 50 meanswithoutlimit
No-Communication Status(controlled bythe meter): when the realspeed isoverthe ones
weset,the meterwouldshutoffPWMoutput; when lessthan the speed weset,the meter
wouldturnon PWMoutputautomatically,the driving speed wouldbe ±1km/h;(Speedlimit
isforPAS,notforThrottle)
Communication Status(controlled bythe controller): The driving speed keepssame with the
oneswe set. Randomerror: ±1km/h. (Speed limitisforbothPAS andThrottle)
Notes:ThesedataarebasedonKM.WhenchangingKMtoMile,the speedvalue on the
screen wouldconvert tocorrectMilesautomatically,butif you do notchange the setting of
speed limit fromKMto Mile, it would be differentfromthe realspeed limit in Mile.

P09 Zero start &Non-zero Start. 0 isZero Start, 1 isNon-zero Start
P10 Driving mode.
0 isdriven byPAS. Throttle isuseless atthistime.
1 isdriven by Throttle. PAS isuseless atthistime.
2isdriven byPAS &Throttle. Throttle isuseless atZero Start status.
P11PAS sensitivity. Range:1-24
P12 PAS start strength. Range:0-5
P13 PAS magnettype. There are 3 types:5, 8, and 12.
P14 The Current-limiting ofController.The originalCurrentis12A.Range:1-20A
P15 Notimplemented now.
P16 ResetODO. Long press for5s,ODO could be reset.
5. ButtonIntroductions
5.1 During riding, need changePAS/Speed grades, shortlypress
5.2 During riding, need change data in Multi-function Area, shortlypress ;
Long press , could switch statusbetween MODEand ON/OFF;
Long press asacompound button, ismainlyused forparametersetting, which couldreduce
misoperation due to complicated operation.
(No compound button with short-time press, because it sdifficult to operate.)
5.3 Specific operation explanations
5.3.1 Change PASgrade
Supposeit sPAS mode now,
shortlypress ,PASgrade +1
shortlypress ,PASgrade -1

5.3.2 Shift the speed display
Long press + , to shift the way ofspeed display
5.3.3 ON/OFF6KM/Hcruising, ON/OFFHeadlight, ResetODO
When e-bike stops,long press toenter6KM/Hcruising mode. Stop
pressing to exit the cruise mode;
Long press to turn ON/OFFHeadlight;
AtP16, long press for5storesetODO.
5.3.4 ON/OFFthe screen
Long press to turn ON/OFFthe screen.
5.3.5 Change data in multi-functionArea
Shortlypress to change data.
5.3.6 Parameters setting
Long press + tostart setting parameters,such aswheel
size(inch), background luminance…(RefertoP01-P16)
Onthe settinginterface, shortlypress ,or toplus/minus
value. Parameters would be shining aftermodifying, choose the onesyou prefer,
a. Long press to save the value, the shining would stop.
b. Shortlypress toshift tothenextparameter,and tosavecurrentvalues
atthe same time.
c. Press + toexit setting parameters and tosavevalues.If
notpress thesebuttons,it wouldexit and saveparameters modified automatically10s
later.
