• Real-time speed indication: Indicate real-
time speed unit km/h or MPH.
• Intelligent battery capacity indication: Show
the percentage of remaining battery capacity
which accounts for total battery capacity.
• Multiply function indication: It consists of
single-trip distance TRIP, total distance ODO,
remaining distance RANGE, output power
POWER, energy consumption Cal, riding
time TIME. (Note: Within ten seconds, the
display will detect the pedal sensor type, if
torque sensor, then the display will show
the interface of the calorie, if display get
remaining range data, the display will show
the interface of the remaining distance,
otherwise the display will not show the two
interface)

BUTTON DEFINITION
There are three buttons for C15, including
ON-OFF/Mode, Up and Down .
NORMAL OPERATION
“press and hold” means press and hold
for more than two seconds, briefly press
means press for less than 0.5 second.
• ON/OFF
Press and hold power button, the display
starts working. Press and the power button
again, then it turns off. When it is off, the
display doesn’t consume the power, the
leakage current is less than 1uA.
• Turn on the headlight /turn off the
headlight
Turn on the light: When the headlight is
off and press and hold the button “+”,
the luminance of the display backlight will
decrease and the icon of the headlight will
be showed.
Turn off the light: When the headlight is on
and press and hold the button “+”, the lumi-
nance of the display backlight will increase
and the icon of headlight will disappear.
(The interface: headlight has been turned on)
• 6KM/H push assistance
Press and hold the “-” , display will show the
icon “ ” and the E-bike enter into the
mode of push assistance, release the “-” but-
ton, the icon disappear from the display and
the E-bike exit the mode of push assistance.
(The interface: mode of push assistance)

DISPLAY MANUAL DP C15.UART
• Multiple functions interface
After starting up, the default interface is
“TRIP” (single trip distance). Press "Mode"
briefly circularly, it can circularly switch as
“TRIP” (single trip distance) →“ODO”(total
distance) →“MAX”(maximum riding
speed) →“AVG”(average riding speed) →
“RANGE”(remaining distance) →“CALO-
RIES/CAL”(KCal) →“TIME”(riding time) →
“POWER”(output power) →“TRIP”(single trip
distance).
• Error code indication
When the failure occurs, the display will
show the error code and the display will
flicker at the same time. See the detailed
definition shown in the table of the Annex1.
Only when the failure is solved, it can exit
the error code interface. When failure hap-
pens, the rider shall stop riding immediately.
(The interface: error code)

ERROR CODE DEFINITION
This HMI DP C15.UART can indicate all errors
occurring on the pedelec.
Error Explanation Troubleshooting
03 Brakes enabled Check whether a brake cable is stuck.
07 High voltage protection Bring your Pedelec to your dealer or to a
specialist to have the error fixed.
08 Fault with motor hall sensor inside Bring your Pedelec to your dealer or to a
specialist to have the error fixed.
10 The motor temperature reaches to
the max protection value Stop the e-bike for a rest.
12 Fault with current sensor inside
controller
Bring your Pedelec to your dealer or to a
specialist to have the error fixed.
13 Fault with temperature sensor inside
battery
Bring your Pedelec to your dealer or to a
specialist to have the error fixed.
21 Fault with wheel speed detecting
sensor
Bring your Pedelec to your dealer or to a
specialist to have the error fixed.
22 BMS communication fault Bring your Pedelec to your dealer or to a
specialist to have the error fixed.
25 Torque sensor torque signal fault Bring your Pedelec to your dealer or to a
specialist to have the error fixed.
26 Torque sensor speed signal fault Bring your Pedelec to your dealer or to a
specialist to have the error fixed.
30 Communication fault Bring your Pedelec to your dealer or to a
specialist to have the error fixed.
Note: Error Code 10 will probably appear on the
dispaly when the e-bike is climbling for a long
time. This indicates that the motor temperature has
reached the protection value, in which case the user
needs to stop the e-bike for a rest. If the user con-
tinues to run the e-bike, the motor will automati-
cally cut off the power.
