Briefly press ”BOOST” button to switch to different data interfaces,then circularly to show single
trip distance (Trip,km) → total distance (ODO,km) → maximum speed (MAX,km/h) → average speed
(AVG,km/h) → remaining distance (RANGE,km) → energy consumption (CALORIES/CAL,KCal) → riding
time (TIME,min) → real-time output power (POWER,w).
• Headlight/Display backlight switch:
Press and hold ”+” to turn on the display backlight as well as headlight, this moment you will see the

ERROR CODE DEFINTION
ERROR CODE DEFINITION
DP C240.CAN display can show e-bike faults. When a fault is detected, the icon will be displayed. One of the
following error codes will be displayed.
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-
