the fixing screws M3*12 temporarily.

Temporarily install the control unit: Openthe clamp of the control unit, then place
the clamp with rubber sleeve on the suitable position. Adjust the angle of the control
unit to make it easier to operate.
(Note: The diameter of the control unit isØ22.2mm.)Fix the HMI: Adjust the angle of the HMI
to make it easier to see the screen whencycling, then tighten the screws. [Tightening Torque: 1 N.m]

Adjust the installation angle of the HMI:
Loosen the angle adjustment screws. After
adjusting the angle of the HMI to make iteasier to see the screen when cycling, thentighten the screws with an M3 hex wrench.

7.9 ERROR CODE DEFINITION
The ebike system's parts are automatically monitored in real time. If a part is abnormal, the corresponding
error code is displayed on the HMI. The display flashes the code at a frequency of 1 Hz.

The troubleshooting methods in the list are listed in order according to the fault
probability and the operability of the related parts. In practice, dealers can adjust theorder based on the existing tools and spare parts. (For detailed disassembly steps,
please refer to the dealer manual of the corresponding parts on the official website.
<www.bafang-e.com>)
In order to protect the electric parts, before disassembling the parts, please switch off the system
power first by pressing the control unit of HMI and then disconnect the power cable of the disassembled part. Wheninstalling the parts, please fix the parts first, then connect the power cable of the parts, and finnally switch on the system power bypressing the control unit of HMI.
Please contact Bafang after-sale service personnel <service@bafang-e.com> if the above troubleshooting fails to solve theproblem or the error code is not in the above list.
See Appendix A for the detailed error code list.
