Battery charge (C) display correspondence table (charge indication can be adjusted
according to requirements)
When the battery power is normal, the battery 5-segment LCD displays the power
according to time and the outer frame lights up. When the battery is exhausted, the
5-segment LCD of the battery is completely extinguished and the outer frame flashes, so
it needs to be charged immediately. The battery charge is shown as follows:

Within 10 seconds of starting up, press and hold the (2 seconds), and the system
will enter the user setting interface. In this state, relevant parameters can be set and
viewed.
Long press the (2 seconds) to exit and save the setting status.
When the user sets the interface state, if it is not operated for 10 seconds, the display
will return to the normal riding state without saving the parameter settings.
In the user setting interface state, within the setting items, press / briefly to
switch the setting contents.
After entering the setting interface, press / briefly to switch the setting content
to enter the wheel diameter information (the second section of the gear flashes and the
fifth end is always on). Wheel diameter information can be viewed (700C is used instead
of 7c, 27.5 is used instead of 27).

2.8 fault information
2.8.1 Fault display
The fault icon and fault code are displayed, and the fault code flashes.
2.8.2 Definition of Fault Code
The fault code is obtained from the controller instruction.
Generally, the controller defines the meaning of error
codes. The meter only defines ERROR 30 that cannot
communicate.
Fault code
E30
Fault description
Communication failure, the display can't
receive data from the controller or the
received data is wrong data.
1: Check whether TX and RX
communication lines are connected
correctly.
2: Check whether the harness and
connector are loose or broken.
3. Check whether the display
communication protocol matches
