Installation method
Open the locking clamp of the display, put it on the left handlebar (standard handle pipe specification: φ 22.2), adjust it to an easy-to-operate position, and fix and tighten the fixing screw with M3 hexagon socket. Locking torque: 0.8N.m * Display damage caused by excessive torque is not covered by warranty.
Connect the display connector 5pin plug-in to the controller docking connector as indicated.
display interface
boot display
Turn on the LED green light to make the marquee effect of 0.1s, and then fully display the colors. Switch each color to blink twice.
Normal riding state
Gear indication: gear 0 (white light), gear 1 (green light), gear 2 (blue light) and gear 3 (red light)

functional operation
On/Off:
Keep the normal connection state between the display and the controller, press the
key for 2 seconds when the display is turned off, and the display will fully display the startup interface, then enter the basic interface normally and start working; Long press the
(2 seconds) in the power-on state, and the display will turn off. If the rider does not operate the meter for 5 minutes (default) (and the speed is 0), the meter will automatically turn off.
Power shift switch:
Press the
key or the
key to switch the power-assisted gear and change the power-assisted mode. There are four modes: 0/ low/medium/high gear.
Help implement
Press the
key for 2 seconds, and then enter the state of boosting implementation. Release the
key, that is, quit boosting.
Implementation mode.
Headlights on (brightness switching)
Press the long 
key, and after 1 second, the headlights turn on (need the support of the controller), and the brightness of the LED lights decreases. Press the long
key again, and after 1 second, the headlights turn off, and the display brightness recovers.
Power display
When the battery charge is normal, the 5-segment LCD of the battery displays the charge according to the time and the outer frame lights up. When the battery runs out of power, the 5-segment LCD of the battery completely goes out and the outer frame flashes, so it needs to be charged immediately. The battery charge is shown in the following figure:
Battery charge (C) displays the corresponding table (the charge indication can be adjusted according to the demand)

Fault display
The fault code is displayed, and the fault icon prompts (the red LED flashes, and the numerical code follows the 5-digit binary plan).
The red flashing of the above four LED lights indicates that the display communication is poor with error30 (binary 11110 is equal to 30 after conversion)
Definition of fault code
The fault code is obtained from the controller instruction. Generally, the controller defines the meaning of the error code. The meter only defines the unreachable ERROR 30.
Fault code | Fault description | Investigation and analysis |
E30 | Communication failure, the display can't receive the data from the controller or the received data is wrong data. | 1: Check whether the TX and RX communication lines are connected correctly. 2. Check whether the harness and connectors are loose or broken. 3. Check whether the display communication protocols match. |
Connection definition
The outlet terminal of the display is connected with the terminal of the controller.

Note: The leads of some products are waterproof plug-ins, so users can't see the color of the leads in the harness.
Matters needing attention
During use, pay attention to safety, and don't plug and unplug the display when it is powered on.
Try to avoid using it in harsh environment, such as heavy rain, heavy snow and exposure.
When the display cannot be used normally, it should be sent for repair as soon as possible.
