Product Overview
Built around the J900 RGB Lighting Programmable Gaming Mouse layout and controls, this JYSJ J900 user guide explains how to get the mouse working quickly and then customize it for games. This guide is based strictly on the official JYSJ documentation for the J900 RGB Lighting Programmable Gaming Mouse.
The mouse uses a wired USB connection for plug-and-play operation, with six buttons you can program through the included macro driver workflow. It also supports six DPI levels up to 6400 DPI and six RGB lighting modes, including an option to turn lighting off when you want fewer distractions.
If you are setting up a new gaming PC or replacing a basic office mouse, the J900 is positioned for users who want adjustable sensitivity and programmable inputs without needing complex hardware installation.
Best suited for:
- Players who want quick sensitivity changes using the DPI loop controls, including up to 6400 DPI.
- Users who need multiple programmable buttons for in-game actions or shortcuts.
- Setups where wired USB plug-and-play is preferred for straightforward connection.
Consider alternatives if:
- Your computer environment is outside the operating system support listed in the official documentation.
- You cannot accommodate a wired USB mouse with a 150 cm cable in your desk layout.
One easy-to-miss detail in the documentation is that after you save your configuration in the driver, you are expected to start the driver again the next time you use the mouse to keep all customization features available.
How to Use J900 RGB Lighting Programmable Gaming Mouse
To use the J900 mouse, plug it into a USB port and confirm it works as a standard mouse first. Then install the seller-provided macro programming software to customize buttons, DPI stages, and lighting. Finish by applying and saving your configuration so your settings stay consistent when you relaunch the driver later.
Identify the buttons and controls before you customize
The mouse layout includes a standard Left Button and Right Button, a Mid Button, forward and back buttons, plus a DPI loop control labeled DPI Loop +/-. It also includes an RGB control labeled RGB light Mode Switch, which changes lighting patterns and can disable lighting.
JYSJ J900 user guide: DPI and lighting controls
Use DPI Loop +/- to cycle through the default DPI stages of 1000, 1600, 2400, 3200, 4800, and 6400. This lets you quickly match pointer speed to the task, such as slower control for precision aiming or faster movement for general navigation. Use the RGB light Mode Switch to move through up to six lighting patterns or turn the lighting off.
Install and open the macro programming software
Download the macro programming software from the website provided by the seller, then open it directly after download. The documentation indicates you should first confirm the mouse is connected and operating normally, and then open the J900 macro software to access macro programming features.
- Connect the mouse by USB and verify basic movement and clicking work.
- Download the driver from the seller-provided website and open it after download.
- Use the software to customize buttons 1 through 6 with your preferred functions.
- Adjust DPI stages in the software if you want different values beyond the default six-segment setup.
- Select a lighting mode in the software if you prefer software control rather than only using the hardware mode switch.
- Click Applications, then click Save Configuration to store the setup.
- When you use the mouse later, start the driver again so all customizations remain available.
Tip: Before launching a game, confirm your saved profile is active by testing a programmed button and checking that your DPI stage changes as expected.

Troubleshooting
If the J900 mouse is connected but does not behave the way you expect, focus on the driver and control settings first, since most advanced features depend on the macro software and saved configuration.
| Problem | Cause | Solution |
|---|---|---|
| Macros do not run in-game | The macro programming software is not installed, not opened, or the configuration was not saved. | Download the J900 macro software from the seller-provided website, open it after confirming the mouse works normally, then click Applications and Save Configuration. |
| DPI will not change when I try | The DPI stage is not being cycled with the correct control. | Use the mouse control labeled DPI Loop +/- to cycle through DPI stages, and adjust DPI stages in the driver if needed. |
| RGB lighting does not change | The lighting mode is not being switched or lighting is set to off. | Use the control labeled RGB light Mode Switch to cycle lighting patterns, or set a lighting pattern in the driver if you are managing lighting through software. |
Next Steps
After you confirm basic plug-and-play use, install the seller-provided macro driver and create a simple profile with one or two programmed buttons to validate your workflow. Save your configuration and remember to start the driver again during future sessions so your custom settings remain available.
If you need the download link again or have issues beyond the documented setup and configuration steps, contact the seller or manufacturer support channel referenced with your purchase.
How do I adjust pointer precision in the J900 RGB Lighting Programmable Gaming Mouse software?
