- On your computer, go to Bluetooth settings and search for new devices.
- Select the DELUX M900 mouse from the list of available devices to pair.

5. Operating Instructions
5.1. DPI Adjustment
The mouse features a dedicated DPI button (refer to the product diagram in Section 4.3) to cycle through preset DPI levels. You can customize these levels using the web-based driver.
5.2. Web-Based Driver Customization
The DELUX M900 Pro+, M900 Ultra V2, and some M900 Pro V2 models support a web-based driver for advanced customization. This allows you to:
- Modify DPI settings and stages.

- Customize button assignments.
No software download is required. Simply access the web driver through your browser to personalize your mouse settings.

5.3. Competitive Mode (M900 Ultra V2)
The M900 Ultra V2 features a 'Competitive Firmware MAX' mode. Activating this mode (typically via a dedicated button or software setting) deeply unleashes the hardware performance of the main control chip and sensor, providing an even smoother control experience. This mode can achieve a stable 20000 FPS.

5.4. Charging
Connect the mouse via the USB-C cable to charge. The mouse supports fast charging, providing approximately 6 hours of usage from just 3 minutes of charging.

6. Maintenance
6.1. Cleaning
To maintain the performance and appearance of your mouse:
- Wipe the mouse surface with a soft, dry cloth.
- Avoid using harsh chemicals or abrasive materials, especially on the ice-feel competitive coating.
- Ensure the optical sensor on the bottom is free from dust and debris for accurate tracking.
6.2. PTFE Feet
The PTFE feet provide a smooth glide. Keep them clean and free from dirt. If the glide performance degrades over time, replacement PTFE feet may be available from DELUX.

7. Troubleshooting
7.1. Connection Issues
- Wireless (2.4G/Bluetooth): Ensure the mouse is charged and turned on. Check that the receiver is securely plugged into a USB port or that Bluetooth is enabled and paired correctly on your computer.
- Wired: Verify the USB-C cable is properly connected to both the mouse and the computer.
7.2. Performance Issues (Stuttering, Lag)
If you experience stuttering or lag, especially when using the 8KHz polling rate, your computer's specifications might be a limiting factor. Consider the following recommendations:
Recommended PC Configuration for 8K Polling Rate:
| Component | Intel Platform | AMD Platform |
|---|---|---|
| CPU | i7 9700K or above | Ryzen 7 3700X or above |
| Graphics Card | NVIDIA RTX2060 or above | AMD RX5700XT or above |
| RAM | 16GB or above | 16GB or above |
| Display | 240Hz refresh rate or above | |
If your system does not meet these specifications, it is recommended to lower the polling rate (e.g., to 1KHz) for a smoother experience.

7.3. Double-Click Issues
The M900 Pro+ and M900 Ultra V2 models feature TTC optical micro-switches designed to prevent double-click issues. If you experience this problem with other models, ensure your firmware is up to date via the web driver.
