4.3 Driver Installation
For full customization and advanced features, download and install the self-developed Vhub client software. This software is available for both webpage and Windows clients. Visit www.vgnlab.com for driver downloads and additional services.

5. Operating Instructions
5.1 DPI Adjustment
The mouse features a dedicated DPI adjustment button, typically located near the scroll wheel. Press this button to cycle through preset DPI levels. You can customize these levels using the Vhub software.
5.2 Customization with Vhub Software
The Vhub software allows for comprehensive management of your mouse settings, including:
- On-board storage for profiles
- Editable mouse buttons (macro management)
- Precise DPI adjustment and overclocking (up to 36000 DPI for Promax, 42000 DPI for Ultra+)
- Return rate settings (wired/wireless 8k)
- Superb mode and game enhancement settings
- Cool light settings (if applicable)
5.3 Charging the Mouse
The F2 Ultra+ model supports self-developed V-charge 3C fast charging technology. Charging for 1 minute can provide up to 6 hours of use. The F2 Promax model has an 800mAh battery but does not support fast charging.

6. Maintenance
6.1 Cleaning
The mouse features an ice-like skin-like coating that is delicate and non-greasy, making it easy to clean. Use a soft, dry cloth to wipe the surface. Avoid using harsh chemicals or abrasive materials that could damage the coating.
6.2 Encoder and Foot Patches
The mouse is equipped with a TTC dustproof gold encoder, designed for durability and smooth scrolling. The 100% Teflon foot patches ensure smooth glide. If the glide performance degrades, you may replace the foot patches using the provided set.

7. Troubleshooting
7.1 Performance Issues at 8000Hz
If you experience slight lag or inconsistent performance at 8000Hz, ensure your computer meets the recommended system configurations (refer to Section 4.1). A lower system configuration than recommended may affect the mouse's ability to perform optimally at higher polling rates. Adjusting in-game or system inquiry rate settings might also be necessary.
7.2 Battery Life and Charging
The fast charging function (on F2 Ultra+) can accelerate battery aging over time. For daily use and to extend battery service life, it is recommended to charge the mouse by connecting it to your computer's USB interface. During charging, avoid prolonged full charges, excessively high temperatures, or humid environments to ensure charging safety and battery longevity.

8. User Tips
- Grip Styles: The mouse design is suitable for various grip styles including palm grip, claw grip, and fingertip grip, allowing users to find their most comfortable hold for competitive play.
- Firmware Updates: Regularly check the VGN website (www.vgnlab.com) for firmware updates to ensure your mouse has the latest performance enhancements and bug fixes. The F2 Ultra+ version specifically supports 'super god competitive firmware' for maximum performance.
- Lightweight Design: Both models are designed to be lightweight (51g for Ultra+, 55g for Promax) for quick movements and reduced fatigue during long gaming sessions.
