How to use

Plug the USB connector into an available USB port on your computer or laptop; the system should recognize the mouse automatically and enable immediate use without additional drivers in most environments. Adjust the DPI control according to your preference for pointer speed—lower DPI for precision tasks and higher DPI for faster cursor movement. Maintain a clean surface for optimal optical tracking and position your hand so that the wrist rests naturally on the desk to reduce fatigue.

Usage recommendations

For best performance, use on a flat, non-reflective surface or a mouse pad. Periodically wipe the optical sensor area and the mouse feet with a soft, dry cloth to remove dust. If using on a laptop, ensure the USB port is securely connected and avoid bending the cable sharply to preserve longevity.
