How to use
Connect the mouse to an available USB Type-A port on your computer and allow the operating system to install any generic drivers automatically. Position the mouse on a stable surface or mouse pad and use the left and right buttons for selection and context actions; use the middle button/scroll wheel for scrolling through documents and webpages. The 800 DPI sensitivity is set for standard cursor speed; adjust system-level pointer settings if you require faster or slower movement.
Usage recommendations
For best tracking performance, use the mouse on a clean, non-reflective surface or a fabric mouse pad. Avoid very glossy or glass surfaces which can reduce optical accuracy. Regularly wipe the mouse feet and sensor area to prevent dust buildup. If you need finer pointer control, change the pointer speed in your operating system settings rather than modifying physical setup.
