How to use
Connect the mouse to an available USB Type-A port on your computer. Place the mouse on a flat, non-reflective surface for best optical sensor performance. Use the left and right buttons for standard selection and context actions, and operate the scroll wheel to navigate documents and web pages. The device requires no additional drivers on most modern operating systems and is ready to use immediately after connection.
Usage recommendations
For consistent tracking, keep the sensor area free of dust and use a mouse pad or matte surface. If pointer speed needs adjustment, change the cursor sensitivity in the operating system settings rather than attempting to modify hardware settings. Disconnect the cable by pulling the connector, not the cord, to avoid damage.
