How to use

Connect the mouse to an available USB port on your computer; the system should recognize it automatically without additional drivers in most modern operating systems. Place the mouse on a flat, stable surface or use a mouse pad for improved tracking. Adjust pointer speed and button settings in your operating system’s mouse settings if necessary to match your preferred sensitivity and scrolling behavior. For left- or right-hand users, the symmetrical shape allows comfortable positioning of the hand and fingers.

Usage recommendations

For consistent performance, keep the optical sensor area free of dust and debris; periodically wipe the underside with a soft, dry cloth. Use on a non-reflective surface to maintain accurate tracking. If you require higher sensitivity for specific tasks, change pointer speed in software rather than modifying physical hardware. Store the cable without sharp bends to extend its service life.
