How to use
Connect the keyboard and mouse to available USB ports on your PC or compatible device. Place the keyboard on a stable surface and adjust the mouse position for a comfortable grip. The devices are plug-and-play—no additional drivers are typically required for basic functionality. Use the number pad and dedicated Microsoft Copilot key on the keyboard for faster access to numeric input and supported Copilot features. Adjust pointer speed in your operating system settings if necessary to match the 1600 DPI sensitivity.
Usage recommendations
For reliable performance, keep the USB connectors clean and avoid exposing the keyboard to prolonged direct sunlight. In case of spills, disconnect the keyboard immediately and allow it to dry; the waterproof membrane offers spill resistance but is not a substitute for extended water exposure. Position the mouse to support a natural wrist posture for prolonged comfort.
