How to use

Recommendations

For stable wireless performance, keep the USB receiver within a few metres of the mouse and avoid placing large metal obstacles between the receiver and the mouse. Clean the optical sensor area and mouse feet periodically to maintain smooth tracking. If configuring extra buttons, use your operating system’s mouse settings or available utility software to assign functions that match your workflow.
