Recommendations

For best tracking and long skate life, use the mouse on a clean, flat surface or a mouse pad. Remove the USB receiver from the computer when transporting the mouse and store it in the dedicated compartment. Replace batteries with the same type (AAA) and follow local recycling guidelines for electronic waste and packaging.
