How to use

Insert the wireless receiver into a compatible USB port on your computer and switch the mouse on if it has a power control.

Adjust the DPI setting using the dedicated sensitivity control or software if available to match your preferred pointer speed. Place the mouse on a flat surface or mouse pad and use it normally for clicking, dragging, and scrolling.

Usage recommendations

For consistent tracking, use the Marvo G803 on a plain, non-reflective surface or a quality mouse pad.

Adjust DPI to a lower value for precise tasks and a higher value for fast cursor movement.
