If your Rival 600/650 isn't responding on certain surfaces, don't smash your mouse against the wall just yet. Chances are your mouse just needs to be calibrated.
To do this, you'll need to:
- Press and hold the CPI button for several seconds with the mouse flat on the surface (see image below).
- Release the button after the mouse illumination flashes.
- This will calibrate the mouse to the surface you are currently using.
