Tracking randomly stops, and sometimes the mouse disconnects and LED turns OFF. I have to reconnect the mouse. How can I fix this problem?

Please test the unit on another PC and/or USB-port and follow these troubleshooting steps.

1. Reinstall the mouse driver

2. Clean the sensor lens with a brush.

3. Test the mouse on a different LOD setting. (For EC-A, FK, ZA,  EC-C, FK-C, ZA-C, S-C, EC-CW seires)

To learn more about How do you change/reset the LOD (Lift Off Distance) setting of the mouse?

If the problem persists and the product is still within the warranty period, please contact our support team.
