9. Troubleshooting
- Mouse not responding:
Ensure the USB cable is securely plugged into a working USB port. Try a different USB port or computer to rule out port or system issues. - DPI not changing:
Press the DPI button firmly. Ensure you are cycling through the 5 available DPI settings. - RGB lighting not working or behaving unexpectedly:
Check if the RGB backlight sensor is enabled (default setting). If so, the light will turn off when held. Disable the sensor by holding the left and right buttons simultaneously until a white light flashes twice. Cycle through lighting effects by pressing the scroll wheel and back/forward button simultaneously. - Thumb wheel not scrolling horizontally:
Remember that the thumb wheel's horizontal scrolling function is not supported in Office software or on Mac OS. Ensure you are using it in a compatible application and operating system. - Compatibility issues with Mac OS:
While the mouse is compatible with Mac OS for basic functions, the forward and backward buttons, as well as the thumb wheel's horizontal scrolling, are not available. The customization software is also Windows-only.
