• Verify that the correct connection mode (2.4G, Bluetooth 1, Bluetooth 2, or Wired) is selected and properly paired/connected according to the instructions in the Setup section.
• For 2.4G mode, ensure the USB dongle is securely plugged into a working USB port on your device. Try a different USB port if necessary.
• For Bluetooth mode, ensure Bluetooth is enabled on your device and the keyboard is in pairing mode (blue light flashing). Try unpairing and re-pairing the keyboard.
• Ensure the keyboard battery is charged. Connect it to a power source.
• Try restarting the keyboard and your connected device.

Cursor not moving or erratic:

• Check the trackball for any obstructions, dust, or dirt. Gently clean the trackball and its housing.
• Adjust the CPI value using Fn + F1-F4 to see if a different sensitivity setting improves performance.
• Ensure the keyboard is within the working distance (7-10m) of your device for wireless connections.

Backlight not working or dim:
