7. Troubleshooting

If you encounter issues with your TISHLED F20 Numpad, refer to the following common solutions.

Problem	Possible Cause	Solution
Numpad is not recognized by the computer.	Loose USB connection, faulty USB port, or incompatible adapter.	Ensure the USB cable is securely connected to both the numpad and the computer. Try plugging the numpad into a different USB port on your computer. If using a USB-C adapter, ensure it is functional and compatible. Restart your computer.
Keys are not responding or input is incorrect.	Software conflict, debris under keycap, or hardware issue.	Ensure no other software is interfering with keyboard input. Gently remove the keycap and check for any debris that might be obstructing the switch. Test the numpad on another computer to rule out system-specific issues.
Backlight is not working or cannot be controlled.	Incorrect backlight settings or power issue.	Ensure the brightness is not set to the lowest (off) setting. Press Calculator + 8 to increase brightness. Verify the numpad is receiving power (check USB connection).
Repeated input for a single key press (e.g., '1' key).	Switch debounce issue or debris.	Gently remove the keycap and inspect the switch for any visible issues or debris. Ensure the key is fully releasing after each press. Test on another computer to determine if the issue is with the numpad or the host system.
