5. Troubleshooting
If you encounter issues with your Chilkey ND75 keyboard, please refer to the following common solutions:
- Keyboard Not Responding:
- Ensure the keyboard is fully charged or connected via USB-C.
- Check the connection mode (wired, 2.4GHz, Bluetooth) and ensure it matches your device's connection. Use Fn key combinations to switch modes.
- For 2.4GHz, ensure the dongle is securely plugged into a working USB port.
- For Bluetooth, ensure Bluetooth is enabled on your device and the keyboard is paired. Try re-pairing if necessary.
- Verify the wireless switch under the Right Shift Keycap is in the correct position (ON for wireless modes).
- RGB Lighting Issues:
- Check the keyboard's LCD screen settings for brightness and effect controls.
- Ensure the keyboard's battery has sufficient charge, as low power can affect lighting.
- If using custom software, ensure it is up-to-date and correctly configured.
- Keys Not Registering / Mushy Feel:
- Due to the hot-swappable design, switches can sometimes come loose when removing keycaps. Gently press down on the affected switch to ensure it is fully seated in the PCB.
- If a switch feels mushy or is not registering, consider replacing the individual switch. The hot-swappable feature makes this easy.
- Software/Driver Issues:
- The keyboard has independent driver/software for advanced customization. If you experience issues, ensure you have the latest version installed from the official Chilkey support website.
- Some users have noted the software can be clunky; ensure your operating system is compatible and try reinstalling the software if problems persist.
If these steps do not resolve your issue, please contact Chilkey customer support.
