4. Maintenance
To ensure the longevity and optimal performance of your Dareu EK87PRO keyboard, follow these maintenance guidelines:

- Cleaning the Keyboard Body: Use a soft, dry cloth to wipe the keyboard body. For stubborn dirt, a slightly damp cloth can be used, but avoid excessive moisture.
- Dust Removal: Use compressed air to remove dust and debris from between the keycaps and switches.
- Switch Maintenance: If you frequently hot-swap switches, ensure the switch sockets are clean and free of debris to prevent connection issues.
- Storage: When not in use for extended periods, store the keyboard in a dry, dust-free environment.
5. Troubleshooting
If you encounter issues with your EK87PRO keyboard, try the following solutions:
- Keyboard not responding:
- Check the connection mode switch (Wired, 2.4G, BT) and ensure it matches your connection method.
- For wired mode, try a different USB port or cable.
- For 2.4G wireless, ensure the receiver is securely plugged in and try a different USB port.
- For Bluetooth, ensure Bluetooth is enabled on your device and the keyboard is paired. Try re-pairing if necessary.
- Check the battery level. If low, connect the keyboard to a power source for charging.
- Keys not registering or double-clicking:
- This keyboard features an E-race low latency chip and adaptive anti-shake technology to reduce double-clicks. If issues persist, try cleaning the affected switch or replacing it with a new one (due to hot-swappable design).
- Ensure the switch is fully seated in its socket.
- RGB lighting not working:
- Check if the lighting is turned off or set to a very low brightness. Use the Fn key combinations to adjust.
- Ensure the keyboard has sufficient power, especially in wireless modes.
- Intermittent wireless connection:
- Ensure the keyboard is within range of the receiver (2.4G) or paired device (Bluetooth).
- Avoid sources of interference (e.g., other wireless devices, large metal objects).
- Try updating your device's Bluetooth drivers.
