6. Maintenance

6.1 Cleaning

To clean your keyboard, first disconnect it from your device. Use a soft brush or compressed air to remove dust and debris from between the keycaps. For stubborn dirt, gently wipe the keycaps and case with a slightly damp, lint-free cloth. Avoid using harsh chemicals or abrasive materials.

6.2 Battery Care

To prolong battery life, avoid fully discharging the keyboard frequently. Charge it when the battery indicator on the TFT screen shows low power. If storing the keyboard for an extended period, charge it to about 50% and store in a cool, dry place.

7. Troubleshooting

• Keyboard not responding: Ensure the keyboard is charged. Check the connection mode (wired, 2.4GHz, Bluetooth) and ensure it matches your device's connection. Try reconnecting the cable or re-pairing Bluetooth.
• 2.4GHz/Bluetooth connection unstable: Ensure the keyboard is within range of the receiver/device. Avoid interference from other wireless devices. Try moving the receiver to a different USB port.
• Keys not registering: If specific keys are not working, ensure the switches are properly seated in their sockets. For hot-swappable switches, try reseating or replacing the switch.
• TFT screen not displaying: Ensure the keyboard is powered on. If the issue persists, try resetting the keyboard (refer to software or manufacturer's website for specific reset instructions).
• RGB lighting issues: Check lighting settings via the TFT screen or the programmable software. Ensure the brightness is not set to zero.
