5.1. Cleaning

• Disconnect the numpad from all power sources before cleaning.
• Use a soft, lint-free cloth slightly dampened with water or a mild cleaning solution to wipe the surface.
• For cleaning between keycaps, use compressed air or a small brush.
• Avoid using harsh chemicals, abrasives, or solvents that may damage the finish or keycap legends.

5.2. Battery Care

• To prolong battery life, avoid fully discharging the numpad frequently.
• Store the numpad in a cool, dry place when not in use for extended periods.
• The numpad features smart power-saving, auto light-off, and instant wake-up with a key press to conserve battery.

6. Troubleshooting

6.1. Connectivity Issues

• Numpad not responding: Ensure the numpad is charged. Check the connection mode (Wired, 2.4G, BT) and ensure it matches your device's connection.
• 2.4G Wireless not connecting: Ensure the 2.4G dongle is securely plugged into a USB port. Try a different USB port. Ensure the numpad is set to 2.4G mode.
• Bluetooth not pairing: Ensure the numpad is in Bluetooth pairing mode (BT indicator blinking). Remove previous pairings from your device and try pairing again. Ensure your device's Bluetooth is enabled.

6.2. Lighting Issues

• RGB lights not working: Check if the numpad is powered on. Ensure the brightness is not set to minimum. Use the multifunction knob or software to adjust lighting.

6.3. Key Functionality Issues

• Keys not registering: If a specific key is not working, try hot-swapping the switch with a known working one to determine if the issue is with the switch or the socket.
• Incorrect key output: If you have installed the driver software, check your key assignments and macros to ensure they are configured correctly.
