Troubleshooting
- Keyboard not connecting/pairing: Ensure the keyboard is charged and powered on. Make sure Bluetooth is enabled on your device and the keyboard is in pairing mode. If your PC does not have built-in Bluetooth, a separate Bluetooth adapter (version 4.0 or higher recommended) is required.
- Lag or delayed response: While generally responsive, ensure there are no major obstructions between the keyboard and your device. If using a Bluetooth adapter, ensure it is a reliable version (e.g., Bluetooth 4.0 or higher).
- Backlight not working: Check if the backlight is turned on using the dedicated backlight key. Ensure the keyboard has sufficient battery charge.
- Multimedia keys not functioning correctly: Remember to press the Fn key in combination with the desired function key. Some functions (Screenshot, Input Language switching, Soft keyboard) are specific to iOS systems. There is no dedicated lock button to make function keys default without pressing Fn.
- Keyboard stops working after a short period: This could indicate a low battery. Recharge the keyboard fully. If the issue persists after charging, contact customer support.
- No Print Screen key: This keyboard does not have a dedicated Print Screen key. For Windows, you can use the Snipping Tool or other screenshot utilities. For iOS, use the Fn+F4 shortcut.
User Tips
- Gaming Performance: Users have reported that the keyboard performs well for gaming, with no noticeable input delay.
- PC Connectivity: If your PC lacks built-in Bluetooth, a Bluetooth 4.0 adapter (such as a Baseus 4.0 adapter) has been noted to work effectively without significant delay.
- Battery Management: While the keyboard offers up to 70 hours of use with the backlight off, frequent use of the rainbow LED backlight will reduce battery life. Consider turning off the backlight when not needed to extend usage time between charges.
- Tablet Compatibility: The keyboard has been successfully connected to various tablets, including Huawei MatePad and Samsung Android tablets.
Maintenance
- Clean the keyboard regularly with a soft, dry, lint-free cloth.
- For stubborn dirt, lightly dampen the cloth with water or a mild cleaning solution, ensuring no liquid enters the keyboard.
- Avoid using harsh chemicals, abrasives, or solvents.
- Store the keyboard in its carrying case when not in use to protect it from dust and scratches.
