(4) What should I do if some keys are not working or typing automatically?
1. Check if the keyboard battery is low; if so, recharge it.
2. Ensure the keyboard mode matches the connected device system: Fn + W for Windows, Fn + Q for Android, Fn + E for Mac. Check if the Windows key is locked by pressing Fn + Win to unlock. Refer to the manual or function card for details.
3. If only individual keys are not working, clean dust or try replacing with spare switches.
4. If the entire keyboard is not working, check the connection or try another port. For multi-mode keyboards, make sure the connection mode is correctly selected.
5. If none of the above works, long press Fn + Esc for 5 seconds to restore factory settings.
(5) How to reduce power consumption and charge properly?
For long-term use in wireless mode, lower the backlight brightness or turn off all lights to save battery. It’s recommended to use the keyboard’s original cable to connect to a computer for charging while in use.
Important: Do not use any fast-charging devices, as this may cause irreversible damage to the keyboard.
