- Storage: Keep the devices away from extreme temperatures, direct sunlight, and liquids.
7. Troubleshooting
- Q: The keyboard or mouse is not connecting.
- A: Ensure both devices are powered on and fully charged. For 2.4G, check if the USB receiver is properly inserted and the keyboard is in 2.4G mode. For Bluetooth, ensure your device's Bluetooth is enabled, the correct BT channel (BT1/BT2) is selected on the keyboard, and the devices are in pairing mode if connecting for the first time. Try re-pairing if issues persist.
- Q: The backlight is not working or is dim.
- A: Press Fn + Shift to adjust the brightness levels. Ensure the keyboard has sufficient battery charge, as backlighting consumes more power. The backlight can be turned off to save battery.
- Q: The keyboard or mouse frequently disconnects.
- A: This could be due to low battery. Recharge both devices. Ensure there are no strong wireless interferences nearby (e.g., other 2.4GHz devices, Wi-Fi routers). Try moving closer to the connected device.
- Q: The mouse cursor is erratic or unresponsive.
- A: Check the mouse battery level. Ensure the mouse sensor is clean and free from obstructions. Try using the mouse on a different surface.
- Q: Is the keyboard Bluetooth only?
- A: No, the keyboard supports both 2.4G wireless connection via a USB receiver and Bluetooth 5.0/3.0 connections (BT1 and BT2).
- Q: Do both the keyboard and mouse support Bluetooth?
- A: Yes, both the keyboard and mouse support Bluetooth connectivity, in addition to the 2.4G USB connection.
