5. Maintenance
- Cleaning: Use a soft, dry cloth to clean the keyboard surface. For deeper cleaning, a slightly damp cloth can be used, ensuring no liquid enters the keycaps or internal components.
- Battery Care: To prolong battery life, avoid fully discharging the keyboard frequently. Recharge when the low battery indicator appears. If storing for an extended period, charge the keyboard to about 50% and turn it off.
- Storage: Store the keyboard in a cool, dry place away from direct sunlight and extreme temperatures.
6. Troubleshooting
- Keyboard not connecting: Ensure the keyboard is turned on and fully charged. For 2.4G, check if the USB receiver is properly inserted. For Bluetooth, ensure the keyboard is in pairing mode (flashing indicator) and your device's Bluetooth is enabled. Try re-pairing the device.
- Keys not responding or double typing: Ensure the keyboard is fully charged. If the issue persists, try cleaning around the affected keys. Ensure you are pressing keys centrally and firmly.
- Backlight not working: Ensure the keyboard is turned on. Long press the RGB button to toggle the backlight. Check battery level.
- Short battery life: Backlighting consumes more power. Reduce brightness or turn off the backlight to extend battery life. Ensure the keyboard is fully charged before use.
- Lag or delay in input: Ensure the keyboard is within range of the receiver/device. Avoid interference from other wireless devices. For 2.4G, try plugging the USB receiver into a different USB port, preferably a rear port on desktop PCs.
