Note:
1. The USB receiver of the keyboard is located in the groove on the bottom of the keyboard.
2. Please fully charge it before the first use, otherwise it will not last as long as expected when it is not fully charged. (Because we didn't fully charge the keyboard before shipment to ensure transportation safety)
3. Before using the keyboard, plug the USB receiver into the USB port and turn the switch to the ON position.
4. There will be a little delay or the lights will not turn on when the keyboard battery is too low, please charge the keyboard in time.
5. To protect battery life, please use a lower than DC:5V adapter to charge, preferably using the computer's USB port to charge directly.
6. Turning off the keyboard light can extend the battery life of the keyboard moderately.
7. If you can't press "WASD" or "↑↓←→", don't worry, please check if the FN function key is enabled. FN+ "W" key can be used to switch between letter "WASD" keys and arrow "↑↓←→" keys at will.
8.If the keyboard is not working, they may lose connection with the USB receiver. Please try pairing with the USB receiver again. Press ESC +K key, then plug the receiver into the computer.
