Note

1.The keyboard and mouse share only one USB receiver to reduce the number of USB ports, which is located in the bottom of the mouse. (Only when the receiver is plugged in, the lights of the keyboard and mouse will light up)

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/mouse before shipment to ensure transportation safety)

3. No software installation is required before the first use, just plug the USB receiver into the USB port, turn the switch at the bottom of the keyboard to the ON position, and turn the switch on the bottom of the mouse to the ON (no light) or LED (with light) position.

4. There will be a little delay or the lights will not turn on when the keyboard/mouse battery is too low, please charge the keyboard/mouse in time, the charging indicator will go off after full charge.

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. Due to the different currents of different computer USB charging ports, some users may need longer charging time to fully charge.

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/mouse is not working, they may lose connection with the USB receiver. Please try pairing with the USB receiver again.
