6. Recharging
When the battery is low, indicator will flash in red. If all indicators are off, it means the battery is completely
drained. Under both situations, the keyboard should be recharged. The required voltage for charging is
5V with current under 250mA. A current control chip is set inside the keyboard for overcurrent protection.
You can recharge the keyboard by using an ordinary phone charger or on the USB port of a computer that
regularly outputs voltage at 5V. The keyboard can be fully recharged in approximately 3-4 hours. Indicator
keeps red when the keyboard is being recharged. The battery indicator will turn green when the keyboard
is fully recharged.

You can use the keyboard while it is being recharged.
7. Sleeping mode
The keyboard will sleep automatically if there is no operation on it for 30 minutes. Wake it up by pressing
any button. Under sleep mode, Bluetooth will disconnect automatically, and you can build reconnection
