To properly recharge the device, simply place it on its base (plugged in and powered) and check that the Aerator is properly connected to its base. If it is correctly installed, then a battery-shaped charging logo will appear at the top right of the screen. As long as the indicator is active, it means that the Aerator is charging. If the screen is off, there is a good chance that the aerator is not properly connected. Click here to see how the aerator should be connected.
