It is important that you fully charge ICON before you use it for the first time. A normal charge will take 3-5 hours although it may take longer when charging for the first time.
Remove rear adapter, insert the supplied micro USB cable and connect to a charging source such as a laptop or a phone charger.
An amber light indicates that the light is charging. When the light goes out, ICON is fully charged. It is not possible to operate ICON while charging.
