When the charge level is low, connect the USB charger using the charging cable provided to the connector located on the D-AIR STREET

Figure 17: Illustration of charger with USB connector
If a 100-240V 50-60Hz current socket is not available, the battery can be charged by connecting the USB cable directly to a personal
computer.
Once the USB cable is connected to the charging source, charging is indicated by the user interface by flashing of the LED at the
frequency of two flashes per second.
The LED will initially be red to indicate that the system needs charging.
When sufficient charge has been reached (around 90%), the LED will turn green.
When the System is completely charged, the LED will begin flashing blue.
