1.4. Charging the FTD
The device is equipped with a rechargeable battery. Once the device has been connected to a USB charger or the USB socket of a computer, it
will start to charge automatically; even if the ON/OFF communicator is set to OFF (this functions in exactly the same way as a mobile phone).
The device can be used while it is charging. During charging, the charge indicator will be red. When the device is fully charged, the indicator will
turn green.
