Charging the FTD
The product contains a rechargeable battery. Upon connecting it to a computer via a micro-USB cable, it will automatically begin
charging; even if the ON/OFF switch is on the OFF position (this behavior is similar to the one of mobile phones). The product
can still be used while it’s charging.
During the charging process, the charge state indicator is steady
red
. When charging is completed, the charge state indicator
becomes steady
green
