6.3 Status indicator (LED)
The status indicator (LED) is located next to the USB port on the reading
device and has different functions.
If the reading device is connected to the charger or a PC via a USB cable,
the LED lights up red to indicate charging of the lithium ion battery. If it lights
up green, the storage battery is fully charged and the device can be
disconnected from the PC or charger.
In addition to this charging indicator, the LED signals successful or failed
measurements as sometimes a direct view of the display is not possible.
If the LED flashes green after a measurement, the measurement was
successful. If it flashes red, an error has occurred.
