Battery/charging
In order to protect the battery in the device, the user should switch off the converter after use. In battery operation,
the K-114 BT switches off automatically after communication has been inactive for 30 minutes.
The battery can be charged via the USB interface. Care must be taken to ensure that the battery can be charged
both via a normal USB port and a DCP (dedicated charging port) or USB adapter. This has the benefit that instead
of being charged with 500 mA or 100 mA (USB port), the battery can be charged with up to 1 A (DCP), reducing
the charging time.
