5.4 Notes on the built-in storage battery
- The correct storage battery level (SoC = state of charge) is only displayed after the first full charge to 100 %.
The SoC remains at 0 % until full charging has been completed.
- As soon as the storage battery has been discharged to 0 %, the storage battery will initially charge slowly (approx. 30 minutes).
Then, the actual charging takes place with a higher current.
- If the storage battery is exhausted and the power supply from the mains is missing, the device switches off automatically.
It is recommended to always switch off the device via the ON/OFF switch after use.
