4.1 Battery
The batteries serve to supply the device with power in the event of a failure in the external power supply. The
functionality of the device is restricted in battery mode. The device continues to measure and records all data
in the internal memory. The device cannot communicate via the Ethernet interface, but the wireless interface
works normally.
Lithium batteries of the type AA with 3.6 V are used, per section 1.5.1. Make sure they are inserted correctly.
The poles are marked on the battery and in the battery compartment.
