A prerequisite for this is that the backgroundlighting is switched off and that no peripheral devices are connected.The device automatically switches to battery operation as soon as the mains supplyis interrupted. When the mains supply is restored, the device automatically switchesback to mains operation.The battery symbol indicates the present charging level of the battery. 1 segment cor-responds to approx. 25 % capacity.
