Operating states
The operating states of the mobile client differ in terms of switch-on response and operation
due to the technical features of the devices.
● Due to the heat generated by its components, the non-artic HMI device can can be
operated briefly until the "TEMP" LED flashes. This corresponds to an exterior
temperature of approx. –10 °C.
● The integrated heating system in the Arctic HMI device allows it to be switched on and
operated even at temperatures below 0 °C if the temperature inside the HMI device
allows it.
● The self-heating of its components and its internal heating mean the Arctic HMI device
can be operated or kept ready to operate until the "TEMP" LED flashes. The lowest
permitted ambient temperature in operation is equal to the minimum storage temperature
of –25 °C.
