Control Panel - Bosch Compress 3400iAWS E Operation Manual

If the display lighting is off, only the lighting goes on when the selector is
pressed for the first time. When the selector is turned and another
control element is pressed at the same time, the lighting is switched on
in addition to the effect described. The descriptions of the steps to be
carried out by the operator in these instructions always assume that the
lighting is activated. If no control element is actuated, the lighting turns
off automatically (after approx. 30 s with the standard display, after
approx. 30 min in the menu, after 24 h in the event of a fault).
