consumption significantly. When the application does not require a fast

counted and the output signals will be generated in the normal way.
The following can be selected:
Fast - 1 sec - 3 sec - 15 sec - 30 sec - off.

selected, the display will be switched off after 30 seconds and will be
switched on as soon as a button has been pressed.
