Setting principle
Settings that cannot be made directly with the operating elements are made through
programming. For this purpose, the individual settings are structured in the form of
menus and operating lines, thus creating practical groups of settings.
The following example shows how to set the time of day and the date.
Example “Setting the time of day“
• Press the ESC button to go one step back at a time, readjusted values are not
adopted
• If no setting is made for 8 minutes (2 minutes with RF devices), the unit will
automatically return to the basic display
• Certain operating lines may be hidden at certain times, depending on the type of unit
and the operating level
