any button is pressed. The illumination will be turned off again after a period of inactivity.

There are two LEDs on the front: The alarm LED marked with the symbol. The “write enable”
LED marked with the symbol.
The four LEDs placed next to the upper terminal strip will be described later.
6.3 Buttons
There are seven buttons: 4 arrow buttons which will be called UP, DOWN, RIGHT and LEFT. The
menus in the Corrigo E are organized in a horizontal tree structure. The UP / DOWN-buttons are
used to move between menus at the present menu level. The RIGHT / LEFT buttons are used to
move between menu levels. When changing parameters the UP / DOWN buttons are used to
increase / decrease the value of the parameter and the RIGHT / LEFT buttons to move between
digits within the parameter.
• The OK button is used to confirm the choice of a parameter setting.
• The C button is used to abort an initiated parameter change and restore the original value.
