Switching the internal light (Only on MIDI KG/FG products)

As default setting the cabinet controller is delivered turned off.

when turning the controller off (Setting r12 to 0).
Push the upper button and keep it pushed during normal operation until the
display does show r01.
Push the upper or the lower button until r12 is displayed.
Push the center button.
Push the lower or the upper button in order to switch between the settings 0
and 1 (-1 is only for service).
o Setting 0 means the cabinet is OFF.
o Setting 1 means the cabinet is ON.
Confirm the new setting by pushing the center button.
In order to skip the r01 parameter, the controller does only need to be left
untouched for approx. 30 seconds. This will make the controller fall back to the
normal operation mode, meaning that the cabinet will either be in oFF – mode
or be running.
