The backlight lamp is managed by the Gen-set control module, which switches off the backlight after a
programmable time (P.492) if no buttons are pressed in the meantime. Press any button to switch the
lamp ON again, (we recommend using the SHIFT button as it has no function when used alone).
This function can be disabled by setting parameter P.492 to 0.
The Brightness can be adjusted by pressing the SHIFT + LEFT buttons to decrease the
Backlight or the SHIFT +RIGHT buttons to increase it.
