In order to facilitate the setting of the parameters the buttons are equipped with an "AUTOSCROLL" function
while the controller is in the configuration mode. It permits the user to rapidly advance to the next setting and
configuration screens, the digits, or the cursor position. The "AUTOSCROLL" function will only be enabled
when the user presses and holds the corresponding buttons.
