VOLTCRAFT VC731 Bedienungsanleitung Seite 50

The navigation joystick (5) is used to control the displays/menus. A movement of the
joystick up, down, to the left and right corresponds to a corresponding control movement in
the displays/menus.
If the navigation joystick is pushed like a conventional button, this corresponds to
confirmation of a setting or selection ("ENTER").
If the current clamp is switched on the white LED (11) will be automatically activated when
the opening lever of the current clamp is operated and will be deactivated when it is
closed. As an example, the lamp makes it easier to place correctly the current clamp
sensor in a dark distribution cabinet.
The background lighting of the LC display switches automatically off after roughly 15
seconds to save electricity. If you move/operate the adjustment wheel (7) or the navigation
joystick (5), then the background lighting is activated once again for 15 seconds.
