The submenus accessed for each circuit are identical but the content of each of them reflects the status of the
corresponding circuit. In the following the submenus will be explained only once. If only one circuit is available
the item Circuit #2 in the above table will be hidden and not accessible.
Each of the above links will jump to the following submenu:
