The menu displays have lists of items for selection. The UP or DOWN function keys move the cursor (>)
through the menu list. After moving the cursor to the desired item, press ENTER. If the item exists in the
ROC configuration, a new display for the selected item appears. This display may be another menu or an
information display. If the item does not exist, the cursor moves to the start of the menu display list.
