3.2.1 The MENU Control Key
Press the MENU key to enable the menu system. The menu system can be used with-
out interrupting ongoing changer operations. If the Top Menu is not displayed, press-
ing the MENU key at any time always returns control to the Top Menu (Figure 3-3).
If the Top Menu is displayed, press the MENU key to exit the menu system and re-
turn to the Operating Display.
3.2.2 The (UP) and (DOWN) Control Keys
•
While navigating through the menu system, the (UP) and (DOWN) keys
move the item pointer (right-pointing arrow) up and down the left column
of the display. The display automatically scrolls when necessary. The
pointer identifies the current selection, as shown in Section 3.2.3 below.
• If a value is highlighted, the (UP) and (DOWN) keys change the value
of the highlighted character or word. The DOWN key changes the charac-
ter to the preceding character in the sequence (i.e., from B to A, or from 2
to 1). Pressing the (UP) key has the opposite effect.
• If a multiple choice value is highlighted, the (UP) and (DOWN) keys
cycle through the available choices.
• If the (UP) or (DOWN) key is pressed and held down, the control key's
action repeats at a rapid rate.
