Think of the menu choices as a vertical list in the display which moves up
or down each time an arrow button is pressed. This list or menu is viewed
through a window, the menu choice window, in the display (see figure 2).
The menu choice window is the lower 2 or 3 lines of the display. Pushing
the arrow buttons brings another portion of the menu into menu choice
window. This is referred to as scrolling through the menu (see figure 3).

An asterisk, “*”, will always be displayed in the far left position of the top
line in the menu choice window. As the menu is scrolled through,
different choices appear next to the “*”. The “*” in the display
corresponds with the

Q

button. Pushing the

Q

button selects the menu

choice which is adjacent to the “*” in the menu choice window.

As described previously, the

OFF

button allows an exit or escape from

the current menu and a return to the previous menu. This allows a rapid
exit from an inner menu to the

TESTING MENU

by repeatedly pushing

the

OFF

button. Pushing

OFF

while in the

TESTING MENU

will turn

the colorimeter off.
