2.2 Menu Bar
The parameters on the display are controlled by the menu bar, which is located at the bottom
of the LCD. The function keys (F1, F2, and F3) are used to navigate through all the levels and
choices of the menu bar. Refer to the menu tree for a clarification on the layout of all the
levels.
The top level of the menu is the home menu. It can be accessed anytime by pressing the
HOME key. There are three variations of the home menu: the input home menu, the output
home menu, and the pulse home menu.
In the input home menu the only active options are [MENU] and [LIGHT]. The [MENU] option
is used to enter the next level of the menu bar, the main menu. Press the corresponding
function key (F1) to enter the main menu. The [LIGHT] option is used to turn on the LCD
back light. Press the corresponding function key (F2) to turn on the back light.
In the output home menu there are three active options, [MENU], [LIGHT] and [STEP] or
[RAMP]. The first two options work the same as in the input home menu. The third option is
selectable in the Auto Function Menu and is used to turn on and off the selected auto
function. See Section 4.2, Using the Automatic Output Functions. Also leaving this menu or
pressing the Home button will stop the auto functions.
