Display Backlighting
The display will normally be unlit. Press any key once to activate backlighting. This will
illuminate the display without deactivating Auto Scroll.
Auto Scroll
The display will normally be in the Auto Scroll mode, continually cycling through the sub-
menu items at a two-second interval. In Auto Scroll mode the operator can quickly view menu
items without the need to press any keys.
Single Step
Pressing either arrow key will activate Single Step mode, allowing the operator to step
through the individual menu items. Each press of the arrow key will step up or down through
the sub-menu items. Press ESC to return to the Auto Scroll mode.
Direction Indicator Symbols
The rightmost character of the display (may appear on either line) indicates the proper
key function when manually scrolling. Where more than one choice is available multiple
characters will appear. The following characters or text may appear:
Access more menu items by pressing either the UP or DOWN arrow keys.
Use the ENTER key to select this function.
Use the ESCAPE key to leave the selected function without altering any values or to go back
to the previous menu in the display.
Press UP or DOWN arrows to change a display value or mode. Press ESCAPE to leave this
menu item without making any changes (and go back to the previous menu). Press ENTER
to save the change into memory. This type of multiple display choice is normally available in
the programming mode.
