Documentation Conventions
Before describing the various features of the DNA Engine Tetrad 2 cycler, let’s define
some “common ground” conventions.
• << >> will be used to indicate actual keys on the control panel, such as
<<ENTER>>, <<1>> and <<LEFT>>.
• < > will be used to indicate windowed menu items or buttons, such as <PRO-
GRAMS>, <RUN> and <UTILITIES>.
• Italics will be used to indicate windowed items that are not drop down menu
items or buttons, such as Calculated, Block, and Tracking. Typically, these will be
parameter selection items.
• Select is meant to be synonymous with click on, point-and-click, and any
phraseology implying selection of menu or option items with the mouse. In some
instances, selection is also possible by clicking the <<Enter>> button.
