# Typographic Conventions

Throughout this documentation, both in the Online Help System and in this printed User's Manual, various conventions are used to identify pertinent information.

- All Notes and Exceptions are placed in Italics. Notes and Exceptions represent important additional information. Also, some Help topics which are associated with the Help button within certain dialog boxes, have an italicized description of how to access the dialog box, appearing at the beginning of the topic, for the benefit of users who are referring to the printed manual version of the Help System.
- In the Online Help System, Links to other Help pages are underlined and green in color.
- Items that are ALL CAPITALS reference the names of keys, lights, LEDs, or when referring to a mode to which the RTU is placed (for example, PROGRAM mode).
