Change Symbology.

Therefore, except when a number is added at the end of a sequence (in which case the next consecutive number is used), paragraphs, illustrations, tables, and pages are numbered by adding an alphabetical suffix. The same method is used for added pages, except that these pages are not added between a right-hand (odd numbered) and a left-hand (even numbered) page. When new material is added to a right-hand page, any overrun is carried to the left-hand page. Any overrun from this is placed on an added page. Therefore, added pages are always assigned even numbers, such as 2A, 2B, 4A, or 4B. Each page with changed or added material bears the word “change...” placed at the bottom of the page (fig. 2-9). For foldout pages, the change number is placed in the lower, outer corner of the page beneath the figure title. This change number requirement applies to all added pages, including those placed at the end of a manual. Change Symbology. Usually, text and table changes, including new material on added pages, are identified by a vertical line or change symbol in the margin. This line or symbol extends the entire length of the affected material. The line is placed on the outer margin for double-columned material, and in the margin opposite the binding edge for single-columned material (fig. 2-10). There is one exception. Pages with emergency markings (black diagonal lines around three edges) may have the vertical line or change symbols along the inner margins. When a page is changed, previous change symbols on a page are deleted. Symbols show current changes Figure 2-9.—Supplement format, conventional manual (paragraph illustration and page numbering). 2-9
