Publication Revision Letters
When a GE publication is revised, a letter is placed at the end of the publication number. For
example, in the publication number GFK-0356Q, the letter Q at the end indicates the version of the
manual. Manuals are revised when there are changes or additions to the products or product lines
covered in the manual. Since this is a continual process revision letters are not included in this
appendix, except in a few special cases. Therefore, when ordering these publications, ask for the latest
version.
