The Network Management System OMS for Water User’s Guide describes how to use the features in the NMS Outage Management System for Water. It provides instructions for completing common tasks and provides descriptions of the fields, windows, buttons, and menus you will use to perform those tasks. The instructions and descriptions in this guide are based on the default product configuration for a user with full authority to use all functionality. Because the system is highly configurable, your system may look and behave differently.
