The Metasys system provides customized preferences for the Metasys user interfaces. The preferences allow you to configure how the user interfaces behave, including the sounds and colors, the startup views, alarm priorities, and links from within the user interfaces to external applications. Preferences are divided into two categories: system preferences and user preferences. System preferences apply to all users who log in to the site or device and affect the performance and operation of the system. User preferences apply to a specific Metasys system user and define how information is displayed in the user interfaces. User preferences do not affect the operation of the system.
