The main menu in Omnilert includes a section to view any current system notifications. This section will display any notices about issues impacting the Omnilert network.
If there are any active/new notices, you will see a red indicator (shown below) to draw your attention to the System Notices section.
New/unread notifications will show a "new" icon next to their title in red.
Once a notice has been reviewed, it can be marked as read by clicking the Mark as read button for the appropriate notice.
