Troubleshooting
This section presents tables of technical alarm and information messages, as well as
problem descriptions that do not generate messages, to help you troubleshoot issues on
the monitor.
Note Problem descriptions without messages appear at the end of this section.
When the monitor detects certain events, a message appears in the Device Status area
at the top of the screen. Message types include the following:
• Information messages, which appear on a blue background.
• Very low-priority alarms, which appear on a cyan background.
• Low- and medium-priority alarms, which appear on an amber background.
• High-priority alarms, which appear on a red background.
Technical alarm messages are low priority unless noted in the Message column.
You can dismiss a message by touching the message on the screen, or, for some
messages, you can wait for the message to time out.
To use these tables, locate the message that displays on the monitor in the left column
of the table. The remainder of the row explains possible causes and suggests actions
that can resolve the issue.
Note Instructions to "Call for service" in the following tables mean that you
should contact qualified service personnel in your facility to investigate the
issue.
