Technical alarm and information messages
This section presents tables of technical alarm and information messages to help you
troubleshoot issues on the monitor.
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 or very low priority unless noted in the Message
column.
Alarm logs are not viewable by clinicians. However, all logs are transferred to Welch
Allyn on a regularly scheduled basis. In the event of an unplanned power failure, all
information, including device logs and patient data, are retained on the system.
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.
If you cannot resolve the issue, use the service tool to read the error log files or to
perform a functional test on the module reporting the message.
Note Performing functional tests on modules requires the service tool, Gold
edition.
