Informative alarms
These alarms are for information purposes.
Informative alarms are accompanied by either a low-
pitched “gong” sound that repeats about once a
second, or a high-pitched “train whistle” type of sound.
If you get an informative alarm, there is a problem that needs your attention.
Take the following action:
 Read the message on the monitor’s display.
 For specific help with any message, tap the help button if one is
available on screen.

Use this chart to see what the message means and what to do.
