13.0 ALARMS

Visual and auditory alarms tell clinicians and patients about the pump, controller, connections, and power supplies (batteries, AC adapter, DC adapter). A quick reference guide
for alarms is located in Appendix A. Alarm conditions, are classified as high, medium or low. Each of these alarms has a 1) unique sound, 2) visual display (flashing RED, flashing
YELLOW or YELLOW) and 3) message.
When an alarm occurs, two lines of text appear in the Controller Display. The first line describes the alarm and the second line tells you what to do. When an alarm is resolved,
there is no longer an alarm sound or a light displayed in the Alarm Indicator.
warning: A controller with a blank display or no audible alarm should be replaced.
