Alarm troubleshooting

The most common reason for an alarm to sound is because the system has not been properly assembled.
Check that the air tubing has been properly attached to the device and patient interface (and humidifier if
used).
Notes:
•
The alarm log and alarm settings are maintained when the device is powered down and in the event of
a power loss.
•
If multiple alarms are active simultaneously, the alarm with the highest priority will be displayed first.
•
If an alarm activates repeatedly, discontinue use and return the device for servicing.
