Troubleshooting
If there is a problem, try the following suggestions. If a problem cannot be solved, contact

Alarm troubleshooting

properly assembled. Check that the air tubing has been properly attached to the device and
patient interface (and humidifier if used).

•
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.
