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