Troubleshooting

If there is a problem, try the following suggestions. If the 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 actions listed below are based on having the appropriate alarm settings for the
•
patient's therapy. When a user adjustable alarm is activated, re-confirm the alarm settings.
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.
