If there is a problem, try the following suggestions. If the problem cannot be solved, contact your care
provider or ResMed.

Alarm troubleshooting

The most common reason for an alarm to sound is because the system has not been properly
assembled or a Learn Circuit has not been correctly performed for each program.
Notes:
• The alarm actions listed below are based on having the appropriate alarm settings for the patient's therapy.
When an 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 an alarm activates repeatedly, discontinue use, switch to a backup ventilator and return the device for
servicing.
If the alarm log reaches its storage capacity, the oldest data will be discarded to allow new entries to be
written to the log.
