The Alarms
This device is fitted with alarms to alert you to changes that will affect your treatment.
Alarm Mute Key
You can mute an alarm by pressing the Alarm Mute key once. Pressing this key a
second time will un-mute the alarm. If the problem is still present, the alarm will sound again
after two minutes. An alarm LED will remain lit for as long as the problem is present. The
Title bar of the LCD will display the alarm description while the alarm is muted.
Testing the Alarm
When the device is turned on, the LEDs will flash and the alarm will beep to confirm that the
alarm is working.
Setting the Alarm Volume
You can set and test the alarm volume from the Patient Options Menu. The alarm will beep
at the selected volume when you press Enter.
All menus remain available during an alarm. Treatment screens are not viewable during an
alarm condition.
Alarms 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 flow
generator and mask (and humidifier if used).
When an alarm has been activated, the LCD screen will display either alarm information or
recommended instructions for you or your clinician.
Note: The alarm actions listed below are based on having the appropriate alarm settings for
your therapy. When an alarm is activated, consult your clinician.
!
CAUTION
In the event of power failure or machine malfunction, remove the mask to avoid
rebreathing your exhaled air.
