Using the HumidAire 2i Warm-up Feature*
If using a HumidAire 2i with the device, you can use the Warm-
up feature to pre-heat the water in the humidifier prior to
starting treatment. The humidifer will be automatically
detected when the device is turned on and the standby screen
will give you the option to start warming up the humidifier.
After stopping treatment, the device will continue to blow air
gently to assist cooling of the heater plate.
* If you do not have a H2i attached and/or your clinician has not enabled Ramp time, these options
will not appear.
Ramp Time*
Ramp time is a feature which can be enabled by your clinician.
If you have difficulty becoming accustomed to the full pressure,
select a ramp time. The airflow will start very gently and slowly
increase to full operating pressure over the selected ramp time.
If your clinician has set a maximum ramp time, the Set Ramp
option is displayed on the Patient Standby screen. Ramp time
can be altered in five-minute increments (from OFF to a
maximum ramp time set by your clinician) by using the Up/
Down key.

Using the Mask-Fit Feature
This device includes a mask-fit feature to help you fit your mask properly. If a Ramp time is
selected, the mask can be adjusted at a pressure closer to the prescribed pressure. To use
the mask-fit feature:
1 Fit your mask as described in the user instructions.
2 Hold down the Start/Stop key for at least two seconds until air pressure delivery starts1.
The flow generator will ramp to the mask-fit pressure2and will remain at this pressure
for three minutes.
3 If necessary, adjust your mask, mask cushion and headgear to reduce leak and check
your mask-fit star rating again on the LCD screen.
4 After three minutes, treatment will begin.
•If you do not wish to wait three minutes, hold down the Start/Stop key for at least
two seconds and treatment will begin immediately.
•If you press the Start/Stop key for less than two seconds, the device will return to
standby mode.
Stopping Treatment
To stop treatment at any time, remove your mask and press the Start/Stop key
or
if the SmartStart function is enabled, simply remove your mask and treatment will end
(SmartStop is not applicable with the "Mir Full" mask setting and certain alarms; see
“SmartStart™” on page 10).
1 The mask-fit feature can also be accessed from the Patient Settings Menu.
2 The mask-fit pressure is the set treatment pressure or 10 cm H2O, whichever is greater.
The LCD also displays a mask-fit star rating from zero to
five stars. Three to five stars indicate a good fit. Zero to
two stars indicate that you should adjust your mask.
The mask-fit star rating display disappears after three

11The Alarms
English
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.

use of the device, the air filter needs to be replaced every six months (or more often if your
device is in a dusty environment). To replace the air filter:
1Remove the air filter cover at the back of the device.
2Remove and discard the old air filter.
3Insert a new filter with the blue tinted side facing out.
4Replace the air filter cover.
WARNING
Do not wash the air filter. The air filter is not washable or reusable.
