your goal will be displayed through a pop-up screen congratulating you.

AHI If enabled by your provider, this feature displays the nightly Apnea/Hypopnea
index (AHI) value for the most recent one day time frame.
Mask fit This screen displays how your mask fit during the most recent one day time
frame.
A display of "Good fit" indicates that the leak found allows for optimal
performance of the device. A display of "Adjust fit" indicates that the leak may
affect device performance, however, the device will remain functional and
deliver therapy. If "Adjust fit" displays, adjust your mask to reduce the leak
before starting therapy again. By tapping on "Adjust fit" or "Good fit", you can
choose to initiate a mask fit check.
To run a mask fit check, put on your mask assembly and tap "Start" to begin a
mask fit check.
