Check Mask Fit
The optional Check Mask Fit feature can be enabled or disabled by your home care provider. This feature allows you
to check the fit of your mask prior to starting therapy. This is done by measuring the amount of leak. Put on your
mask assembly. Refer to your mask instructions if needed. Navigate to the Check Mask Fit screen under “My Setup,”
and press the control dial to initiate the check.
The device will deliver a test pressure while the screen counts down 40 seconds. A green bar indicates good fit, while
a red bar indicates improvement is needed. After the test, normal therapy will start and the screen will either display
a green checkmark or a red “X”. The green checkmark indicates that the leak found allows for optimal performance
of the device. The red “X” indicates that the leak may affect device performance, however, the device will remain
functional and deliver therapy.

Note:
If you choose to try to improve your mask fit, you can stop therapy, adjust the fit of your mask, and rerun
the Check Mask Fit. Refer to the instructions that came with your mask and headgear for the proper fitting
procedure.
Sleep Progress
Your device provides summary information about your therapy use each time the therapy is turned off. The screen
displays your “Three Night Summary.” It shows your nightly usage for the last 3 sleep sessions (measured in 24 hour
periods, ending at noon each day). The most recent session is displayed in the right hand bar, labeled with the number
of hours slept. A green bar indicates that you slept more than 4 hours, and a yellow bar indicates less than 4 hours of
use.
