5.15 Check Mask Fit
The optional check mask fit feature can be enabled or disabled by the 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 start 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.
5.16 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 (meas-
ured 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.
5.17 Altitude Compensation
This device automatically compensates for altitude up to 7,500 feet. No manual adjustment is necessary.
