Mask Fit
Mask Fit is designed to help fit
the mask properly to the patient.
The Mask Fit feature delivers CPAP
pressure for a three-minute period,
prior to starting treatment. During
this time, the mask can be adjusted
to minimize leaks.
To use Mask Fit:
•Fit the mask as described in the mask
user guide.
•Press for at least three seconds.
One of the MASK FIT screens is displayed
(as shown on the right).
•If necessary, adjust the mask, mask cushion
and headgear until there is a secure and
comfortable fit. After three minutes, the
pressure reverts to the set pressure and
treatment will begin. You can end Mask Fit
at any time by pressing .
