position and not be blocking the large opening in the mask swivel.

WARNING
DO NOT place the mask on your face unless the PAP machine is
turned On. Otherwise, injury may occur.
Fitting the Mask
NOTE: For this procedure, refer to SECTION D in the supplemental sheet.
1. Before fitting the mask, unfasten one or both of the headgear clips
from the mask frame (D-1).
2. Place the mask on the face with the headgear straps behind the head
(D-2).
3. Fit the mask loosely over the nose and mouth with minimal pressure.
4. Reattach both headgear clips to the mask frame (D-2).
5. Adjust the mask as follows:
A. Lift the forehead lever to the unlocked position (D-3).
B. Slide the forehead support up or down until it contacts the
forehead and the upper portion of the cushion lightly touches the
bridge of the nose (D-3).
C. Lower the forehead lever to lock the forehead support in the
desired position (D-4).
ƽ
WARNING
DO NOT pull the straps too tight. This can cause skin irritation and
may deform the cushion causing a leak. If the mask and headgear are
adjusted correctly and a problem persists, contact your health care
professional.
6. Adjust the strap length as needed using the hook and loop fasteners
(D-5 and D-6).
NOTE: If a leak occurs, adjust the forehead support. If this does not work, tighten
or loosen the headgear straps by readjusting the hook-and-loop fasteners.
NOTE: Proper mask fit should allow full contact of the cushion without excessive
pressure on the face.
