Reassembling your mask
1. With the gray side of the headgear facing out, insert each end of the
headgear band over the stabilizers through the buttonholes.
2. Secure the headgear by pulling the buttonholes over the ends of the
stabilizers.
3. Holding the mask frame, stretch the headgear lightly to ensure it is
securely attached. Ensure that the headgear band is not twisted.
4. Align the notch in the cushion to the tab on the mask frame. Firmly
push one side of the cushion onto the frame, then repeat on the other
side. Push down all the edges of the cushion onto the frame to ensure
that the edges are completely flat.
