Before putting on the mask, place the pillows cushion tips into your nostrils. Choose the cushion size that sits comfortably under your nose without any gaps. Do not push the pillows gel bases into your nostrils.

Pulling the headgear over your head, gently hold the cushion over your nose. If needed, you can make adjustments while sitting up.

Insert the pillows cushion tips into your nostrils so that they sit comfortably under your nose without any gaps.

Adjust the top crown strap so that the headgear sits just above your ears, similar to glasses. If the side straps are too close to your eyes, loosen the top strap to move the side straps away from your eyes. The headgear should fit loose and comfortable.

Peel the tabs away from the straps, adjust the length evenly by pulling upward, and then press the tabs against the straps to reattach. The gel pads should sit under your cheek bones. The mask should rest comfortably against your face. Do not over-tighten.

As an option, you may slide the mask tubing through the headgear crown loop before pulling on the headgear. Using the headgear crown loop can help make some sleeping positions much more comfortable.

Now connect Nuance tubing to the flexible tubing that came with your device. Some air leaking is normal.

Assume different sleeping positions. Move around until comfortable. If there are any excessive air leaks, make final adjustments whil
