Use a standard conical connector if pressure readings and/or
supplemental oxygen are required.
Fitting
1. Lift and pull both mask clips away from the frame.
2. Ensure that the ResMed logo on the headgear is facing outwards and
is upright. With both lower headgear straps released, hold the mask
against your face and pull the headgear over your head.
3. Bring the lower straps below your ears, and attach the mask clip to
the frame.
4. Undo the fastening tabs on the upper headgear straps. Pull the straps
evenly until the mask is stable and positioned as shown in the
illustration. Reattach the fastening tabs.
5. Undo the fastening tabs on the lower headgear straps. Pull the straps
evenly until the mask is stable and sits comfortably on the chin.
Reattach the fastening tabs.
6. Connect the device air tubing to the elbow. Attach the elbow to the
mask by pressing the side buttons and pushing the elbow into the
mask, ensuring it clicks in on both sides.
7. Your mask and headgear should be positioned as shown in the
illustration.
Adjustment
If necessary, slightly adjust the position of the mask for the most
comfortable fit. Ensure that the cushion is not creased and the headgear
is not twisted.
1. Turn on your device so that it is blowing air.
Adjustment tips:

With air pressure applied, pull the mask away from your face to
allow the cushion to inflate and reposition onto your face.

To resolve any leaks at the upper part of the mask, adjust the
upper headgear straps. For the lower part, adjust the lower
headgear straps.

Adjust only enough for a comfortable seal. Do not overtighten as
this may cause discomfort.
