2. Place the cushion under your nose and ensure it sits comfortably
against your face. With the ResMed logo on the headgear facing out,
pull the headgear over your head. The top headgear strap should sit on
top of your head and not too far forward or back.
3. Bring the lower headgear straps under your ears and attach the
magnetic clips to the frame.

Adjusting your mask
• With the device turned on and blowing air, adjust the position of the
cushion for the most comfortable fit under your nose. Ensure that the
cushion is not creased and the headgear is not twisted.
• The top headgear strap should sit on top of your head and not too far
forward or back. Reposition the strap if needed to ensure the cushion
has a good seal under the nose.
• To fix any leaks around the nose, pull the cushion slightly away from
the face and reposition the cushion so that it sits comfortably under
the nose. Adjust the upper headgear straps, if required.
• To fix any leaks around the mouth, adjust lower headgear straps.
Adjust only enough for a comfortable seal and do not overtighten.
