Stowing Instructions
To stow the oxygen mask accomplish the following:
• Set the regulator to “100%.”
• Ensure that the cloth liner is secured at the top of the stowage box and is
laying flat against all interior sides of the box.
• Coil the supply hose into the bottom of the stowage box, making the
largest diameter possible.
• Ensure that the harness is completely deflated.
• Hold the mask by the regulator with the facepiece down and the inside
of the mask toward you.
• Grasp the harness “cross,” then pull it downward toward the top of the
facepiece and tightly roll the mask around it. Allow the excess harness
to hang down from the top of the rolled facepiece.
