Stowing Instructions
To stow the oxygen mask accomplish the following:
• Set the “N/100%” regulator control to “100%.”
• Ensure that the “EMERGENCY” oxygen control knob is off.
• 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 and pull it downward so the cross straps are below the
facepiece. Allow the excess harness to hang downward.
