6. If the regulator is not attached to the facepiece, proceed as fol-
lows:
a) Align the two flats of the regulator outlet port with the correspond-
ing flats in the facepiece port (the red purge valve on the regula-
tor will be in the 12 o'clock position). Insert the regulator into the
facepiece port.
b) Rotate the regulator counterclockwise (as viewed from inside of
facepiece) until the red purge valve knob is on the left side of the
facepiece. The lock tab on the regulator will lock into the facepiece
retainer with a "click." When the lock tab is properly engaged, the
regulator will not rotate.
7. If the hose to the breathing regulator is equipped with a quick
disconnect, check that the quick disconnect is engaged properly
by tugging on the coupling and that the HEADS-UP DISPLAY
plug is properly aligned and fitted into the mating socket. See
