To use the oral inflation hose place the very end of the bite on mouthpiece
between your teeth horizontally and make a seal around it with your lips.
Now bite down gently to open it and blow into the hose. No force should be
required.
If you are having difficulty inflating the wing check the orientation of the bite
on mouthpiece as it will only open when you bite on it in the horizontal axis.
Also make sure that you are biting at the very end of the mouthpiece as it will
not open if you are biting further up.
You should practice doing this before you go diving until you become familiar
and comfortable with the technique.
