Oral Inflation
The oral inflator is a secondary means for adding air to the flotation cell. It may
be used when you are unable to, or do not wish to add air with the power infla-
tor.
1. Before depressing the oral inflation/deflation button (Figure 10), exhale a
small amount of air into the mouthpiece in order to purge any water that may
be trapped. This will reduce the amount of water that may be introduced into
the bc.
2. After the water is purged and without removing the mouthpiece from your
mouth, immediately depress and hold down the large red oral inflation/de-
flation button and, with the same breath, continue to exhale into the mouth-
piece. Release the oral inflation button immediately after exhalation in order
to stop the release of air from the flotation cell.
CAUTION: If when pressing the red inflation button there is no airflow,
confirm the Cut-off valve is in the air on (down) position.
NOTe: Whenever inflating or deflating your BC, be sure to make small
but frequent adjustments. Larger adjustments make the maintenance
of neutral buoyancy difficult.

NOTe: It is important to prevent sand and other debris from entering
the mouthpiece. These objects can contaminate the valve mechanism
and, under certain conditions, prevent it from closing completely. If this
should occur, operate the oral inflator several times while shaking it
underwater. If this action is not successful, terminate the dive until the
situation is remedied.
