Aqua Lung Airsource Quick Disconnect - Manual (Page 9)

BC Inflation
Just as with a conventional inflator, power (MP) or oral inflation can be
utilized when using the Airsource. Both procedures need to be practiced to
become familiar.
Medium Pressure (MP) Power Inflation
The power inflator is a primary means for adding air to the flotation cell. The
power inflation system enables you to inflate the BC simply by pressing the
small red inflation button (Figure 8). With practice you will soon be able to
quickly make buoyancy adjustments without interrupting your diving activity.

CAUTION: If when pressing the red inflation button there is no airflow,
confirm the medium pressure (MP) inflator hose is attached securely.
NOTE: Whenever inflating or deflating your BC, be sure to make small but
frequent adjustments. Larger adjustments make the maintenance of neutral
buoyancy difficult.
