Oceanic BC Mode D'emploi page 13

Figure 2 shows the hand position for using the power inflator to inflate and
the Rapid Exhaust Valve to deflate.
ManualInflation
The button on the end of the mouthpiece is an inflate/deflate manual
actuator that allows air flow in to, or out of, the BC. To inflate orally, bring
the mouthpiece to your lips, begin to blow into the hole, and only then
press the manual inflate/deflate button with your forefinger.
Blowing into the mouthpiece immediately prior to pressing the end button
purges the mouthpiece cavity of water. This will result in less water entering
the BC potentially prolonging bladder life. Some air may continue to leak
into the surrounding water when you are orally inflating the BC, even after
you have released the inflate/deflate button. This is normal and will not
impede the efficient oral inflation of the BC.
PowerInflation
Power inflation of the BC can be accomplished if the inflator's Quick
Disconnect (QD) inflator hose is attached to your regulator first stage by
an Authorized Oceanic Dealer. This allows the use of low pressure air to
inflate the BC without having to remove the regulator from your mouth.
Minor adjustments in buoyancy can be made easily with one hand using
the deflate and power inflate buttons on the inflator.
