Use of the REV eliminates water entry even if the Exhaust Valve remains open after all air is vented from 

the BC.

BC INFLATION USING THE MANUAL INFLATE/DEFLATE BUTTON

The Round Button located on the right side of the Mouthpiece is an Inflate/Deflate manual actuator that al-

lows air flow in to, or out of, the BC.  To inflate orally, place the Mouthpiece in your mouth, and after you 

begin (and continue) to blow in, press the Button with your thumb.  This procedure purges the mouthpiece 

cavity of water, resulting in less water entering the BC, potentially prolonging Bladder life.  

Some air may continue to leak in to the surrounding water when you are orally inflating the BC, even after 

you have released the Inflate/Deflate Button.  This is considered normal and will not impede the efficient 

oral inflation of the BC.

BC DEFLATION USING THE MANUAL INFLATOR/DEFLATOR BUTTON

To deflate the BC through the Mouthpiece, hold the lower (power) unit higher than the top of the BC and 

depress the Round Button located on the right side of the Mouthpiece to vent the air from the BC.  

To ensure complete deflation of the BC, the Mouthpiece must be held higher than the top of the BC.  While 

underwater, you will hear the air as it bubbles out through the Mouthpiece.  

To prevent entry of water into the BC, be sure to release the Button before all bubbles stop flowing.  To 

help eliminate unwanted water entry, use the Rapid Exhaust Valve method of 

deflation.

REGULATOR OPERATION

In the event that it is necessary for you to share air with another diver, you should offer your 

Primary Second Stage to the diver and you should use the AIR XS II Regulator.  Although the 

AIR XS II Regulator will function properly with the Purge Button facing up or down, Oceanic 

recommends an operational position with the Purge Button facing up, similar to other Second 

Stage positioning.
