Aqua Lung Airsource Quick Disconnect - Manual (Page 12)

The oral inflation/deflation valve is secondary means for venting air from the BC.
Most users vent air through the dump valves. However, you may find it easier
to expel the last portion of air remaining in a nearly empty BC by utilizing the
oral inflation valve.
1. Move into an upright position so that you can hold the Airsource above the bc.
2. With the Airsource in the left hand, raise the assembly to a position nearest
the surface of the water.
3. Depress the oral inflation/deflation button allowing air to exhaust in small
increments until the desired buoyancy is achieved.
4. release the button allowing the valve to close.
BACk Up SECOND STAGE REGULATOR
The Airsource is a high performance, pneumatically balanced second stage
regulator, and it operates the same as a standard second stage regulator.
To breathe, put the mouthpiece in your mouth. Purge the water by either
pressing the purge button, or exhaling slowly and continuously. You should
test the breathing performance of the Airsource before each dive.
In the event of an emergency air sharing situation, the assisting diver should offer
their primary second stage to the diver requesting to share air. The Airsource then
becomes the primary regulator for the assisting diver.
While using the Airsource as your second stage regulator, all inflation and
deflation procedures as outlined in this manual are still applicable.
Oral Deflation
WARNING: The procedure to deal with an Emergency Out-of-Air situation
should be reviewed before every dive. Make sure your dive buddy is
familiar with the operation of the Airsource and what role it plays in an
out-of-air situation.
NOTE: Do not hold the oral inflation/deflation button open after all the air has
been exhausted. Doing so may allow water to enter the BC. Also, whenever
inflating or deflating your BC, be sure to make small but frequent adjustments.
This will minimize the amount of water entering the BC.
