Airsource Owner's Manual
The oral ination/deation valve is secondary means for venting air from the BC.
Most users vent air through the dump valves. However, you may nd it easier
to expel the last portion of air remaining in a nearly empty BC by utilizing the
oral ination 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 ination/deation 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 press-
ing 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 of-
fer 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 ination and
deation procedures as outlined in this manual are still applicable.
NOTE: Do not hold the oral ination/deation button open after all
the air has been exhausted. Doing so may allow water to enter the
BC. Also, whenever inating or deating your BC, be sure to make
small but frequent adjustments. This will minimize the amount of
water entering the BC.
Oral Deation
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.
