POST-DIVE MAINTENANCE
OPERATION
Buoyancy on the surface
In order to ensure maximum buoyancy on the surface,
before getting into the water (or directly afterascending)
inflate the BC using inflator button. Stop inflating the BC
when the automatic dump valve activates.
Descent
In order to descend, press the purge button holding the
inflator over your head. Use the purge button with care,
as releasing too much air may result in an uncontrolled
descent.
Neutral buoyancy
Maintain neutral buoyancy for a given depth during the
dive, using the inflator and purge buttons as needed.
In order to ensure precise control over buoyancy you sho-
uld press the inflator button for a short moment. If more
air needs to be added to the BC, press the inflator button
for a short moment several times.
During release of air from the BC hold the inflator over
your head, so the air may escape freely.
Ascent
Ascending too quickly may result in decompression
sickness. Therefore you must control the rate of ascent
by gradually releasing the expanding air from the BC with
the purge button.
DANGER
BEFORE JUMPING INTO DEEP WATER FROM A
BOAT OR A BANk INFLATE THE BC USING THE
INFLATOR BUTTON. GETTING INTO WATER WITH
THE BC NOT FULLY INFLATED MAY RESULT IN
DROWNING!
DANGER
ASCENDING OR REDUCING THE DEPTH LEVEL
TOO QUICkLY MAY RESULT IN DECOMPRESSION
SICkNESS (DCS). ALWAYS PAY ADEQUATE ATTEN-
TION TO BUOYANCY CONTROL AND RESPECT THE
ASCENT RATE LIMITS.
