6. With the IVS/RVS lever set to (–) depress the purge button
momentarily to blow out any dust or debris which may have
entered the second stage. Release the purge button and listen
to ensure that the second stage does not continue to flow any air
after the purge button is released.
7. Inhale slowly and deeply from the regulator several times. The
regulator must deliver enough air for you to breathe easily without
noticeable resistance.
8. Check to ensure that the submersible pressure gauge is
displaying an accurate measurement of the air pressure inside the
cylinder.
9. Check to ensure that the IVS/RVS control switch is set to “MIN” (–
). If present, gently turn the inhalation control knob completely “in”
(clockwise), only until it stops. Do not apply excessive pressure.
These settings will help to minimise any loss of your air supply
during entry or while making a long surface swim. Adjustments
can be made below the surface.
During the Dive
When you are ready to submerge, place the second stage in your
mouth and set the IVS/RVS switch to your desired position. If present,
turn the inhalation control knob out (anti-clockwise) until the regulator
breathes comfortably without leaking or being undesirably sensitive.
As you descend, you may want to turn the inhalation control knob
further out to make breathing easier. This will be particularly true on
deep dives where the air density increases.
