6.With the IVS/RVS lever set to (-) depress the purge button momentarily to blow out any dust or debris which ray haw 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 toss of your air supply during entry or while making a long surface swim. Adjustments can be made below the surface. When you are ready to submerge, place the second stage in your mouth and set the IVS/RVS switch in the plus (+) position. If present, torn the inhalation control knob out (anti-clockwise) until the regulator breathes comfortably without leaking or being undesirably sensitive. |
