Press and release the Right (Select) button to toggle between Gauge ON and OFF.

Press and release the Left (Advance) button to accept the setting and advance to DEMO: NI-O2 with CUR (or NEW) flashing (Fig. 86).

When set for NEW, calculations are based on zero residual nitrogen and oxygen loading (a clean dive).

When set for CUR, calculations take into consideration any residual nitrogen and oxygen remaining from previ- ous 'actual' dives.

Subsequent (repetitive) Simulated dives do not take into consideration previous Simulated dives.

Press and release the Right (Select) button to toggle between NEW and CUR.

Press and release the Left (Advance) button to accept the setting and advance to DEMO: PSI (or bAr) with OFF, CYL, or 3000 flashing (Fig. 87).

When set for OFF, no calculations are made and no displays appear relating to tank pressure.

When set for CYL, Air Time Remaining is calculated based upon actual pressure of the tank that the Pro Plus 2 is connected to.

When set for 3000, Air Time Remaining is calculated based upon a simulated tank pressure of 3000 psi.
