NORM/GAUG SET MODES
SURF MAIN > SET GAS > SET A > SET U > Serial Number.
A & S (2 sec) - to access then step through of the sequence.
Alarms (Set A) and Utilities (Set U) set points can also be set/changed using the PC/Mac settings upload program.
Set Gas (FO2 & PO2 Alarm) entries must be made using only the push buttons.
Settings remain at the values set until they are changed, and saved, as described by the following sections.
SETTING GAS FOR NITROX DIVES
For each value of FO2, the MOD (Max Operating Depth) that can be achieved for the PO2 Alarm value set, will be displayed.
When the FO2 50% Default is set On and FO2 for Gas 1 is set for a numerical value, 10 minutes on the surface after that dive,
the FO2 for Gas 1 will be displayed as 50 and further dives will be calculated based on 50% O2 for oxygen calculations and
21% O2 for Nitrogen calculations (79% Nitrogen) unless the FO2 for Gas 1 is set before the dive.
FO2 for each Gas continues to reset to the FO2 50% Default after subsequent repetitive dives until 24 hours elapse after the last
dive, or the FO2 50% Default is turned Off.
When the FO2 50% Default is set Off, the FO2 for each Gas will remain at the last settings for the remainder of that series of
repetitive dives.
The default FO2 for Gas 1 and 2 each new dive Period is AIR.
When FO2 is set for AIR, the calculations are the same as when it is set to an FO2 of 21%. When FO2 is set to AIR, it remains
set for AIR until it is set for a numerical FO2 value (21 to 100%).
When FO2 is set only to AIR, the O2 and PO2 values and/or warnings will not be displayed during the dive.
MODs affected by the PO2 value set will not be displayed when FO2 for Gas 1 is set to AIR.
Internally, the Talis keeps track of the O2 so that if FO2 for a Gas is subsequently set for a numerical value, the O2 accumulated
during previous dives will be accounted for in the next Nitrox dive (during that dive period and series of repetitive dives).
Once FO2 is set for a numerical value (21 to 100%) and a dive is made, the AIR option is disabled until 24 hours elapse after
the last dive. The AIR option will not be displayed in Set Gas until a full 24 hour Surface Interval has elapsed.
If the FO2 50% Default is set Off, FO2 for each Gas will remain at the values previously set until they are changed. If the FO2
50% Default is set On, FO2 will Default to 50% after the dive.
SET GAS (FO2 & PO2 ALARMS)
Group selections >> Gas 1 >> Gas 2 >> FO2 50% Default.
• A & S (2 sec), while viewing NORM Surface Main - to access the SET GAS lead-in screen (Fig. 27).
• A (< 2 sec) - to access Set Gas 1.
SET GAS 1, information includes (Fig. 28):
> Graphic GAS (when Air), or PO2 (when Nitrox).
> Max Depth allowed for the PO2 Alarm value displayed with MAX and FT (or M) icons (when Nitrox), blank when Air.
> Tank 1 icon, representing Gas (mix) 1.
> Graphic Air, or the Nitrox value of 21 to 100%, flashing.
• S (press/hold) - to scroll upward through FO2 set points 8/sec from AIR to 21 through 100% in incrementsof 1 %.
The scroll will stop when S is released, or momentarily at 32%, then 50%, then 80%, 50%, then stop at Air (or 21%).
• S (< 2 sec) - to step upward through the FO2 set points one at a time.
• M (< 2 sec) - to step back (down) through the FO2 set points one at a time.
• A (< 2 sec) - to save the FO2 setting and flash the PO2 Alarm digits if Nitrox, or access Set Gas 2 if Air.
• S (< 2 sec) - to step upward through the PO2 Alarm set points from 1.00 to 1.60 ATA in increments of .05 ATA.
• M (< 2 sec) - to step back (down) through the PO2 Alarm set points one at a time.
• A (< 2 sec) - to save the PO2 Alarm setting and access Set Gas 2.
• A (2 sec) - to step back to the previous screen (SET GAS), without changing the setting.
• A & S (2 sec) - to revert to the SET GAS screen.
• M (2 sec) - to revert to the Surface Main.
• Revert to the Surface Main after 2 minutes, if no button is pressed.
