Log Data 1, information includes (Fig. 34):
> Log Mode (book) icon.
> Max Depth with MAX and FT (or M) icons.
> Graphic DSAT (or Z+), the Algorithm selected.
> Graphic EDT with Dive Time (hr:min).
> Graphic SURF and pre dive SI (hr:min), 0:00 if Dive # 1, 9: - - if > 9:59, with Time (clock) icon.
> Temperature (minimum that dive) with ° icon and graphic F (or C).
> TLBG with the max segment flashing, others fixed up to end of dive accumulation. All segments flashing if a Violation.
Blank if GAUG.
> VARI, max Ascent Rate sustained for 4 sec.
> Nx icon, if Nitrox.
• S (< 2 sec) - to access the dive's Log Data 2 screen if Nitrox, or revert to the Preview screen if Air or a Violation.
• L (press) - to activate Backlight.
Log Data 2 (Nitrox only), information includes (Fig. 35):
> Log Mode (book) icon.
> Graphic GAS 1 (or 2 or 3), in use when dive ended.
> Graphic FO2 with FO2 Set Point (or graphic Air) for Gas in used when dive ended.
> Graphic PO2 with value of Max PO2 achieved.
> Nx icon.
> O2BG with O2 icon, accumulated when dive ended.
• S (< 2 sec) - to revert to the Preview screen.
• L (press) - to activate Backlight.
SET F (FO2)
Each Gas has an individual FO2 and an associated PO2 Alarm setting.
Default settings are FO2 Air with no PO2 value for Gas 1, and Off for Gas 2 & 3. Settings revert to the defaults when 24 hours
elapse without conducting a dive.
When FO2 is set for Air -
> calculations are the same as when FO2 is set for 21%.
> it remains set for Air until set for Nitrox (21 to 100%).
> O2 data (such as PO2, O2%) will not be displayed at any time during the dive, on the surface, or in Plan mode.
> MODs (Max Operating Depths) will not be displayed on the FO2 set screen.
> internally, it will keep track of O2 data for use if FO2 is subsequently set for Nitrox for repetitive dives.
When FO2 is set for Nitrox -
> The Air option will not be displayed as an FO2 setting until 24 hours elapse after the last dive.
When FO2 is set for OFF (Gas 2, 3) -
> That Gas will not be available in the Gas Switch routine during dives (no Switch To - screen).
FO2 50% Default -
> When the Default is set OFF, FO2 values will remain set at their last settings saved until 24 hours elapse without conducting
a dive.
> When the Default is set ON and FO2 is set for Nitrox, 10 minutes on the surface after that dive the FO2 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 FO2 is set before the dive.
> FO2 will continue to reset to the Default after repetitive dives until 24 hours elapse with no dive, or the Default is set OFF.
SET F (FO2) MENU
Menu selections (Fig. 36) >> Gas 1 >> Gas 2 >> Gas 3 >> FO2 Default.
• S (< 2 sec) - to access Set F Menu while the selection Arrow icon ( > ) is next to Set F on the NORM Menu.
• A (< 2 sec) - to step down (forward) through selections.
• M (< 2 sec) - to step up (back) through selections.
• S (< 2 sec) - to access selection indicated by Arrow icon ( > ).
The last setting saved, or the default, is displayed next to each Menu item.
SET GAS 1 FO2/PO2, information includes:
> Max Depth allowed for the PO2 Alarm setting displayed, blank when Air.
> Graphic GAS1.
> Graphic FO2 with setting Air or 21 to 100 flashing (Fig. 37A/B).
> Graphic PO2 with Alarm value set.
> Nx icon (if Nitrox, numerical values), blank if Air.
• A (press/hold), while the FO2 digits are flashing - to scroll upward through the Set Points from Air to 21 through 100 in 1%
increments, at a rate of 8 per second.
>> The scroll will stop when the button is released, or momentarily at 32, then 50, then 80 (%).
