ATOM 3.0 OPERATING MANUAL
© 2002 Design, 2011 Doc. No. 12-5216-r02 (9/6/11)
Deco Stop Alt 3 (if Nitrox), information includes (Fig. 104):
> O2 accumulated* with O2% icon.
*This is the % of the per dive or per day allowed max limit of 300 OTU.
> Current PO2 value (ATA) with PO2 icon.
> FO2 Set Point (21 to 100%) for gas in use with FO2 icon.
> NX icon.
> Gas (tank) icon for gas in use (1, 2, 3).
• 5 sec or A (< 2 sec) - to revert to Main.
• L (press) - to activate Backlight.
CV (CONDITIONAL VIOLATION)
Upon ascent above the required Deco Stop Depth, operation will enter CV during which no off gassing credit will be given.
The audible will sound and the alarm LED will flash. The full TLBG and Down Arrow icon will flash (Fig. 105) until the audible is
silenced, then the TLBG will be solid.
• S (< 2 sec) - to silence audible.
> Down Arrow icon continues to flash until descent to below required stop depth (within stop zone), then full Stop icon (stop
bar with both arrows) will be on solid.
If you descend deeper than the required Deco Stop before 5 minutes elapse, Deco operation will continue with no off gassing
credit given for time above the Stop.
Instead, for each minute above the Stop 1 and 1/2 (1.5) minutes of penalty time will be added to required Stop Time.
> The added penalty (deco) time will have to be worked off before obtaining off gassing credit.
> Once the penalty time is worked off, and off gassing credit begins, required Deco Stop Depths and Time will decrease
toward zero. The TLBG will recede into the No Deco zone and operation will revert to No Deco mode.
DV 1 (DELAYED VIOLATION 1)
If you remain shallower than a Deco Stop Depth for more than 5 minutes, operation will enter DV1 which is a continuation of
CV* with penalty time still being added.
The audible will sound and the full TLBG will flash (Fig. 106) until it is silenced.
*The difference is that 5 minutes after surfacing from the DV1 dive, operation will now enter Violation Gauge Mode (VGM).
> The audible will silence after 10 seconds.
> Down Arrow icon continues to flash until descent to below required Stop Depth, then full Stop icon will be on solid.
DV 2 (DELAYED VIOLATION 2)
If the calculated Deco obligation requires a Stop Depth between 60 FT (18 M) and 70 FT (21 M), operation will enter DV2.
The audible will sound and the alarm LED will flash. The full TLBG will flash until the audible is silenced.
> The audible will silence after 10 seconds.
> Up Arrow icon flashes if 10 FT (3 M) deeper than the required Stop Depth.
> Once within 10 FT (3 M) of and below the required Stop Depth (Fig. 107), the Stop icon (both Arrows with Stop Bar) will be
displayed solid.
DV 3 (DELAYED VIOLATION 3)
If you descend deeper than the MOD*, the audible will sound and the alarm LED will flash.
Also, the graphic UP will flash in place of Current Depth (Fig. 108).
NDC and Max Depth will only indicate dashes signifying that you are too deep.
*MOD is the Max Operating Depth at which the unit can properly perform calculations or provide accurate display information. Refer to the specifications in the
back.
Upon ascending above the MOD, Current Depth will be restored, however, Max Depth will continue to be displayed as dashes
for the remainder of that dive. The Log for that dive will also display dashes for Max Depth.
