OCL OPERATING MANUAL
© 2002 Design, 2014 Doc. No. 12-5378-r01 (4/9/15)
Deco Stop Alt 3 (if Nitrox), information includes (Fig. 79) -
> % O2 with O2sat icon
> Current PO2 value (ATA) with icon
> FO2 value set for the Gas in use with icon
> Gas 1 (or 2) icon, the one in use
• A (< 2 sec) - to revert to the Main.
• Revert to the Main in 10 seconds, if A is not pressed.
• L (press) - to operate the 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 ash. The full TLBG and Down Arrow with Stop Bar icon will ash (Fig. 80)
until the audible is silenced, then the TLBG will be solid.
• S (< 2 sec) - to silence the audible.
> Down Arrow with Stop Bar icon continues to ash until descent to below required Stop Depth (within stop zone), then
the 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 gas-
sing credit given for time above the Stop. Instead, for each minute above the Stop 1-1/2 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. Again, the audible will sound and the full TLBG will ash for 10 seconds (Fig.
81).
*The difference is that 5 minutes after surfacing from the dive, operation will now enter Violation Gauge Mode.
> Down Arrow icon continues to ash 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, the alarm LED will ash, and the full TLBG will ash for 10 seconds (Fig. 82).
> Up Arrow icon ashes if 10 FT (3 M) deeper than the required Stop Depth.
> Once within 10 FT (3 M) of and below the required Stop Depth, 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 ash. Also, the Up Arrow will ash,
and Current Depth and Max Depth will only indicate 3 dashes ( - - - ) signifying that you are Too Deep (Fig. 83).
*MOD is the Max Operating Depth at which the unit can properly perform calculations or provide accurate display
information. Refer to the Specications 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.
VGM (VIOLATION GAUGE MODE)
During NORM dives, operation will enter VGM when Deco requires a Stop Depth greater than 70 FT (21 M). It will also
enter VGM if Deco is activated during a dive in FREE mode, described later.
Operation would then continue in VGM during the remainder of that dive and for 24 hours after surfacing. VGM turns the
unit into a digital instrument without any decompression or oxygen related calculations or displays.
