VTX OPERATING MANUAL
© 2002 Design, 2014 Doc. No. 12-5382-r01 (10/24/14)
CONDITIONAL VIOLATION (CV)
Upon ascent above the required Deco Stop Depth, operation will enter CV during which no off gassing credit will be given,
meaning Deco Stop Time and TAT will not decrease. A penalty time of 1 1/2 minutes will be added for each minute above the
required Stop Depth.
The Audible will sound for 10 seconds during which the full TLBG will flash. The graphics DOWN TO STOP with down arrow &
stop bar icon, and Stop Depth & Time, all red, will flash (Fig. 50) until descent is made to below the required Stop Depth, then
the Deco Stop Main will be displayed.
• S (< 2 sec) - to silence Audible.
> Other button operations and displays are similar to Deco.
If descent below the required Deco Stop Depth is made within 5 minutes, operation will resume in Deco with off gassing credit
given (Stop Time and TAT will decrease).
--------------------------------------------------------------------------------------------------------------------------------------
DELAYED VIOLATION 1 (DV1)
Once above the Deco Stop Depth for more than 5 minutes, operation will enter DV1 which is a continuation of CV*.
*The difference between DV1 and CV is that DV1 causes operation to enter Violation Gauge Mode (VGM) 5 minutes after surfacing from that dive.
The Audible, which cannot be silenced by pressing S, will sound for 10 seconds. The graphics DOWN TO STOP wih down ar-
row & stop bar icon, and Stop Depth & Time, all red, will flash (Fig. 51) until descent is made to below the required Stop Depth,
then the Deco Stop Main will be displayed.
> Button operations and displays are similar to Deco.
When descent below the required Deco Stop Depth is made, operation will resume in Deco with off gassing credit given (Stop
Time and TAT will decrease).
--------------------------------------------------------------------------------------------------------------------------------------
DELAYED VIOLATION 2 (DV2)
If the calculated Deco obligation requires a Stop Depth between 60 FT (18 M) and 70 FT (21 M), operation will enter DV2.
Upon entry into DV2*, the Audible will sound during which the full TLBG will flash.
*The difference between DV2 and general Deco is that DV2 causes operation to enter VGM 5 minutes after surfacing from that dive.
> Once within 10 FT (3 M) of and below the required Stop Depth, the full Stop icon (Arrows with Stop Bar) will be displayed
solid (Fig. 52).
> Button operations and displays are similar to Deco.
--------------------------------------------------------------------------------------------------------------------------------------
DELAYED VIOLATION 3 (DV3)
Upon descent deeper than the 330 FT (100 M)*, the Audible will sound for 10 seconds.
*Beyond this depth, the VTX cannot accurately perform calculations and display data.
Upon ascending above 330 FT (100 M), Current Depth will be restored, however, Max Depth will display 3 dashes for the
remainder of that dive. Also, the Log for that dive will display 3 dashes as the Max Depth.
DV3 MAIN, information includes (Fig. 53) -
> Current Depth as dashes ( - - - ) with FT (or M) icon.
> Graphics GO UP TOO DEEP with Up Arrows (red), flashing.
> Graphic GAS 1 (or 2, 3, 4), one in use.
> Pressure with PSI (or BAR) icon, if the Receiver and Transmitter are active, flashing when Link is lost; or graphic SPG.
> Gas Time Remaining (min) with icon, blank if SPG.
> TLBG (TL), VARI (AR) while ascending.
> Low Battery icon - yellow (if voltage is at the warning level), or red flashing (if voltage is at the alarm level).
• A (2 sec) - to access Adjust Brightness.
• A (< 2 sec) - to access ALT.
• M (2 sec) - to access the Gas/TMT Switch Menu*.
• S (< 2 sec) - to restore screen Brightness from the Auto Dim level to the % level you last adjusted it to.
• S (< 2 sec) - to acknowledge alarms; this will also restore screen Brightness if it was dimmed by Auto Dim.
• S (2 sec) - to access Compass*.
*These items can only be accessed while viewing the Main.
