DELAYED VIOLATION # 1 (DV1)
DV1 is a continuation of CV which occurs if you remain above the Stop Depth for longer than 5 min-
utes. At 5 minutes, the Audible Alarm will sound (even if set Off), the Down Arrow icon, Total As-
cent Time, and full N2BG will flash, and the message DOWN >> TO >> STOP will scroll (Fig. 71),
until you descend to the Required Stop Depth indicated.
While above the Required Stop Depth, no off gassing credit will be given and for each minute that you
remain above the Required Stop Depth indicated, 1.5 minutes of Penalty Time will be added to the
Deco Stop Time and Total Ascent Time.
DELAYED VIOLATION # 2 (DV2)
When the Required Deco Stop Depth is greater than 60 FT (18 M), but less than 70 FT (21 M), opera-
tion enters DV2. The Audible Alarm will sound (even if set Off), the Up Arrow icon and full N2BG
flash and the message DECO >> STOP >> 60FT (or 18M) will scroll (Fig. 72).
To get back to the surface, you would have to ascend to just deeper than 60 FT (18 M), staying as
close to that Depth as possible until the Stop Depth of 50 FT (15 M) appears. You would then con-
tinue to follow the Decompression Schedule indicated to the surface.
DELAYED VIOLATION # 3 (DV3)
When the Max Operating Depth (MOD) of 330 FT (99.9 M) is exceeded, or 399 FT (120 M) when
Digital Gauge Mode is set ON, operation enters DV3 displaying Current Depth and Max Depth as 3
dashes (- - -) signifying out of range.
