Delayed Violation 1, 2, 3 - Sherwood Scuba Profile Manual

DELAYED VIOLATION # 1 (DV1)
DV1 is a continuation of CV which occurs if you remain above the Stop Depth for longer than 5
minutes. After 5 minutes, the Down Arrow icon will continue to flash and the message DOWN >>
TO >> STOP will continue to scroll. In addition, Total Ascent Time and the full N2BG will flash
(Fig. 40) 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), op-
eration enters DV2. The full N2BG flash and the message DECO >> STOP >> 60FT (or 18M) will
scroll (Fig. 41).
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, operation enters DV3 dis-
playing Current Depth and Max Depth as 3 dashes (- - -) signifying out of range.
