BUD OPERATING MANUAL
© 2002 Design, 2011 Doc. No. 12-5259-r01 (7/21/11)
DV 3 (DELAYED VIOLATION 3)
If you descend deeper than the MOD*, DTR and Current Depth will be displayed as with the Depth ones flashing (Fig. 35).
Max Depth on the ALT will also be displayed as 3 dashes.
*MOD is the Max Operating Depth at which the BUD 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.
DTR will be restored if it is accurate, or remain as dashes if not.
VGM (VIOLATION GAUGE MODE)
During NORM dives, operation will enter VGM when Deco requires a Stop Depth greater than 70 FT (21 M).
Operation would then continue in VGM during the remainder of that dive and for 24 hours after surfacing. VGM turns the BUD
into a digital instrument without any decompression or oxygen related calculations or displays.
Upon activation of VGM, the full TLBG with the graphics VIO and UP flash for 10 seconds as a warning (Fig. 36).
VGM Dive Main, after 10 sec information includes (Fig. 37) -
> Graphic VIO (in place of DTR) solid.
> Current Depth with FT (or M) icon.
> Graphic UP, flashing until on surface
> VARI while ascending
• B (< 2 sec) to access ALT (EDT & Max Depth).
VGM on Surface
Upon surfacing, the graphic VIO will alternate with Surface Interval time until the unit shuts off after 24 hours.
The SURF icon will flash during the first 10 minutes (Fig. 38).
Operation will also enter VGM 5 minutes after surfacing from a dive in which a Delayed Violation occurred.
> A full 24 hour continuous surface interval must then be served before all functions are restored.
HIGH PO2
Warning >> at 1.20 (ATA).
Alarm >> at 1.40 (ATA), except in Deco then at 1.60 only.
During No Deco -
When PO2 (partial pressure of oxygen) increases to the Warning level; the PO2 value will alternate with Current Depth for 10
seconds with the graphic UP displayed (Fig. 39).
After 10 seconds, Current Depth is restored. The graphic UP remains on solid until PO2 decreases below 1.20.
If PO2 continues to increase and reaches the Alarm level (1.40), the PO2 value will again alternate with Current Depth and the
graphic UP will flash (Fig. 40) until PO2 is < 1.40.
During Deco -
If PO2 reaches 1.60 while in Deco, the PO2 value (=> 1.60) with icon will alternate with Current Depth (Fig. 41).
When PO2 decreases below 1.60, Current Depth will restored.
No indication is given to ascend (graphic UP), you control action to be taken according to your expertise and training.
