500AI
CONDITIONAL VIOLATION MODE
The 500AI will enter the Conditional Violation Mode if you ascend shal-
lower (Fig. 69a) than the Required Decompression Ceiling Stop Depth
displayed (Fig. 69b).
The Audible Alarm will beep once per second* and the Total Ascent Time dis-
play (Fig. 69c) will flash until you descend below the Required Stop Depth.
*If the Audible Alarm feature was set to OFF prior to the dive, only a
double beep will be emitted to alert you.
If you descend below the required decompression ceiling before 5 minutes have
elapsed, the 500AI will continue to function in Decompression Dive Mode. In
this case, no off-gassing credit will be given, and for each minute above the
ceiling 1

/

minutes of penalty time is added to Required Stop Time.
The added penalty decompression time will have to be 'worked off' first, before
obtaining off-gassing credit. Once the penalty time is worked-off, and off-gas-
sing credit begins, required decompression Stop Depths and Time will decrease
toward zero, then the Nitrogen Bar Graph will recede into the yellow Caution
Zone and the 500AI will revert to the No Decompression Dive Mode.
