This mode calculates dive depth and time limits. To do so, it accounts for any residual nitrogen, oxygen, surface intervals, the programmed gas mix,
and PO
alarm setting. Either SAFE MINUTES (No Decompression Time) or SAFE MINUTES O2 (Oxygen Toxicity Time) limits are displayed, depend-
2
ing on whether nitrogen or oxygen levels will be the limiting factor. The time limit will display as 1-599 minutes, all times greater than 599 display as
"599".
NOTE: Depths exceeding the MOD (Maximum Operating Depth), if nitrox, or that have less than 1 minute allowed dive time will not be dis-
