If FO2 was set for a numerical value (nitrox), the Oxygen Accumulation (O2) Bar Graph will add segments (green toward red) to represent oxygen accumulation for that dive, or 24 hour period, whichever amount is greater.
VARIABLE ASCENT RATE INDICATOR (Fig. 46b)The Variable Ascent Rate Indicator (VARI) shows how fast you are ascending. When you exceed the maximum recommended ascent rate for the depth you are at (see below), it will enter the red (Too Fast) zone and you will be alerted by the graphic TOO FAST, all segments of the bar graph flashing, an Audible alarm and the red LED Warning Indica- tor, unless set OFF (Fig. 47). The warnings will stop when your ascent rate is slowed.
•At depths greater than 60 feet (18 meters), maximum recommended rate is 60 feet/minute (18 meters/minute).
•At depths of 60 feet (18 meters) and shallower, maxi- mum recommended rate is 30 feet/minute (9 meters/ minute).
