OXYGEN ACCUMULATION BAR GRAPH (O2BG)
(Fig. 43a)
If FO2 was set for a numerical value (nitrox), the Oxygen
Accumulation Bar Graph (O2BG) 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. 44a)
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 Indicator (unless set OFF). The warn-
ings will stop when your ascent rate is slowed.
At depths greater than 60 feet (18 meters), maximum recom-
mended rate is 60 feet/minute (18 meters/minute).
At depths of 60 feet (18 meters) and shallower, maximum
recommended rate is 30 feet/minute (9 meters/minute).
Refer to page 11 for additional information pertaining
to the Variable Ascent Rate Indicator.
