The Nitrogen Bar Graph monitors 12 different nitrogen compartments simultaneously and dis-
plays the one that is in control of your dive at that time. It is divided into a green No Decom-
pression zone, a yellow Caution zone, and a red DECO (decompression) zone.
The yellow Caution zone gives a visual representation of just how close you are to the no decom-
pression limit which allows you to make a decision regarding safety stop duration.
The red DECO zone alerts you to focus your attention on the current required DECO stop 'ceil-
ing' depth indicated by the bar graph segment. When stop depths of 50 FT (15 M) and 60 FT (18
M) are required, all red segments are displayed and the required stop depth is displayed numeri-
cally.
DEPTH DISPLAYS
The Depth display indicates depths from 0 to 330 feet (99.9 meters) in 1 foot (.1 meter) incre-
ments.
During a dive, Current Depth is displayed continuously on the Main display with the symbol FT
(or M) below it (Fig. 4a).
When the button is pressed to view the first Alternate display, Maximum Depth and the symbols
MAX and FT (or M) below it (Fig. 5a) are displayed in place of Current Depth.
