“CNS” clock. This graph increases when you descend due to higher

partial pressures and may decrease when you ascend.

(4) Remaining no-decompression limit (NDL): This is the time that is

remaining (in minutes) before you reach the no-decompression limit.

This NDL time limit increases when you ascend and decreases when

you descend.

(5) Dive time: This is the time spent (in minutes) underwater, measured

from the time you descended below 4 feet (1.2 meters).

(6) Residual nitrogen (N2) bar graph: This is how much nitrogen the

computer assumes your body has absorbed. There are a maximum of

nine bars. When all bars are displayed, it means that you are at or have

exceeded the no-decompression limits.

(7) Depth: This is the current depth.

Secondary underwater screens

While underwater you can change to the secondary diving mode

screens that display additional information. When you switch screens,

temperature, maximum depth, and mixes are displayed.

(1) Maximum depth: This is the maximum depth that has been

reached during the dive. Note: a maximum depth is not shown in this

example, indicating the diver is descending.

(2) Temperature: This is the lowest temperature that has been reached

during the dive.

(3) Mix: The percentage that you set is displayed.

(4) Safety Factor: The safety factor margin that you selected.

To display the secondary diving mode screens:
